I just got back from practice at trcr after the races were over and the grip was awesome. I have been running same shock setup as WC, but today went back to 30wt oil in the rear and I felt like I had a bit more grip. Then after a while I tried my kyosho springs... Pink/gold . I beat my fastest lap of the session 2 times. By just a few tenths but.. the Kcar springs were feeling really dialed tonight. Anyone else using them??
