I've been upgrading my suspension to "pro-touring" status, and I thought some of you might be interested in how it turned out.
I'm really excited, since my goal was to have decent handling without ruining the ride. I think I accomplished those goals. Haven't had the opportunity to push the limits yet, but it corners very flat. Still have some drivetrain bugs to work out. The ride is the best part - no harsher than it was even with the ballon-like tires gone. And I live in the land of potholes and railroad tracks!
Before: Orginally I had steel 14x6 with 205/75, and factory worn out everything else.
After: Wheels/Tires Front: 245/45R17 on 17x8 with 5" offset Wheels/Tires Rear: 275/40R17 on 17x9.5 with 5.5" offset. Upper Control Arms (UCA): Detroit Speed with delrin bushings Lower Control Arms (LCA): Speed-Tech Performance with delrin bushings Body Mounts: Competition Engineering Solid Aluminum Anti-roll bar: Hotchkiss 1.25" Hollow Front Springs: NPD C-7412-129 Front Shocks: KYB GR2 Tie Rod Sleeves: Speedtech Rear Springs: Local built 5 leaf with poly urethane Rear Shocks: Edelbrock
Alignment: 1 degree negative camber, 1/16" toe in, 4 degrees postive caster.
The reason I picked the front coils was that I wanted to stay with a factory stiffness spring, and rely on the rest of the suspension to handle the corners. These springs are about 375lbs/in (based on calculation). I compared about 3 springs for my 'vert at NPD and they were all the same coil diameter (vernier calipers) just different number of coils. I have about 3.5" from the fender lip to the top of tire. And best of all, just $55!
I still need to add subframe connectors which is a high priority.
My only other items on the wish list is a variable ratio steering gear to give me better feel and faster response (the factory gear is rather numb especially with my wheel offset).
