Hi, I have an MK Indy on standard sierra brakes (rear drums) - currently running 15 inch rims but like the idea of some 13's for slicks etc.

I believe the standard for the 15's is ET38 offset, but if looking for 13's what is the min/max offiset I can get away with without having to d1ck about with widening wings etc.

Also are there any wheels that are known to fit, e.g. fiesta, escort, capri etc?

Sorry this is supposed to be in the MK Forum.

If the 15" rims are 61/2 wide at ET 38 then 13" 61/2 at ET 38 will fit the same.
if you go for 6" 13's then you have 1/4" to play with on a more positive ET ie 6mm or ET 32 for the same outer rim fit
