Coilover ride quality? - Page 3 - ZR-1 Net Registry Forums

Just did a quick Google search here is an issue with the QA1's that I haven't heard of:

Also I was speaking to Randy at DRM years ago before I had gone coilovers and we were discussing any failures. He mentioned a C4 that had a high speed off at Sears point (I think if not then maybe the Silver State Classic) this happened in the late 90's, I believe, the vette had the DRM coilover set up on it and I believe he said the vette traveled something like 17 feet before coming back down on its suspension. The mounting points were fine the car on the other had did not look so good.

Here's some old pictues of the 89 despite the abuse over the years it is holding up great. The shocks have been rebuilt (from standard valving to Moracca).

Been considering going to them so I can lower one to one and a half inches (lose the 4x4 look). I have lowered C4's in the past with the long bolt rear and cut rubbers front, while it looked great I did not like the effect on the ride and would not do this to my ZR-1. I see most use 425/275. Does lowering change this rate? if so would I need to go with a lower spring rate?
I do not want to lose the ride I have now would like a rate that will maintain the stock ride or no stiffer than a 96 Z51 (have a 96 LT4/Z51 and its not to bad at all) when ride control is set to performance. car will only be used for lots of road trips. tell me your thoughts on how the ride changed if any and what rates you went with. And yes I'm getting to old to bounce my kidneys all day ..LOL

Thanks Steve

Been there done that.

That is the best spring rate. Best way to lower the car or adjust height in general. Best way to adjust ride height of your car San front and rear springs. Suggest poly to include Banski heim joints with covers for the rear trailing arms/ (dog bones) GC

This is my daily driver and one of my best mods to date
