Need some help/tips everyone... Took my sc10 to the track today and I was having problems with keeping my rear end from sliding all over the place. I run on a hard packed tight clay track with a 13.5 motor and gold barcodes in the front and rear...... Should I try loosening up the ball diff, loosen the spur, add rear swaybar? Basically any help would be greatly appreciated so that my rear is more planted and not sliding all over the track like it has been and spinning out alot.........
