Hi Guys.

This week I will be fitting a set of 20x10.5 Breyton Race GT's to my M5. I was hoping somebody could help with the offset/spacer situation.

The wheels are ET35, I know factory is ET28. An online calculator tells me that the Breyton will give me 20mm less on the inside and 6mm wider on outside. My questions are,
Will I need a spacer to correct the extra 20mm inside or will it be fine?
If I use a spacer will they rub outside as they are already 6mm wider?
Should I be using a spacer to get a better look?

What are your set-ups for your 20x10.5's?

The fronts are 20x8.5, so same width as oem so I'm all sorted on that part,

Any advise would be very much apreciated.

You should be more worried about your front offset than your rear! Breytons are universal cast wheels for BMW cars. Meaning, you need to first check the bore size of the wheel and see if it fits your car. Bore sizes vary between BMW models.

Usually, spacers are provided with the wheels to make them fit your car. However, having said that.. the spacers could possible be hub adaptors instead of regular spacers.

I have Breyton Race CS wheels on my car, I used the 18mm spacers that were provided with them for the rears, the front offset was ridiculous, I had to install 30mm H&R spacers to make them sit better.

Thanks for your reply, your thread was really helpfull.

I should have made myself more clear on the fronts, I had already calculated for a 30mm adapter on the front, that bit was easy as both the stock and breyton is 8.5.

I was hoping to find somebody with a 10.5 rear....

Wheels are finally on, I thought I'd post the sizes of tyres and spacers I used, plus some pretty bad pic's from my phone. I'll take some better ones if anybody wants to see.

Front 8.5x20 et35 with 30mm spacer (et5, factory et12) with 255 35 20 PZero
Rear 10.5x20 et35 with 10mm spacer (et25, factory et28) with 295 30 20 PZero
