I won’t know if it makes a difference until tomorrow.Can you list all the P/N's for the ZL1 parts? Do these make a nice difference over the stock parts? I'll be putting on the Koni FSD's next year and I might as well replace these other parts as well while I'm in there.
My rear end is very wallowy. Going from King springs + Koni Sport yellows to Eibach springs + Koni FSD golds made little difference. Aside from being more comfortable and the fact that when I floor it while driving, the rear end will really tighten up now and I can chirp the tires. This is due to the FSD golds tightening up. I haven’t really been able to chirp the tires on a long time. Likely due to the worn out parts/wallowy rear end.
I will be installing everything (subframe bushing inserts as well) tomorrow except for the lower control arms. I installed those a couple of weekends ago. Also, I will be replacing the rear upper control arms with Mevotech arms due to the $17 RockAuto close out deal.
