However....what motor turn ppl are using on JV? I would recommend to use 17.5 and slower motor and use the timing board and gearing to archieve the desired speed. Set the brake to ABS and very low power push brake so it won't lock up the rear tires while applying brake and the car will do donuts...since it was running at JV, I think everyone should apply traction compound on the rear foams, and the inner front tires. Steering dual point should be low as you do not want to over turn the car and cause the car doing donut.
Set the side line in TOE-IN position...CRC blue side spring is good and 200k grease on the rear damper....35* oil in shock and stock spring are fine.
