The rear tires are 1/8 Parma tires, I hate 'em, I just put them there for the pic. The chassis has 3/32 ballbearings, I will be using a 3/32 hollow axle & some way better rubber, for sure taller & a kool lookin' wheel. So I agree about the tires. Thanx about your comment..."WHAT A BEAST". The motor is from a diecast funny car I bought on eBay a few days ago. Except for that, the body has been interesting, it is resin & a lot of work went into what it looks like now. The chassis is an older DRS model. I'll keep ya posted, check back for more pics. Thanx again, Tom
