I think I am regretting my spring selection

Should also mention that clintfocus is absolutely right on how front tire size and compound plays into things, but even if it were a 255 RS3 or the like, I

all hz's aside, just from my ricer math, a car with something like 275-285 up front, like what i run, even on a entry level r compound, 14kg is what id put up there no hesitation, and that's still on the compliant side for the bumpy socal tracks. but if the dampers dont do there just the car will get unsettled, which more so may be Cossie's issue with those Fortune's (no offense).

the day i DO run something like that up front, ill be on a custom valved KW, or a JRZ double adjustable damper.

I used custom double motons last couple of years, but I am switching to Penske for 2014. I've gone as high as 1200lb on the front of my car, but while it transitions great (315 Hoosier A6's), the point of diminishing return overall is right around 1000lb on front. Anything over 1000lb, again while better on transition, sacrifices in sweeper grip. That said, part of that was not having quite enough camber as well. Unless something has changed, the major issue with KW is that they won't custom valve anything until you get to the motorsports line, which has very little following in the U.S. They certainly are not a poor product, though.
