Sosige,
Yup- the 48p don't come close to fitting(without clicking). I'm glad you covinced me to get a 15X2 motor, this thing is fast-even with the stock gearing. I was going to get the 19T pinion to fit the 58T spur, but at the speed and acceleration it runs at now, I think that would be a downgrade. I've got the aluminum TG10 ssteering rack on order. All I have to do now is soften the suspension and fix the understeer
