HELP . . . WHEEL ADAPTERS . . .4X100 or 4X101.6?

[werthie]

following up on my last post . . .

 

i've located four (4) used (but nice) 13X7 Revolution wheels, but they're for a Sprite/Mini, so the bolt circle diameter (PCD) is 4" or 101.6mm.

 

am i OK using a wheel adapter with a 100mm PCD? there don't seem to be any 4.25"/108mm adapters that are specifically for a 101.6mm bolt pattern.

 

also, the minimum adapter thickness is one inch, or 25mm . . . if i can find (or have made) the correct adapter, what range of backspace/offset do i need, so the adapter, wheel and tire will fit under my fenders ('92 S3 Caterham)?

 

sorry for all the questions, but the wheels are out-of-state, and if i buy them, there's no returns.

 

many thanks!
