How much of a difference do the low friction wheel bearings/low drag seals really make? Looking to make improvements in off season. Have some money, but not a ton to buy anything major. This is steel block, 650hp going against open motors. Can hang near middle of pack now.
If they do make a difference, do I need the super fancy setup with the adjustable sleeve and such from DRP, or will just getting the bearings and seals make a difference?
Worth the money?
