Porsche wheel offsets

[cupralooks]

Hi All I am looking at a set porsche cups that are:

17"x9" ET 15 for the rear and
17"x7.5" ET 23 for the front

I was wondering if they would fit a mk3 ibiza???

I know that I have to add adaptors as well which is going to push the ET down even more and I was wondering if they would stick out to much??

Kind regards,

Alex

They won't fit, you need to be looking at offsets around 52 or 55.

use this to work it out. http://www.1010tires.com/WheelOffsetCalculator.asp
the original cupra alloys are offset 37 and think they are 6.5 inch or 6 not to sure. but you will have to take your adaptors into account as well.

mine are d90s with offset 52 7 inch wide and i have 40mm adaptors on the rear to stick them out enough

I think the recommended thickness is 20mm (each) for porsche adaptors, so if you get a rim with an offset of et55 the offset will become et35.

Ideally you need four front wheels: 17 x 7.5 inch et 52

So I need to got a set of wheels that have an offset of around ET55 on both the front and back???

I have seen a set with the rear wheels that are 9" wide with an ET of 70, is that too high??

Cheers

An offset of ET55 would be ideal, ET52 would also work but ET70 is too high.

Ok, Thanks for that, I will have a re hunt around and see what I can find
