My 5.1 came with a 96 spur what size pinion range should i pick up for 17.5 boosted? Or if i need new spurs, is there a type to get? New to pancars. Only just started to figure out the touring car before season ended.
96 is usually kind huge for what most people need in 1/12. The gent above who's 75-80mm rollout is about exactly what I ran on a couple of smallish tracks a year ago.
Use a rollout calculator like gearchart.com. But for example, with a 44mm Rear Wheel, a 76T Spur, and 44T Pinion will get you on the upper end of that rollout range.
