Ft tires should be rolling straight ahead unless car is so tight and not steering in the rear that the side thrust is ripping them off! Ackerman and toe out is important as well as keeping the left ft. loaded to help with steer! This is where a total setup change comes in-- in letting it happen or just trying to make things happen!!! You are not holding your left side down but making it roll, throwing weight instead of just moving the right side down to get steer and letting transfer happen naturally!!! Run a few searches to fit the correct springs to the weight of the car and learn to transfer with nosing and caster settings and not by roll over!!!

You need to run tubes. when I ran bobbys in never rolled a tire off with a tube. RF air pressures as low as 23PSI
