I thought they were but I don't see the weld line like I do on the rear. Maybe someone else can verify.

My front fenders are off too. I had to roll the left fender so the 255/40-17 tire on a 9" wheel would fit although I do have about a 1/2" clearance on the inside . The right front fender has plenty of room. I don't believe my car's ever been wrecked.

Can you tell us the backspacing (from the outer lip to the hub mounting surface) of your rims, front & rear?

Also, what, if any, spacers you have.

Well, I just got home and took a quick measurement on mine and my drivers side wheel opening is between 1/4 and 3/8 inch farther back than my passengers side. That answers a question and eliminates a concern I've had, and been baffled by, ever since I brought the car home. I'm glad I read this thread!

The rear 11.5" (12.5" overall) wheels are 7" from the inside wheel half outer lip to the wheel center back face. I believe that works out to a 20mm back space. That spacing is without the 28mm spacer.

The front 9" (10" overall) wheels are 5-1/8" from the inside wheel half outer lip to the wheel center back face. I believe that works out to a 3mm back space. That spacing is without the 21mm spacer so for '80 and later the backspacing should be 24mm.

Thank you.

My car is a 1984, and is actually a factory "Turbo-Look" (M491 option code), not a 930. But, I have been told it has the same fenders, brakes and suspension as the 1986-1989 930s. It certainly has the fenders and brakes.

Unfortunately, when I bought the car it had Cup replicas and so the spacer issue was pretty unclear. It has a rear spacer of 28mm with longer studs, rather than one of the spacers that bolts to the lugs and has its own lugs. In front there is no spacer, although the hub is bolted together as if it were. I have seen pictures of late 930 front hubs and it looks identical in configuration.

The point of all this is that I am looking for 9-9 1/2" front wheels and 11-11 1/2" rears. Obviously, the backspacing/offset is critical to avoid interference with the caliper and fender.

Am I correct in understanding you run the rears with the 28mm spacer on the car and the 21mm on the front and that a late 930 would use the same rear spacer , but no front spacer for those wheels?

Sorry to belabor the point, but I'd hate to buy a set of wheels and find they don't fit.

I think the best bet is to get a wheel set up that uses the front spacer if it has one so that if you convert over to the later brakes or big reds, the wheel spacing will be correct. I'd run with no rear spacer since it's just added weight and with custom wheels they can be eliminated.

With a non turbo car, you may want to stay with 255/275 on 9 and 11" wheels so you don't have to accelerate the heavier tires.

[QUOTE=125shifter;3630923] I'd run with no rear spacer since it's just added weight and with custom wheels they can be eliminated.QUOTE]


Ok.. a little late to this discussion but one that definitely interests me.

My questions are:

- I'm assuming that most here are talking about 17" wheels as opposed to 18"s?

- I have Kenesis Super Cups that were ordered from Wheel Enhancement by the previous owner.. I don't think he optimized the offset as they use the spacers on all corners...

- I want too want to eliminate the spacers/change the offset to get a slightly wider and the deep lip... especially on the rear.

I've got part #s of the wheels, bolt count, and rim half widths written down.. just can't get to it now...

So, has anybody addressed this issue or had thoughts on this using 18 inchers?

Thanks

Yes. I was even thinking possibly 245 in front/275 rear.

Re the spacers - I am just trying to figure out my options in case I find a set of used wheels. If I go with new CCW or Lindsey, I am sure they can provide what I need.

I'm running Kinesis K27 9.5x17 in front with 255's and 12x17 in the rear with 315's. For the track the only difference is I'm running 245 Hoosiers in the front...I have the coil overs so I can't go 275.

Mike, only some pictures to see the distance between the rear flares and the tyres, the look of the back of the car with the 315 and a kind of picture like that.....

Thanks.

I run 9.5x17 front & 11.5x17 rear. Max tire size varies by manufacture. Hoosiers tend to rub a bit more. Front tires are 245x40x17 and rear tires are 315x35x17. I had to remove undercoating in the front and roll the rear fender flares and everything fits just fine.

935Turbo: Looks like I'm running the same size as you.. 225 & 285..

Mine are Kenises Super Cups

- 8 x 18 front... 2 1/4" outer lip, 6 1/8" back half

- 10 x 18 rear.. 3 1/2" outer lip, 7" back half

- Assume 29mm offset? as both part #s end in 29..

- 40 bolts around face..


Again, would like to eliminate spacer and run rim with deeper outer lip. Anyone have advice on who can change/adjust these rim halfs to get what I'm after?

Thanks
