I'd say it depends on your tech official. The springs are rated at 80lbs of seat pressure. Some techs may give you a certain amount above that, but you need to know what yours does.

@FAH-Q.... spring pressure on a 604 should be around a 100 and they give you around 5 lbs to play with, so 105 Max..... if its lazy off the corner throw some gear to it-put a 6800 chip in the MSD
