what lap times are pretty good??
750/600 expert times are in high 30's to win. Winning SV's are between 1:44-1:45
typical trackday times 1:47-1:55
many people are over 2:00 on trackdays.
check mylaps.com and see the CMP WERA event in July for all class times. There was also a smaller event in August on mylaps.
