Brownstown gears to use?
 

Whats the front and rear sprocket sizes being used at Brownstown In. for a 2008 GSXR 1000 in second gear.

Go on hyper racing and pull up their gear chart....its under tech then gearing....try running around an 11.7 to 11.8 ratio. This chart allows u to match up multiple different combinations to achieve the best performance. I keep this chart in my tool chest, very valuable at the track!
