255 Rears With Adaptors

[S3Hendry]

Purchased lovely set of twist alloys but not sure what thickness of adapters is suitable. With the rear tyres being 255/40/17 I think with 25 mm adaptors it would just be too wide, according to my tape measure. Anyone got that set up?

15mm adaptors are prob the way ahead but then the m14 1.5 bolts are too long! ***!

I know there is a few folk on here with porsche alloys, so please take a moment to help this headless chicken!

Nearly forgot, I own a 2000 s3

Do you think getting a engineering specialist to machine the bolts down to the suitable length would be safe?

As long as they use plenty of coolant so the don't warm up whilst machining them then they should be fine to be shortened. The cost would prob be the same as buying a new set of bolts tho.

Yeah I'll see what happens when my adapters arrive, maybe just DIY. Wheels stung me bad enough, then again don't think I got the worst deal. Moving on to other issues, as I already said rears are 255 but the fronts are 205! Jeez I'm going straight ahead on every roundabout!

I run 255/40/17 all round. Up front it's pretty tight and does rub (something I need to sort). 245s were fine as I run 2.5 camber and the H&R clubsports are super firm.

I run ET15 front (to clear brakes) and ET20 rear. Could probably get away with ET25 rear but I didn't want it too far off the front.

Front does poke a bit (hence the odd rub):
