Just won a crt.5 with mikes chassis...did I do ok?

Sweet, thanks for the help! 40-41 on a 14 tooth? Damn those stock tires are pretty short too (cant be more than 3 inches?)

I just looked at the field for circumference and you put in 12.88. I converted that and it comes out to be 4.1 inches. Stock tires are pretty tiny right? More like 2.8- 3 inches tall? I tried checking tower but they only have the width for the stockers.

I would like 40mph to be the top speed (45 is fine as long as im not getting serious heat). Maybe I should swing for the 12 tooth pinion so im safe for the bigger tires?
