It depends how far you would want to go with it, but yes an adjustable or performance shock would be a good start or performance sway bars especially if your car did not come with a rear one. I don't know how crazy you would be about the idea, but a lowering spring can help A LOT as well. Just switching to a 1" lowering spring from Hotchkis i noticed a huge gain in handling quality, but if you do switch springs i would highly suggest a performance shock as well.

If you really want to get some technical data and firm responses on what to do check out pro-touring.com

KYB gas-adjust shocks, a slightly bigger front sway bar, and a rear sway bar with the boxed contrrol arms will help a LOT without hurting the ride or value of the car.

thanks for the info, the rear seems tighter than the front, much less bounce and sway,the front recoils twice after pushing down on the fender and it sways back and forth left and right. i'd like to tighten up the front, feels like i'm driving a 350 hp. stagecoach

When were the springs last replaced? That can make a big difference too. You may have original front springs in it since they're alot tougher to change than the rears. Rears may have been replaced. If the housing on the front shocks have spiral indentations there's a good chance they're original. I have first hand knowledge with those. I couldn't believe it that I was the first one too change my front shocks.... Shocks and springs made a big difference in handling. Sway bar and end link bushings could be shot too and need replacing...

Good point, GG. I had assumed his suspension was refurbished, but stock. Yes, very important to refresh the bushings, tie rod ends, ball joints, etc. and coil springs as well. Not fun, not really cheap, but do it once and you're good to go another 100k miles! Those lower control arm bushings are no fun at all!!!

I think that the above aftermarket items, while excellent for high performance usage and improved handling, would both hurt the value and ride quality of the original, numbers-matching car in question. Harp wants to restore his vehicle's ride and handling qualities, I think. Turning it into a modified canyon carver, (always an option!) is not the main focus here. I've driven highly modified A bodies, and they handle like a new Corvette. Unfortunately, they ride very stiffly and are uncomfortable on long trips.

buy/add the modern stuff, keep the old in a box. Swap back if you ever sell to retain value?
