I would guess it’s worth between 2-5 tenths at Pitt. If you want to have lower maintenance but some of the performance advantage just slip it a little lower. 8200 would last a long time. Just need to remember to lube the bushing with tri flow every session along with the chain. Another thing to be aware of is don’t start your engine until youre about to pull onto the track. Also, don’t abuse your clutch on the pace lap before the start. The majority of clutches get far more abuse in these instances than the do throughout a whole race.
