Cadillac CTS-V - Who did H&R's and got the perfect height!!!!!

Here is one picture of my car before i lowered it and the rest lowered with mightymouse spacers..........PERFECT stance. Figured there were 8 other H&R threads why not add another. :eyes:

here is stock ride height it wouldnt let me upload into the first post.

that is such a small bore 500hp 13.x flithy slut

Who's the dude photo-bombing pic 3? lol

By the way, I've got a few threads (3 or 4) on the topic of H&R's that you might wanna read. Looks like your drop was a bit different than mine ... ;)

PS -
lowered with mightymouse spacers.........

It wasn't the spacers that lowered ya, it was the springs .. although those spacers KEPT ya lowered in pic 2. :D

Please add me to your list. I modified my rear suspension mounts from what H&R used in their testing and am now complaining with the results. It is too low.

Please advise.

im putting a 22x13 inch wheel on mine at the moment, then ill shoot Cadillac and H&R an email. :D

If the spacers play no part in the lowering of the car......then describe to me why I have the exact same height whether the car sits for 8 days or if i drive it on a 4 hr trip?

i am going to have to ask you to consolidate you 2 posts into one...there is no need for 2 post by the same person in a row in the same thread.

The spacers KEEP you lowered when the car is moving, which is when the Nivomats are active and would otherwise be pumping it back up to OEM ride height. That's why.

So if the H&Rs are lowering me too much, then why doesn't my car drop an inch lower when its parked?

What's "too much" to you? Facts are getting lost in translation here. Let's forget about "too much". I'm saying that MY H&R's (and other member's) gave way more of a drop than they advertised. Period. The only other thing I'm saying is that it's NOT because of the MM spacers either, it's because of the springs. If it were the spacers that were 'making' my car lower, then my taller springs (cut OEM's) would have been pushed down to the same height at the H&R's were. The fact is, the taller springs resulted in a taller ride height. See what I'm saying?
I'm not trying to pick fights here and I'm really trying not to litter this place with back and fourth BS pissing contests. What I AM doing is trying to make sure that the right information is out there for the next guy that comes along wanting to lower his V.

I dont see how you can compare a cut stock spring to an aftermarket spring. Just because the actual sring is taller means absolutely nothing. Its not an apples to apples comparison.

I will measure a stock V and mine on saturday and post results.

Your right...... you cant

By taller springs, I didn't mean physically taller when set beside each other on the garage floor. I just meant springs that achieved a taller ride height.

The whole point is that I kept the MM spacers installed, put different springs in (it doesn't matter whether they were cut or not), and got a taller ride height. This is the pudding that proves that the MM spacers are NOT what determine your ride height. It's the SPRING. MM spacers don't lower you. The spring lowers you. The MM spacer KEEPS you lowered when you're moving and the shocks are trying to auto level.

they both play a factor..... That's what you gotta understand. There should be no fighting match at all. The plain fact that H&R, Eibach..... Whatever Asian spring you put in your car, before and after MM spacers they are going to have a different ride height each time...... end of story. That's why they are sold. For people that dont get the full drop from regular springs.

The spacers themselves don't determine ride height.. They keep the SHOCKS from affecting your ride height. All dependent on relative drop amounts of course. I'm pretty happy with the drop I got from H&Rs and the MM spacers. Like I said before I'll probably shim up the rear by just less than half an inch to get uniform wheel gap front and back, just because I'm super anal. Honestly I could live with the way it is now and be perfectly happy.

I was re-reading a long PDF file that I have that explains how the nimovat shocks work, and some of the details in there really illustrate why the MM spacers allow the rear to sit lower. Biggest factor that affects ride height from the nimovats is that the further you compress them, the more they start to act like a spring themselves, meaning that when you artificially compress the shock further than it's original design intended, (i.e. lowering springs with no spacers) it begins to act like a spring itself, partially supporting the rear weight of the car, and thus keeping the ride height higher than it would be if the same springs were used with non-leveling shocks. It also said that once the rear shocks have reached their "happy place" after driving around, it can be a long time before they re-settle because of the tight internal tolerances of the various valves and chambers. So it's entirely possible that one could be driving around with a rear end that's perpetually "pumped up" by the rear shocks and not ever see or notice the suspension settling to a lower point.

Perfection! :D

I just started looking into to shock spacers so sorry if this is a stupid question but are those RC531 spacers similar or the same as the ones that the member "Nels" is selling?

Looks good to me

I think the RC531s are close.

So your one of the lucky bastards with a lift eh? :(

Top picture on the Before is on stock 245/45 Goodyears and Bottom 2 of befores are one the same size tires as in the after. I have 245/45R18 Front and 275/40R18 Rear. I did have a little "oops" with the spacers, but it was completely my fault. As soon as I fixed my mistake, I have not had a problem since.

H&R with MM on my 06 = Perfect! No rub issues when I drive hard or hit the many pot holes in OK.

The spacers themselves don't determine ride height.. They keep the SHOCKS from affecting your ride height...

What I've been trying to say over and over again. Also what I think I proved by being able to leave the same spacers in and get a different (taller) ride height with a different set of springs.

How's your progress on these shims/spacers for the springs? Sounds like you and I are both equally "A.R.", so whatever you come up with, I'd like to try too! See my other thread(s) for why I'm still looking for alternatives to the cut OEM springs. In short, after another day of driving around I definitely feel a difference from the H&R's, and I'm not a big fan of it. Feels like the ass end is a bit 'waggly' ... like this :shakinass LOL

i have h&r and mm spacers front is a tad lower than i like but still no issues looks just fine, front is lower than rear dont know whats wrong with you car, but you can always put in subframe bushings in the rear to raise ride hieght, and ill take a paypal of 50$ for giving you a solution that actully works

After getting some advice from a few people on here I figured out the problem with my setup. I like the way it sits now, I still need to roll the rear fenders just a bit so I made a bracket to work with the eastwood fender roller, other then that i like the h&r springs.

I ordered 2 pairs of 6x6 rubber sheet stock in 0.375" and 0.500" thicknesses. I already have a sheet of 0.250" rubber laying around that i may try. Should be here either today or early next week. If they get here today I'll probably put the car up on stands for the weekend, pull the rear springs and cut the right pattern out of those sheets. (And also put on my new pads and rotors while its up) I'll try the 0.375 thickness first and see what kind of raise it gets me. From looking at the geometry I expect the 0.375" rubber shim to raise the rear by about .40" or so, but the tape measure will tell for sure. I'll probably post an update and results in my big HR/MM thread over on the caddiforums. Whichever shim set I don't end up using, I'll let ya have for the cost of shipping.

Updates will follow..

No such thing as too much drop IMO! I'm on stock cut springs and homemade billet spacers another member here made at his machine shop. It's low but not low enough for my liking and when driving, the rear lifts up just a tad from the shocks so it's a little rough on the ride. I'll be ordering the H&R's and might mouse spacers soon or just save the coin and go all out with some adjustable coil overs. I cut the springs as a temporary hold me over.

Sounds good Edmund. I'll go over there and make sure I'm still subscribed to that thread.

Mind posting a link to that thread?

I REALLY want to go with H&R's + MM spacers, but all of this talk about lowering too much (and the awful rubbing that ensues) is making me nervous. Add in the fact that my rear fenders will need rolled to accommodate my staggered tire setup and I'm practically a trainwreck. :bang:

Bishop - what size wheels & tires are you running? Send me a PM if you have any questions beyond what's already in the h&r/lowering/rubbing threads and I'd be happy to help you out.

I'm running OEM wheels with:

Front - 245/45R18
Rear - 275/40R18

I even started a thread (http://www.ls1tech.com/forums/cadillac-cts-v-2004-2010/1435324-staggered-tires-hr-springs-mm-spacers-rubbing-issues.html) about it.

I found a place locally that rolls fenders, but they make no guarantees about cracked paint. They also rent the device, which is an option as I have a heat gun. However, the fact still remains, I'm nervous about rolling the rear fenders for fear I'll screw up the paint or it will not provide enough clearance.

I totally understand you're fear of rolling your own ... I'm in the same position, except that I can't get a roller tool anywhere around here either. From what I've been told, even if you can find a roller, they're not going to fit onto your hub without a bracket of some sort to make it fit securly.

I specifically asked the shop that has this tool available if it'll work with a 6-lug setup and they said, "It shouldn't be a problem." Guess I'll just have to head over there and see what they've got.

The tool comes with a hub that's supposed to fit a range of lug patterns. Unfortunately, from what I've learned, 6x115 isn't one of em. They've gotta be Jimmy-rigged up or have an adapter fabricated for that.

Just an FYI for those of u that would liKe a more symmetrical drop from your H&R's (and more room for bigger tires/wheels). Enter the 'Edmod'.

After trailing arms and the soon-to-be-known 'edmod' (3/8 rubber homemade 'washer' under rear spring perches to boost up the 'too low' H&R's), everything is awesome! No more 'reverse rake', no more fender rubbing on tires, no more wheels rubbing on trailing arms, and no more crappy feeling cut OEM springs.

And to be clear, yes, the MM spacers are still installed too.

wes, being those are rubber, doesn't that make it like an extra bump stop making it bounce?

just curious.

i liked it better lower... but wheels look good mane. :)

Thanks Tony.
No, it's not bouncy at all. The ride quality is great. I trimmed about a 3rd off my rear bump stops when I first installed the springs. This 'Edmod' actually keeps you OFF the bump stops since it's effectively a taller spring.
