Need help with mounting larger rims

[HamptonT]

My son and I bought an older Go Kart. It has 6" rims all around. The bolt pattern on the rear hubs is (4) 3-1/8" bolt circle. Seems like an odd size. All I can find is 4 on 4" or 4 on 2-13/16.
Is there an adapter plate out there that I can use to get to the 4 on 4?

Anyone know what make/model???

I think you're right. Carter Brothers

It has a 4-3/4" brake drum which I believe is a Carter specific size

Drill

Profit.

I'm serious, by the way. There's really no reason you couldn't take a generic set of 4 on 4s and add a new set of holes offset by 45° from the existing ones, unless you're looking for authenticity.

Yeah. I think that would be the easiest and cheapest option.
