Can someone tell me what diff fluid and shock fluids to use on clay tracks? The car is on it's way but I am going to the hobby ship now so wanted to pick some up. Only a couple small/medium jumps, medium bite. Thank you !! Whatever weights that will help with traction. I always seem to have traction problems no matter what track I run on. I am still fairly new to racing so a lot of it is most likely driver error and throttle usage
