flyfisher 6 2 Cars Posted December 4, 2015 Thinking of fitting a new set of alloys to my cti these are 7 j x15 inch with a e.t of 13 I know the wheel fixing holes are right my problem is will they fit as car has a wider trak 309 Gti rear axle fitted is got 1.9 alloys at present am I right in believing these are 6.5 j I'm thinking may be 7 j is to wide as I don't want to fit wider arches thanks peter Share this post Link to post Share on other sites
Anthony 1,003 Posted December 4, 2015 Standard 1.9 alloys are 15 x 6J ET19 If you've got a 309 beam then I can't see that those 15 x 7J ET13 wheels are going to fit without fouling the outer arches on compression, particularly if it's lowered. It will probably be pretty marginal on fouling the ARB endplate on the trailing arm as well as it'll sit in a few mm further than the standard wheel. Share this post Link to post Share on other sites
Anthony 1,003 Posted December 4, 2015 Further to the above, I've just put the numbers into the WillTheyFit website: The wider wheels will sit 6.7mm nearer to the trailing arm and 18.7mm further out towards the arches compared to the standard 1.9 wheel. Given that standard 1.9 wheels with 195/50R15 tyres sit fairly close to the trailing arm as standard (you'll sometimes see witness marks on the ARB endplate plastic plug) and normally will wear away the very inner edge of the plastic arches with a 309 beam, I can't help but think that you're going to have rubbing issues even with the same sized tyres. Should be alright on the front though, just the rear that'll be marginal. Link here to the site woth the details already filled in so that you can see.
