The Slapmaster is a lot braver than me, the front of my car runs .55's or if the back feels really stuck I run .50's. The car steers hard no matter what I do, but other people drive my car and say it's lazy...
I just realized that if I'm honest I am probably no longer qualified to give 1/12 scale setup advice. My cars setup is so weird people ask how it's drivable, let alone fast.
