View Full Version : D2 Coilovers

About to pull the trigger on the D2 coilovers and just wondering if anyone has any reason why I shouldn't? From what I have read they are the same as the Ksports and that if I wasn't going to be hitting the track much then they would be perfect.

Also, anyone ever ordered from APTuned.com? They seemed to have the best price at $950 with free shipping.

From what I know they will work fine for everyday use... I have the opinion that KSport is junk, but I am reasonable... Doesn't make sense to spend $2000+ if you don't track the car. I believe there is a member here that has D2 and tracks his car... Can't recall his name though

Thanks Skidmarcx. Do you know if there are any other options in this price range? Hard to justify 2k+ when it might see a track once or twice a year but I also don't want something that I won't be satisfied with.

K-sport and D2 are your only two options in that range. Or the ground control kit that uses factory shocks for $500.

Mostly depends on how low you wanna go... Running the D2 set will be easier than GC kit and leveling spacers

You can get them a little cheaper than that if you make an offer on eBay.

I tried making an offer on 2 from different sellers a couple days ago. Offered 800 on both. One was declined and the other sent a counter offer of $956

I put around 20,000 miles on my 05 V with D2 coilovers and they were great. Only thing I found was the spring rates were weak for track duty. I just replaced with an aftermarket coilover spring, Got um off fleabay for around $950 iirc.

Nowhere near the quality of KW but at less than half the price, get what you pay for.

My interest would be drag racing and aggressive street driving. I'm not tracking the car other than in a straight line at the strip the odd time so how are they for launching? Just curious if anyone has experience with a k-sport or D2 kit on a car they take to the 1/4 mile?

Your idea of aggressive and mine is much different.

I can fit two fingers between my wheels and the (rolled) sheet metal at an angle. Thus far, I've torn through three sets of front wheel well covers and paid $1000 to repaint and repair my fenders despite having 650 in-lb springs in the front. If I saw you drive, I'd probably say you baby it. Also, your back end is 1-2" lower than your front end.

I love that slammed look but not at the expense of ripping up my brand new front bumper cover, fender liners or smashing my headers on speed bumps. I gotta keep it somewhat practical since I drive mine daily and there are many steep driveways and stuff around here. H&R height is practical IMO... Maybe a tad lower but I wouldn't even make it in my driveway if it was sittin like urs tonytone. However, tuckin tire like that def looks sick bro!

I love the way your V looks tony tone but with the roads around here and how aggressive I drive, I don't think I will be tucking rubber anytime soon. I just want to close up the gap and hopefully eliminate some body role at the same time.

$950 shipped was the cheapest I could find and that was after calling a few places and trying to talk them down. Bought them from NeverEnoughAuto.com.

Edit: @ etcts-v - I plan to take a bunch of pics. Hoping I can help people that are in the same boat as me. There are hardly any threads on these coilovers.

Well.... I am stuck until Monday and kinda irritated.

If you buy this setup MAKE SURE TO PURCHASE THE NUT THAT FITS THE BOLT FOR THE BOTTOM OF THE REAR STRUT before you start the install. The original is welded to the stock strut and now I am stuck until tomorrow because the only places that have it are Napa or Fastenal and they are both closed on sunday....

Also, sorry guys but I didn't get a bunch of pics. Kept forgetting. I did get a few and I'll post them up in a little while.

My factory endlinks are still going strong but I was actually just looking at others to change them out.

The ride is a little stiffer but I wouldn't say jarring. I was actually expecting it to be a lot stiffer than it was.

The ride feels about the same really. Everything just feels more planted. Going through a curve at the speeds i usually do feels like I am going slow now. I am planning to lower the back a little more but the front is as low as I can take it without scrubbing when I hit a big dip or bump in the road.

Some more D2 smack for ya, I did some espairmentin with these awhile back and as you can see it is possible to convert these to true coilover rear with the parts they come with. Since the rear shock body is threaded you can use the rear spring adjuster, thread it onto shock and I had to use the front 8 inch coil spring. The rears are 10 inch and will work on the front. Not ideal as I had run front adjuster all the way down to get a 10 inch spring to work on the front.
Second picture shows a 10 inch 625# hyperco 2.5 front spring. Should have used an 8 or 9 inch. I felt that I needed a bump stop in the front so I cut down the stock ont from my FE4s. Thats what you see in the pics.
Hope this aint too many pictures to post here. I just had them so wth. More on my photobucket if you wana see more on this shit.

Never drove it that way. I just put them together real quick when I first got them to see if it was possible.
As far as changing the front spring to a stiffer hyperco, I had to do that for track duty. Rear also. Springs that come with are too wimpy for track use.
10 inch rear and I would go with a 9 inch front 2.5 I.D

Has anyone ever truly figured out if the rear shock towers are actually safe being load bearing for a coilover setup? Has anyone ever had any failures in that area? After all, that spot is just sheet metal meant to support the load from a shock, not the weight of the car.

Yes they are. LG motorsport setup utilizes the rear shock tower for its 4 corner cooilover and it is just fine. And LG knows what they are doing.

I have the D2 kit sitting in my garage that will be run in a 4 corner soilover setup but have more pressing issues to tend to as my first track day cause my radiator to puke its guts.

Reason for running stiffer in the back?
Most all my vehicles Run stiffer in front than rear.

garrettg
11-01-2012, 06:32 PM
The rate of motion is different between front and back(affecting the amount of spring rate seen by the wheel) so even though the rear is using a stiffer spring the wheel rate will be higher in the front of the car due to the extra leverage created by the spring position in the front suspension. I don't have the exact numbers but most spring kit's available for the V1 come with a higher rear spring rate or equal at all corners. However the kw v3 kit does not follow this rule and comes with a stiffer front spring but some including myself have opted for stiffer rear springs when using the kw kit to balance things back out.

If you moved the rear spring from the control arm to the coil-over location the rate of motion in the rear suspension would increase and running a stiffer spring in the back may not be the ticket.

Breaking
11-01-2012, 06:55 PM
makes sense. Thanks.

Onefast V
11-01-2012, 06:58 PM
what garrettg said. to get the wheel rates to be similar the rear needs to run stiffer due to the spring being significantly more inboard in the rear than in the front.

If you move the spring to the shock/strut mount, you need to significantly reduce the spring rate by as almost 50% to maintain the same wheel rate.

I was considering the K=sports for a long time until I spoke with someone on this forum about them. i don't want to say who they are on here, but I'm sure they will chime in. Anyway the k-sports were more problematic then they were worth and he ended up ditching them for some lowering springs and QA1s. The K-sports will also not work with aftermarket rear sway bars.

I got this off of cadilacforums.com here is the url

Yes KW's do work with the Hotchkis kit.

I'm trying to figure out if id be better buying QA1's with my H&R springs and get the hotchkis sway kit if the D2s and ksports are unable to run aftermarket sways.

Hotchkis sways are a huge improvement, you need adjustable endlinks with them. I spent the money and got powergrid ones which I am very happy with. I still need to roll my fenders with stock 245/45/r18's, because of my ride height. Also going to switch to a slightly lower profile tire and run 255/35 front and 265/35 in the rear.

I find it very hard to believe that the ksport/d2 coil overs would have any impact on the installation of sway bars. But remember as soon as you lower the car you will need adjustable endlinks as Dmax stated.

why do you need adjustable endlinks for springs? and do you guys think d2s have the capablity of running hotchkis sways? plz someone with d2s answer this question because if they can't then im going h&rs with QA1s and hotchkis sways I'd spend more that way but I reall want the run aftrmarket sways to eliminate as much roll as possible.

I went straight from stock to d2 which is springs and shocks. I think the handling improvement is very noticeable. the ride is definitely for firm. I won't really know until i take it to the road course in the next couple weeks. I will say the stiffer springs and shocks make the car feel more "snappy" at the limit.

Did anyone ever end up actually running these as true coil overs? Also, what spring rates would you recommend for running D2's? Front and rear (rear as true coil overs).

Side note, why would anyone go with factory shocks when you can pick up a set of these for the same price?:confused: I think the price for factory suspension on these cars is ridiculous. 160-250$ a shock? come on.

They only come in one spring rate no options, i have already asked. 550/550. assume another $200 minimum for springs. squatting under hard acceleration is a good thing if you want traction in a straight line... The squat less but still squat. they also dive less but still dive. if you run stiffer springs you will reduce the squatting and diving.

From what i understand they come with 550/550 springs which yes, the consensus is they are too soft.

Fuzzy where did you get those spring rubbers?

Then you're buying the wrong Eibach springs. The "250" designation means 2.50" spring. You'll be needing xxxx.225.xxxx springs. I don't know what length. If you try to run 800 in-lb linear springs directly, you'll be getting very little in terms of comfort. The only way that I get away with it is a dual-rate spring setup.

The spring rubbers are Steele 70-2664-35 ($19.90 apiece) for 2.50" springs. You can buy them directly from here (http://www.springrubber.com/?section=4). They don't offer 2.25" rubbers, though.

I would highly recommend against running 550# in the rear as a true coil over setup. when you move the spring out board that far you are greatly affecting the effective wheel rate. this is why LG motorsports coilovers run 400# in the rear springs. 400# in true coilover setup is roughly the same as a 750# rear spring when traditionally mounted. the 550# would be MUCH stiffer.

Ya, It is difficult to compare accurately the "base" models of each one. They all seem to have the same basic abilities though, compression and rebound adjustability (how much is unknown), ride height, pre load etc...

Is there anything comparable to the kw setup? It seems like the only options are the d2/ksport then the kw v3 and then custom from penske, lg etc. I wish there was something like the pss9 or pss10s from bilstein. Have had good luck with those.

My dual-rate setup with a set of QA1's might give a set of KW3s a run for its money. As best I can tell, TC1578B and TC3025P are the correct part numbers for the front and rear shocks, respectively. $240 for each front shock and $210 for each rear shock. Apparently, QA1s are perfectly compatible with the Ground Control kit.

Therefore, you're looking at:

$500 for the Ground Control kit with your selection of primary springs
$400 for your selection of Eibach tender springs
$150 for Steele spring rubbers and Eibach isolators
$75 for adjustable end links
$900 for QA1 shocks
Bottom Line: $2025

Minus whatever you can get for your old stuff (if anything). The real market for this solution are guys that already have the Ground Control kit, because then the investment is a lot less. If we had 10+ people with Ground Control kits that wanted to be free of the FG2 tyranny, I'd put together a group buy. But I wouldn't expect the shocks to come down more than $200 per set (~$700 EST).

So what is the overall ride quality, and performance of the D2 compared to the stock suspension, and compared to using HR or Eibach springs??

Compared to OEM it is firmer but not overly harsh. I drove it 200 miles across northern california and was perfectly comfortable. again the dampers are 32 way adjustable so you can in fact change how harsh or plush the car rides (I'm 9 click softer from the harshest setting. it is consider the lowest race damper setting according to D2). If you are not planning an aggressive drop and don't intend to track the car, the springs included in the kit are more than sufficient. however with a decent drop and at my hp levels i had major tire rub issues at WOT and had to raise the rear end.

If there's enough interest, I will aggressively coordinate another group buy (and probably go 4 for 4 for the events I've organized thus far).

sounds good !

If you buy this setup MAKE SURE TO PURCHASE THE NUT THAT FITS THE BOLT FOR THE BOTTOM OF THE REAR STRUT before you start the install. The original is welded to the stock strut and now I am stuck until tomorrow because the only places that have it are Napa or Fastenal and they are both closed on sunday.

Bump from the dead.

Does anyone know what bolt he is talking about? What is the part number and where can you order this from?

Sounds like he's referring to the BOLT FOR THE BOTTOM OF THE REAR STRUT. There's only one bolt at the bottom of the rear strut, so it's probably that one. If you look at the stock rear dampers, the nut is welded on there. You can unthread the bolt, but if the D2s don't have the nut welded on (and apparently they don't), then you'll need to buy one.

I took an impact to my factory welded nut and buzzed it off...re-used it. Done and done

Finally got mine setup; true coilover in the rear.

I put the rear springs(9") on the front; needed to be a little softer and offered more adjustment and temporarily put some 7" ebay type springs on the rear. They were supposed to be 350s, but I doubt it.

It does drive ALOT better than worn out stockers, but not as good as I think it should.

I am going to eventually get Swifts but thought I would throw my .02 out there.

So what's your settings at so far (height & stiffness)? And how's the ride comfort with your current setup? I'm thinking about going with the d2's since my car is strictly a daily driver and would rather not spend $2k on suspension.

how short of a spring would you need to go in the rear in order to make it usable for lowering the car some more? 6", 5"?

and can you comment on inboard clearance with the wheel and tire?

So, got my shocks adjusted 15 from soft and it feels good.

The spring frequencies are slightly off and so I started thinking....

These are entry level 1/2 Coilovers made for "racing".

I will probably NEVER Road Race this car.

These springs are too harsh for me, so I am going to look at replacing them with softer and with matching frequencies.

If it is too soft in the rear; squat is not a bad thing in straight-line racing.

Off to the "Google" to do some research and see what I can find based on FuzzyLogics work......

I've shared this many times but it is pretty much the best written/fully comprehensive guide on coil overs. It should give you some insight as to what is the proper frequency for what you are looking for and what the proper ratio is front to rear.

Ok, I've put in an offer on the ebay dealer. What's the final best rear spring option for true coilover? I've read 400. Is that still it?

I'm not a track guy, so a fun on curves, but comfortable ride is my goal. I've got speed bumps in my neighborhood coming/going. I've found that if I hit them at 10mph, it's not super jarring, definitely better than crawling over them.

Has anyone used Creative Steel's full front & rear control arm bushings set with the D2s? I'm curious about this statement:
NOTE: The stock OEM bushings have torsional resistance because the metal insert is molded to the rubber; our bushings allow the metal insert to spin freely. If you are running aftermarket springs/shocks, you may need to adjust them for this factor.

ideally 700F/400R. However dropping those down equal percentages (not absolute vlaues) should be okay for a "softer" ride (I.E. 630F/360R).

I bought MN_V's MM spacers thinking I would install them. I got to talking to my mechanic about it & the stuff I was going to have done, if I did the coilovers now, it'd be easier than waiting & doing it later. My bank account is oh so much lighter now too.

Here's the list of parts going on the car in a week or two:
kooks headers
D2 coilovers
CS rear LCAs
AWH axles
CS motor mounts
CS trans mount
CS diff mount
new tires + tpms
new calipers all the way around
philstine's new clutch master cylinder
hurst shifter with new bezel

I might do all new control arm bushing's if CS can answer the question I posted above regard the CABs + after market springs/struts. Was also considering cradle bushings too.

Also, they'll fix the leak in my diff while in there & hopefully get my seat warmers working again.

if you want a low maintenance solution stick to rubber. on most of the control arm bushings you will never notice the difference between rubber and poly unless you are pushing the car very hard (I.E. race track)

I highly doubt your control arm bushings are FUBAR unless you relentlessly abuse your car. The easiest way to check is to jack up the car (on the lower control arm to keep the suspension loaded) remove the wheel on the corner in question, unbolt and separate the ball joint from the knuckle and check to see if there is any lateral (side to side) play in the control arm. If you don't mind greasing them ever few months or when they get noisy you can always get the softer durometer poly and it will not impact the ride in a noticeable fashion. If you do that I would get the CS bushings for ease of greasing.

Well, I had this highly annoying croaking/creaking sound on my right front wheel on up/down travel. You can be parked, push down on the fender & hear it. The strut mount up top looked solid & not loose. I'll just wait to hear what the verdict is from the mechanic when I drop it off MON to get all stuff I've purchased installed.
