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.

I have 350s on mine, but they are not a good brand; Too harsh for me.....

There is no real final word, it is really up to you and what you like.

Also it depends if you go full coilover or not. I am full coilover, so make sure you note that.

I am wanting to do full coilover.

Has anyone used Creative Steel's full front & rear control arm bushings set with the D2s? I'm curious about this statement:

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

LAYGO

Ahh, thanks! -10%, got it.

The ebay vendor accepted my offer for $920 for the D2s (after my offer for $933 expired, he said make another offer for $920 & I'll accept it). Maybe he will for you too?

Won't need those MM spacer then

Why would they need MM spacers when you are replacing the struts...? the whole purpose of the MM solution was to fix the nivomat leveling issue that would jack up the rear of the car.

LAYGO

LMAO! I had that exact same thought. I wasn't sure if it'd still be used in conjunction with it or not, but ya, guess I'll have to sell them now if they aren't needed!

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 DD your car, from what I've heard from multiple other owners, forgo the poly bushings. squeek squeek squeek....

Probably great responses on the track though.

And don't get the Banski RSM.

Even with the grease zerts?

Onefast V

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)

Ok. Thanks

Ok, do they sell stock control arm bushings? Or just the entire control arms? Looked quickly on GMPartsDirect . . . couldn't make heads or tails of it.

Are you concerned that your stock bushings are dry rotted or destroyed? I wouldn't see any need to replace them unless they are legitimately damaged. I could only find lower control arm bushings on rock auto.
