Does anyone have one?

I want to do a Truggy conversion around my birthday since I'll finally be able to get a job to help fund everything. From what I've read this is just the Race Spec Roller so it has some lesser quality parts to keep the price down. Does anyone know what those parts are and if they would cause a problem bashing?
