Might want to look at your shocks on the stiffness of your rear springs. I tend to like a shock that's valved a bit lighter then what's out there. A long time ago I built a coil over adapter that I could use any shock in I wanted. I used a Koni 90/10 shock in it and it worked pretty good. I bought a new set of coil overs, The old AVOs back when the first came out, and installed them. First thing I noticed was that the were a lot stiffer, I was using 95# springs at the time. That car never ran as consistent after the change.

What shocks are you running? Are they adjustable? Can you send them back to have the valving adjusted? Same questions for the front and back.

I like for the extension of the shocks to be as light as possible and tune from there, both front and back.

Want-a-be. Work slowed down and May was the last time I was out. Have Koni single adjustables on the rear and Koni SPA-1's on the front. Have tightened the front shocks fully like I ran them before. Have been recently setting it up for heads up 10.0 index racing if I get it to behave. Removed the launch control, delay box and rpm activated shifting. Brian

Rear seems very stiff with the 110's. 60' went from average 1.32 to 1.34 on a good track to 1.36 pulling the wheels out of the beams. Last year last pass had 1.052 in box, started with 1.060 in box first pass and was .036 red. Last fall had a best of 1.303 60'.
