HI,

I have 18 " wheels on my C2, I am looking at 18 wheels from a 997 ( OEM) I noticed the offset is a bit different. The fronts are 52mm and 65mm on the rear for my car. The 997s are 57mm for the front and 58mm for the back. I think this means I would need 7 -8 mm spacers for the back. Is this correct? the fronts will be away from the hub by 5 mm , correct? is this ok?

Thanks

Mike

No - you have it backwards. The 57mm offset will stick out further than the 65mm. Go to the website below and run your own calculations:

You may need spacers in the front.

I looked at the site I think I may have stated it poorly,

my current front is 52mm the 997 is 57mm

my rears are 65mm and the 997 is 58mm

OK - but you still had it backwards. Assuming the same width wheel, the 997 front will be retracted 5mm (spacers would fix that) and the 997 rear will be extended 7mm (spacers would just push itout more).
