B3 and B4 Rear rim's. Is there a difference

[JonBoy]

Hey i have a used B3 and i belive it has B4 rims on the rear. Is the offset different between the B3 and B4 rims?

Yes they are different. I use B3 rims on my B4 right now because the Proline's (the only B4 replacements rims I could find) wobble like eggs. I believe the B3 rim offset is 3-4 MM towards the outside. In other words, B3 rims on a B4 end up making the buggy wider.

thanks thats what i was thinking, I belive i have b4 rims on a b3. Its pretty narrow.

so, B4 rims fit the B3? i thaught you have to have B4 hubs!
