Decent handling susp setup?

What car are we talking about here??? SS springs are designed for drag racing, period. They're constructed to counter act the twisting effect torque has on a hard launch. Replace the SS springs with leaf springs rated to match the 1.03s up front. The arch of the spring should be close to flat with the car at rest which will result in a lower ride height. The 1.03s will allow you to lower the front adjustment to match. You want the car to sit flat to slight nose low. A Helwig tubular 1.125 front sway bar will keep roll under control and keep weight down. Replacing the front upper control arm bushings with Moog K7103 offset bushings will allow for aggressive alignment settings cheaply and easily. Bilstein shocks thru Firm Feel (an excellent source of parts and advice) are valved to handle the 1.03s and stiffer leaf springs and are well worth the cost. Stay away from KYBs. Make sure your breaks are up to slowing down the increased speeds. Sorry, the BFGs are now a major impediment to really realizing how well these cars can handle. There just isn't any support from the tire industry for the 15 inch dia. The best is probably Micky Thompson's SR series but remember your trading longevity for the grip provided by softer tire compounds.
