    what adapters will i need to fit bmw M3 wheels to my s3?

    I have some spare M3 wheels (sold the car) that i would like to use on my S3, since one of the current wheels is broken beyond repair :S
    I think the M3 wheels should have those dimensions
    18" x 8", 5 Lug, 120mm Bolt Pattern, 47mm Offset (Front)
    18" x 9", 5 Lug, 120mm Bolt Pattern, 26mm Offset (Rear)

    What will i need to make those fit?
    here are pictures of the two cars in question

    With the fronts, you can run ET20-35 with 18x8, you are going to struggle to squeeze the rears on if they are 9" wide and ET26. I'm running 8.5" wide ET 20 on the rear, I reckon I can go ET15 on an 8.5" rim before it touches, running 235 tyres.

    planning to run 225/40/18 (same tires i have currently on the S3) but on the M3 wheels.
    But have no idea which adaptors size to use:
    if i take 16mm adapters at the front and 10mm at the back will it fit?

    those are the adapters in question right?

    Nooo, you need hub adaptors! 5x100 ---> 5x120(I think that's the BMW stud pattern?) ones, And I think they are only available in 15mm or 20mm minimum.

    Just to give you an idea, this is how 19x8.5 ET20 sits with 235/35 tyres, so even with a 225 tyre stretched on the rim, I think the rims are going to poke out the arches, unless that's the look you are after?

    The rear offset of the BMW rims are VERY low, the lower the offset, the further out the wheel sits from the hub.

    If you go with the wheel adaptors as posted by Dane below,

    These are 20mm wide, which will make your BMW wheels offset ET6(it's actually ET-6(minus)), and with the added width of 9", they will poke out of the wheel arches a lot in my opinion.

    I just bought some adapters to do exactly this (5x120 BBS Rims on S3) and got them from motorsport tech:
    Wheel Adapters, Wheel Spacers, Hub Rings, and much more! | Motorsport Technology

    Cost me about $400 for all 4 hubcentric to wheel and hub including all hardware and shipping. The dude that runs the company is really helpful and will work to your specs. I went with 15mm (F) and 20mm (R) giving ET20 and ET15 respectively. I'm fitting 18x8.5" and if my calculations are correct it will fill the arches nicely

    thats cool! My problem is with the rears as they are 18x9".
    And 400$ is too much for just fitting a spare wheel of bmw onto an S3, i rather sell my current S3 rims and the M3 rims and get a nice set for the audi.
    Ill contact them see what they have for me and at what price
