I fixed that this weekend with these pistons and the new black springs. Very happy. I ran the 1.2x8 with ae 45/40 oils f/r. 9.25 front spring, 10.75 rear. Loads of front grip now. To me the car always felt like it had too much rear grip..the trick was to get more front grip with all the rear grip still there..more grip everywhere lol. Car insane now.
