If ur chasing #'s.
In my opinion its just a competition build, just for classification. In reality its tooo much $ for high rpm build. Or maybe u got that N/A build bug going.

Dwnshift mentioned that they was changing the stock cranks after every race last year. This year, they're allowed a strong crank. Last year he said the cranks had cracks in them after most races. BUT remember this is on a full flat out racecar, not a DD/track car. For someone like me. This would take the worry out of doing trackdays.
