Didn't look like much drifting to me. I destroyed an R6 at Gingerman with inside wheel spin from the damn VLSD. I scrubbed the rubber off the inside shoulder of the inside tire.
I put a NISMO diff in the race car though.
I think you can pick up a good bit of time by taking 10 tighter and carry more speed and go wider on exit of 1. Looks really nice through 5 and 6.
