Smoking fast time at SOW with street tires. Fast using any tire for that matter!
Thx that was during official time attack season warmup practice with official timing. There was actually more in it bc I had brake issues (this was with crap pads and before I had figured out the precharge pump connector workaround to completely kill PSM).

I ran my KW V3 with KW V3 off the shelf springs, mainly bc a track like SoW premieres a soft car. When I tested R-comps later I went to harder springs, 700/900 or smth in that range, I have to look at my old notes.

Sorry, I have not posted in a while (6 weeks) but nothing to report until now.

Kept the spring rates at 685F/970R

Trimmed the bumpstops f/r to allow more travel. The rears had only about 1/8" clearance, the initial installer missed this. Damn those KWs sit low. The rears would not need as much trimming if I went with a Tarrett rear mount, which the stop is higher for more travel.

H&R front bar 25mm on full stiff, OEM GT3 rear bar full soft.

Softened up the rear bump a bit.

Went to the track yesterday (Buttonwillow) for some real testing.

Result: NO PSM coming on cutting the power, NO excessive twitchiness in the rear. Just a little sliding in the rear when pushed a little more. Handled the curbing and bumps much better, no bottoming out.

Buying a front GT3 bar (since I am maxed out on the current one) to see which setting causes understeer and dial it back to run neutral.
