(optional) thoughts/opinions:
As I'm building this car for HPDE use, tested out these coilovers for the first time at the track, today. With Karcepts' recommended settings (minus their sway bar), the car felt very soft and a bit bouncy. Their settings are 2 / 6 comp/rebound front, and 3 / 7 rear. It felt a lot more stable after +1 rebound and +4 compression all around. I should probably add a bit more rebound, but did not want to mess with it as I was testing out other things as well (e.g. new pad material).
Does the Karcepts sway bar make a significant difference in your experience?
What spring rates do you guys use for HPDE only track duty? The springs I have with recommended settings felt very soft, and I wonder if I should seek stiffer springs, or just compensate with higher compression and rebound; tough to figure it out without knowing much about this platform : )
