Stock rims in the rear. My thoughts are with msm's. I'll just sit on them. price i paid was about $40 shipped each, returning them for a narrower and lighter tire would be a waste of money. I also think the weight is really going to bog the carter engine down--pretty much any gy6 i think is going to have a tough time moving this buggy bottom end grunt wise, it's heavy. belt and clutch i think are going to be my main issue. there's a mod in the future engine-wise, it'll find me.
As soon as the yerf axle proves its "history" I plan on a large diameter DOM tube axle. New customer at work yesterday might have the bearing hardware i need to make it work.
