Front stagger whatever your chassis likes , rear stagger 1.5 " I'd want 2 new sets one 75 cc Internal I like LS 1 , second set 60 cc Internal, one set 3 month old not over 90 cc Internal never wiped aggressive, one more set little older pretty much the same, Liquid Speed prep works great there , LS 1 , LS 2 , LS 3 , every now and then early especially if they get rain the day before the race.
Flip Flop prep works well there also, and some are good on Hub breaker prep .
Get Ready to Rip Your in for a treat Smooooooooooooooooooth and Fast.
