4wd tires have been Pink Taper Front/BK Bar Rear, Goosebumps all around or DD's all around, Holeshots around works well too. The shop stocks B44 and Kyosho 4wd parts. There are a couple of us sponsored by Schumacher so if you are running a Cat SX find me, Raul, or Ron for setups or parts needs. The track is an absolute blast, well run, friendly racers. The owners John, Hilde, and Mark are great people and can give you a ton of setup advice. You'll have a blast if you come and will be a part of some great 4wd competition.
