We raced at Quincy Il. Kart hooked up good with white maxxis with 4 once’s of pink panther in right side tires and 2 once’s in left tires, rolled them 24 hours . All good, then it dropped in 40’s at night and maybe 60 in daytime and we went to indoor races at palmyra Mo and the back tire had no bite, so thought it was the sandy dirt indoor, then went to fulton Mo and same thing yesterday, rear tires have no grip. The stuff we whip on them is I believe black 2.0 got it from Carlson, everything was great till cold weather.. lol the kart is a phantom minecon 2022 , 61 percent left 70 cross and 45.5 front.
