Rick, that is a great example of why he really needs to look a chassis over close before buying it. A 93 tooth sprocket is great, can’t get much bigger before the sprocket could possible hit the track under tire deflection. I measured my sons ’06 Brava last night in the shop when we were getting it ready for this weekend and it appears the largest sprocket that would fit on his mounted inboard would be about 60 tooth. The rear crossmember on the Brava is at a really pronounced angle, and isn’t far from the rear axle at all. I will be in the shop later this evening and most of the day tomorrow finishing setting up and scaling 4 karts for Sunday, I will measure my Brava, our CRG and OTK Racer and see how big would fit on them.
