Hi all

After spending hours with various offset calculators I'm almost there, but would really like someone's advice, who's done it:

I've just bought a set of Carrera III alloys:
Fronts: 8J x 18 ET 57
Rears: 10J x18 ET58

My current Turbo twists are:

Fronts: 7.5J x 18 ET50
Rears: 9J x 18 ET52

The car is a 2001 Boxster 986 3.2S

What I'm trying to work out is the size of Spacer required at the back - I currently have a 22mm and whilst it easily clears the strut, the tyre does stick out of the arch slightly.

The research I've done suggests a 15mm or an 18 mm spacer will be perfect, but not having the luxury to try before I buy I don't want to make a mistake and I'm finding mixed results re. rubbing - whilst the 18 will definitely work, will the 15 tuck in slightly without rubbing on the strut? I'm getting confused!

Cheers

11 mm would be ideal I believe. The 986 with an 18 x 10 should have a 47mm offset, at least that is what I came up with. So the 58 should be perfect with an 11 mm spacer. 22 would definitely make it stick out a little. The 22mm spacer would make an 18 x 11 work nicely I think. If you decide to get smaller spacers I might be interested in your 22s.

I run 10"x18"ET58 w/295/30-18 and 18mm (equals ET40) spacers from FVD. The tires are just flush with the fenders, absolute no issues.

Not to high jack the thread but I just came on to ask a similar question. I want to put... Fronts: 7.5J x 18 ET50
Rears: 9J x 18 ET52 Turbo Twists on a 2001 and was wondering what spacers to use. From what I understand you only need 18mms in the rear. Is that correct?

Thanks
Tim

With 9"x18"ET52 and 265/35-18 tires, you don't need spacers. They will clear the strut towers/coil springs with 5-6mm.

Thank you Fly -just what I was after. So with a 22mm I'd need a fender roll...

Would it be useful/possible to make a template spacer out of 3/4" [19mm] and/or 1/2" [13mm] wood or aluminum? Test for fit/rubbing, etc. If wood, can plane it down some, and test again.

Obviously don't drive on them ...

LOL - will report back
