Comments:
1. Best improvement: Front end rebuild! Stock suspension had 135,000 miles on it when I bought the car. Currently I have rubber LCA bushings, Moog rubber UCA bushings and urethane strut rod bushings.
2. Least effective improvement: Hard to determine.
3. Next improvement: Tires!
4. Above car handles IMO on a 1-10 ( 10 best Z06, 1 yugo): 7
For years I dealt with an oversteer condition. I liked how flat and level the car stayed in the turns but the twitchy feel made it hard to feel confident if I wanted to press it hard into a turn. I was running a 7/8" axle hung Addco rear sway bar. I tried rubber end link bushings, tire pressure changes and it still wasn't right. I recently switched to a smaller rear bar; a 3/4" frame hung version that came stock on an 83 Imperial. The car felt better but still wasn't neutral. Last week I installed bigger torsion bars, out went the 1.0 and in went the 1.15s. I also changed the shocks at the same time from KYBs to Bilsteins. The ride improved, the oversteer went away and the car is much more fun to drive. The car has enough power to kick the tail out if I feel I need to. I no longer have to coast or brake through the turns to avoid drifting!
