[Guest]

Hi,

Can someone please confirm the offset for a 91 C2 964

Thanks

Pete,

Assuming it's a standard narrow body the standard offset both front and rear is 52.3mm

Thanks Dave I new you would have the answer![]

It depends a little on the WIDTH of the wheels rather than the diameter. If the rears are 9" or wider you may need a small spacer.

sorry forgot to mention that the fronts are 8.5 and the rears are 9.5 width

Shawn,

On a narrow bodied car I suspect you'll have contact problems on the front with 8.5J/ET52. Even with 17"/7J some cars have problems so I suspect you'll need at least 5 or 7mm spacers. The bigger 10mm steering stops might help but they will restrict the turning circle a fair bit. The 9.5J rears would ideally be ET47 so the same spacers would suit there too.

Hope that helps.

Chris,

Although an 8J ET47 wheel is a little unusual at the front, it's not so extreme as to cause a problem. On another thread there are some discussions about some wheels from AP Design which are ET42 and they seem to fit OK although I'm guessing they may roll the arches to cope. I'd expect a more "normal" front wheel to be something like an ET52, so you're only 5mm further out and I really wouldn't expect that to cause a problem.

I agree with Dave, I have some 8j with a ET42, but are a but pokey than normal, just fit, but with look and tires I would prefer a little bit more inboard with a bigger offset.

Thanks Guys

I guess that you have confirmed what I thought. the front looks just a little strange but it will work, and the rear is more or less spot-on.

Thanks again to you both.

I hope that answers some of the queries Chris.


Dave, I was offered a set of 18" Techart wheels, but had the offset of ET40 on a 8j and Et 60 I think on a 10J, this wont defo fit on a 964 will it?

Norm,

I would guess that the fronts would be very marginal although you might just get away with it if your arches are rolled. The rears are close to the Turbo 3.6 fitment (ET61) but you could, of course, use spacers with those. Something like 13mm would put it right.

Thanks Dave, keep you updated!
