rubbing on full-lock is not a problem. just be a little careful when parking.

I could live with that (although I have to do a 4 point turn to get in/out of my garage as it is) but it doesn't solve the ride height - the car at present looks more like a tractor

I dropped off the wheels yesterday and am hoping it's a simple mistake. Both front wheels have been over stamped (ET 50 with 47 stamped over the top) and both rears have no stamps but the offset (ET 47) has been etched into the paint - both a little unusual so they need to get to the bottom of it.

I'll have to wait and see but thanks for all the advice/help

FYI - you can get a washer/ spacer to go on the steering rack rod end on each side that will reduce turn radius, stops rub on inside.

I have 18s on my car. Not sure on the tire size on the front but I have 295/30/18s on the rear. I have coil overs on the car and I had to raise the rear so it would quit wearing the insides of the tires fast. I also had a good alignment done and havent had any problems since. My fronts have never rubbed though

Yea, those 18" Turbo twists should have a comparable offset to the Cargraphic wheels (assuming the fitment apw2007 has is what is quoted online). The twists are probably 18x8 +50 in the front. That shouldn't be too different from a +47 or +45 wheel. That white AP Car Design car we all drool over runs a 18x8 +45 w/ 225s.

There's some discussion in this thread (scroll down slightly) regarding rubbing in that area you mention and how to address it.

Did you ever get this fitment sorted?

sml

with which part of his problem?
i thought we knew the answers to his problems anyway?

the rubbing on the front guard corner was definitely the caster.
the offsets are easy to calculate with know good fitments.

Update: I put my winter tyres on in November and left the car with Parr to try and get to the bottom of what was wrong. Everyone seemed to have differing opinions so that in the end I was sure what the outcome was going to be.

Cargraphic didn't want to take the wheels back because they said they were the right wheels for the car. Parr tried them on a 964 RS (different suspension) and there were no issues. Next they tried them on a 964 Cab and again no issues (although the car was LHD and it's early history was unknown). At this stage it was starting to look as though there maybe something wrong with my car - not what I wanted to hear.

Parr were caught in the middle and asked me to be patient as they had a customer with a 964 C2 and they had serviced the car from new so the history couldn't be any better. The car finally arrived in their workshop 3 weeks ago and the wheels didn't fit. Big sigh of relief all round!

Parr then tried fitting 6mm spacers to the rears and 3mm to the fronts and no more rubbing. They tried them on my car in a week later and it seems the problem is finally resolved.

Cargraphic say that they have supplied these wheels to customers in the USA (but I don't know how many so it could have been 1) with no issues but have now accpeted that they not suitable for my car. The wheels are now back in Germany and hopefully they will be back next week with different offsets and after the 'geo' has been done, it will be happy days. It's been a long haul!

well i am officially confused!
your original issues are quoted above.
you solved the problems by fitting spacers.
this does not make sense.
i think there are some communication issues here.

apw2007

You forgetting it's a 3 piece wheel so they fit the spacer between the centre and the rim which moves the rim (and tyre) inwards- not between the wheel and the hub if that makes sense. I posted a picture which is on the previous page

sml

yep makes sense ....... we have all been talking about different spacers from the start!

would be good to get to the real source of the problem .. the stated offsets should be fine.

why don't you measure the offset of the wheels if they are off the car?

apw2007

We did, the standard wheels for the 964 C2 have a 53mm offset and the ones supplied by Cargraphic had a 47mm offset but we were told these would fit. The fact my wheels were over-stamped turned out to be a 'red herring'. When the wheels are returned the offsets on the rears will be 53mm (standard) and on the front 50mm (the 3mm will allow me to fit bigger brakes).

Because the cars were made 20 years ago there is not much technical information available so it's difficult to establish why the wheels with the 47mm fitted some 964's and not others. The tolerances on these cars are very different because they were assembled by hand which maybe the cause but I doubt I will ever know for sure.

I'm grateful that Parr persevered and that Cargraphic have agreed to address the problem so although it's been very frustrating I will finally have the car as I wanted it.

sml

same width?

apw2007

The tires are 20mm (approx 3/4") wider on the front and 40mm (approx 1 5/8") wider on the rear and big difference on the rim width

Original wheels
Front: 6 x 16" 53mm offset with 205/55 R16 tire
Rears: 8 x 16" 53mm offset with 225/50 R16 tire

Cargraphic wheels
Front: 8 x 18" 47mm offset with 225/40 R18 tire
Rears: 10 x 18" 47mm offset with 265/35 R18 tire

Cargraphic wheels - replacement wheels
Front: 8 x 18" 50mm offset with 225/40 R18 tire
Rears: 10 x 18" 53mm offset with 265/35 R18 tire
