RE: Race Ramp source for Radicals

@davidf We use this same set up in our 20ft Stealth trailer. We did add about 24 inched of 1/4 plywood in the trailer for the front wheels to ride on to prevent the car from bottoming out when pullin...

@jeff-alton, have fun and work your way up to speed slowly. Just to warn you there is a common “heart attack moment” that almost every new SR3 owner has. Once you are out on the track for a while an...

RE: Getting SR3 up to temp?
