    I've got a set of Porsche boxster s wheels that im going to fit on my car soon,they're 18 inch turbo style wheels fronts are 7 1/2 inch wide with a offset of et50 and the rears are 9 1/2 inch wide with offset of et52,does anybody know what width adapters I would need I've measured them up roughly on an s3 we had in at work and think I will need 20mm adapters all round,does anybody know if they will be ok or will I need thicker ones

    i reckon at least 25mm. most people get the biggest they can when fitting porsche wheels. its a pain that they are always a stupidly high offset

    Im using 40mm adapters on my S3 with porsche wheels. I tried 25mm ones and the inner edge of the wheel very nearly hit the shocker ( coilover ) i would say 30 mm if your shy or 35 if your looking to turn heads,

    What wheels do you have on yours please mate and what sizes,would a 35mm adapter not be to much for a 9 1/2 inch rear wheel then

    Wheel Offset Calculator
    the above link will help you visualise what they will look like.
    you know how your wheels look now, so if you want the new ones the same, just play around with the ET of the porsche wheels until you have the 'outer position' the same. whatever ET that may be helps you determine what spacers you require.
    be careful of inner clearance though. it would be wise to measure inner clearance now with current wheels, then you know how much space you have to work with when playing with the calculator

    These are mine. they are i think 8 wide all round.
    ET52 . because of how wide your rear wheels are the clearance on the rear suspension will need checking. thats why i surgest such wide adapters. I found the rear archs to be very roomy .

    Ive currently got standard wheels on the car at the moment,I've looked at that offset calculator and will probably be looking at 25 mm spacers for the rear maybe 30mm,for the fronts 35mm or maybe 40mm at a push,will measure up a few things tomorrow to give me a better idea to be able to work it all out properly

    I've worked it out and with the wheels sitting how I think will look quite nice I will need 30mm spacers for the front and cause of the rears being 9.5 inch wide I will only need 20mm spacers
