That was me in the parking lot racing. Ran a 10.4 like mentioned above but have ran a quicker 9.88 in the same parking lot ( track was on the other side of parking lot, no sand over there). There was a lot of sand on the track, spun 1st , 2nd and part of third, that should tell you how much sand there was. I never spin third. GS-R integras were running 10.6's and they run alot guicker than that normally. It all depends on take off in the 1/8 not alot of time to make up any mistakes.
Later,
