    Hi guys,

    I know this question has probably been asked numerous times but i could not find anything through the searches.

    I have a friend with an S3 who wants to swap his S3 wheels below:

    He wants to swap them with my wheels the RS style below:

    If i am not mistaken my wheels are 8.5 or 8.0 ET45 However i have no idea what the width or ET the S3 the wheels above are ?

    I am planning on dropping my car 50mm (Sline suspension) and spacing it out 10mm Would encounter any rubbing issues ?

    Thanks in advance

    Should be ok. S3 offset is ET45-55 taking it to ET35 may have some issues so I would get a stretched tyre and remove the rear bumper screw at 2 o'clock if you are facing the arch.

    Think up to 9" wide is accepted.

    S3 wheels are 7.5" wide, and ET54 or 56 (don't remember which is pre-facelift and which is post) but either way they'll fit. Assuming you have an A3/S3, any wheel that fits your car will fit his car the same and vice-versa.

    Use Wheel Offset Calculator to figure out what spacers you need to get the same fitment for each wheel.

    Depends whether he goes genuine or aftermarket and what the sizes are.

    What sizes/offsets etc are the other wheels do you know? If they are S3 then of course they'll fit.

    Why do you plan to space it out 10mm before knowing the width and offset of the wheels? Seems a bit of an odd time in the process to make that decision.

    A lot of S3s run 10mm front and 12mm rear spacers though (without any rubbing when I put my H&R springs on with stock wheels).

    Terrible photo, but you can see how S3 wheels sit at ET46 front and ET44 rear -

    Thats a good point! I just always had it set in my head that i would need to space them out. No idea what ET the other wheels are but they are OEM S3 alloys so they will presumably be 7.5 I have seen ET33, 42, 54, 56 all listed so i have no idea.

    But as long as there are no issues with rubbing once dropped then i have no problem swapping them.

    Would you suggest going with a 215 tyre ? and removing the arch screw just as a precautionary measure ?

    Please do feel free to educate me if nothing i say is making any sense ?

    Mine only rubbed on the rear when 5 up, and 2 of the 5 were ~100kg each. Unless you're going very low, or very wide, a 225 will work fine.
