offset on a 13" rim?
daniel mason - 18/1/10 at 11:14 PM

what offset does a 6" wide 13" rim need to clear the standard sierra front calipers?
and a 7 1/2" rear rim to clear the sierra handbrake caliper? cheers!

I think it's more to do with the design of the wheel than off-set. Do you have a make and model in mind?

Is this in relation to the MNR? If so, I can help... but they aren't Sierra front calipers so I'm guessing you may be referring to another car?

If you re-read my post, you'll see that I refer to your front brakes only; I'm well aware that you fitted Sierra rears.

Compomotives will give you as good a chance as any. You also need to think about the position in the rear arch.

sorry mate never read the post properly! would imagine the et38 rear would be ok but et19 front am not sure?

ET13-19 is normal on a Cortina set-up but I dont know for sure about Sierra.

Ask a direct question in the running gear section, or see if there are old posts in the MK section about 13" rims as they use Sierra gubbins.

i would be on cortina uprights but to keep costs down i was going for sierra calipers, or any other which will fit and do a good job of stopping the car, a second hand pair of R16's or wilwoods is an option also
