Hi,
I'm thinking about upgrading my 98 GT's suspension with the GM Handling Upgrade Kit pk12456148 (ex. http://gmpartsdirect.com/results.cfm...ber=pk12456148 + replace all the rubber parts with polyurethane), and I would appreciate your input. I was wondering if this kit would work OK with different springs/struts and anything else that might be needed to eventually upgrade my rim size to 18". Right now I'm running stock 16" rims on a stock suspension, and while the ride is soft and nice for straight-line cruising, I'm really not liking all the body roll I'm getting going around simple easy turns. I'm not into autocross or extreme driving situations; I would just like a good deal more firmness and stability while keeping it soft enough that going over moderate sized bumps doesn't jar my teeth out. If I'm understanding it correctly, the GMPP handling upgrade should still work, even if I later change out the struts/springs/etc. I'm curious to find out if making the jump to an 18" rim size would change the suspension geometry enough to cancel out the handling improvements I might see with this kit. Any thoughts?
(p.s. My car is nearing the 86,000 mile mark, and I know I'll have to replace the struts pretty soon. Just hoping look ahead and to do as much as possible in one shot. Tear it apart once; put it all back together once... and be done.)
