I started off thinking a lower center of gravity would help more than keeping the geometry right (keeping the A arms in a position to make best use of the strut and steering arm). I ran it like that and had been lap times then stock. After a few classes and seat time, I found out for myself lower isn't always better. I raised it up (was running Ground Pounder coilovers with Bilsteins) and I cut seconds off my lap times with no other changes. Just something to think about. I also got rid of my long tubes. They added power up high in the RPM range, but the place my car suffered was down low on the track. I could corner with the best of them, but it sucked getting speed after coming out of the corner. I redid the exhaust using stock manifolds, catted H pipe and Spin Tech side exit mufflers. It made peak tq alot lower in the RPM range. Peak HP is good for dyno sheets and forum signatures, but usable power is all that matters on the road courses. I get what you mean now about the springs. Makes sense. What rate are you thinking of? In the end I went with this:Up front - tubular K member, fox body tubular A arms, '01 Roush Stage 3 springs (cut one coil), fox body Bilstein HD, Roush sway bar, 13" front rotors (Baer), Roush calipers, SS lines, Hawk HP pads, Flaming River rack and pinion, Steeda x2 ball joints.Out back - Roush tubular lower control arms, stock uppers, '01 RS3 springs, fox body Bilstein HD, 13" rotors (Baer), Hawk HP pads, stock GT sway bar.I ran strut tower and shock tower braces from Kenny Brown for awhile, but got rid of both when I supercharged the car. Didn't see a loss afterwards. Are you thinking of a different wheel/tire combo for track use? I ran 18x9/18x10 combo for awhile, but switched to a set of 17x8 running 275/40 R compound all around and could carry more speed into the corners.</blockquote>
