Hey there guys. Trying to figure out a weird handling issue my dad's 1st Gen CTS-V has.
He purchased and installed the D2 coilover kit, but is using them as purchased from a vendor without changing the springs out at all.
(I've been reading about potential issues with this).
Essentially, on right hand turns, the rear end jumps all over the place.....but the more you lean it over and let the sway bars work, it seems to go away.
We have H&R springs ready to install....is the remedy to swap the D2 coilover's springs out at all 4 corners? Just the rear?
I super appreciate the help in this. The car does have a Creative Steel Ford 8.8 IRS with big axles, and a bunch of other stuff (LQ9 427 with forged internals, ported LS3 heads, etc).
