STOP YELLING! (PLEASE)
for a person that seems hell bent on taking over the TSM race series, I find your question a bit amazing.........
in any case, start with a 10 lb differential right to left (ie 20 and 10)...for a rough idea, take a look at the stripes you put down under load (concrete works best) and try and get them even in density...then you have to go to the track and experiment with what works best for your launch/tires/track
FWIW, I use 15 and 5, but I do have the ATR bar
