I picked up a set of D2 coilovers a few weeks ago and finally got them installed over the weekend after snow delay. Today I had the car corner balanced and aligned.
I decided to go with the D2s for a few reasons.
First of all I was looking for something that would give me camber adjustment.
Second, I wanted something that used a standard coilover spring, so if I wanted to change rates I can. KW doesn't offer either of these. The rears of the D2 don't use a standard spring, but it doesn't look hard to modify the upper mount on the car to accept one.
Third, the cost is hard to beat.
Finally, I wanted to test them with racing stress. Most of the people that are using them on VS right now are more about stance and slamming the car; neither of which I am interested in. Most have seen the one dramatic failure on here, but it seems like an isolated issue given how many people are using them now and for how long.
Anyway, I will put some high cornering stress on them to see how well they hold up. I might be praising them or cursing them and looking for something new in 3-4 months.
Initial impression is they are stiff, even at the softest setting. Ride wise it isn't as bad as I expected though. You feel a lot more of the little stuff, but the sharp bumps at freeway speed are actually less noticable than with the Weitec setup I had before. I may change the springs at some point to soften it up given the car is also my daily, but I will live with it now.
Brian (68123GT), now with TC Motorsports, just finished up the corner balance and alignment on the car. He said the D2s are much stiffer than the KWs he has on his yellow, or they were when he first drove my car. He eliminated all the preload on the springs and said it felt better. KWs use a progressive spring, or two springs at different rates on the front coilovers, so it probably does ride better.
As soon as I have the weight numbers I will post them up. Was looking to get -2 degrees on the camber, but Brian said one side maxed out at -1.1, so he set both to that. Looks like my subframe bushings are to blame for the frame shifting a little, so I guess its time to go Delrin.
Haven't really had the chance to test it out, but I did take a few corners and I can tell there is an improvement on speed. In fact, I could have gone faster. I would have been maxed with the old setup, but this seemed to handle it easily. Also, the car seems to react faster in a straight line when applying power; I am assuming due to less suspension give.
Ride height is slightly lower than what I had before. No pictures of that yet. Car is filthy and I am going to wash before photos. I do have pics of the front coilovers in the car and will take some pictures of the rear also. I am using them as documentation that the suspension was installed correctly in case of any warranty issues. I am also using the D2 endlinks instead of the QBM ones for the same reason.
