What size Fuchs came on 1987 930

[mclmk8d]

On my 87 Carrera, the PO rolled the front fenders, lowered to Euro height. I'm running 7s and 9s with Bridgestone RE-11s, 225/50-16s in front and 245/45-16s in the rear...absolutely no rubbing

[Patrick 87 930]

Note: current wheels are some flavor of turbo twists not sure the width.
Rear tires are Kumho Ecsta 275/40ZR 17 (Rears have a spacer
Front Michelen HX MXM4 235/45 R 17.

OK I am torn now on the wheels and there is another tread on here with a few great looking wheel and tire setups some Fuchs and some after market.

Correct wheels for the car are not going to get easier to find nor do I expect them to get cheeper over time. I think I'm going to wait till I find the right price for the correct matched set of wheels ie 7s and 9s and buy them so I'm covered in the future if I decide to go orriginal. Then also track down some 8s for the front. Most the posts in these threads say the 8's will handle better. I assume I may hit some problems getting all the wheels to match in finish. Oh and the cost may guide me considering I would be sitting on a set of 7s wheels and tires. Decisions, Decisions LOL

Full wheel well without rubbing with great handeling is a goal. I do throw my 11 year old in the back seat sometimes. The backs don't rub now but the fronts do. Front left hits the water bottle and I think that plastic is getting a little thin. It also hits the rear of the front well and that has rubbed to the metal. Aslo just found the washer fluid line had been rubbed clean thru, I guess it hung down a little and rubbed. So I'm on the hunt for some of that Black and yellow tubbing I assume is original with only 72K miles on the car.

One more thing to think about. The offset on the wheels you have now is quite different than stock. Ordinarily, spacers are added to compensate. Done right, this involves changing the wheel studs. Done wrong, they don't do this and the lug nuts are a little short on engaged threads. You might have a look at what spacers and lug studs are on there now.

The best solutions for matching the finish on wheels are:

Buy new ones.
Buy old ones that need to be refinished (don't buy bent or chromed ones) and send them to Harvey Wiedman to refinish together.

JR no need for the 944 wheels - this is a 930 - plenty of room for the 911 offset

I know, I've owned and driven 930's for 30 years. Still, I like the 951 8's because they look stock, more or less. And I like keeping the same offset as the stock 7" wheels, from a steering point of view. Plus a 930 could use a little more track width in the rear, so I'm not a fan of the 911 8's on the front, just from an appearance point of view. Not to mention, it adds to the sandblasting of the rockers.

Not my car in this case, so I suppose it doesn't matter...

Hmmm, I wondered why 951 8s were so expensive in comparison to 911 8s. I always thought it was because you could get bigger brakes under the 951 wheels as opposed to the 911 wheels.

BTW, 951 8s go under Carerra front fenders OK with some of the wider 205 rubber. Crazy at-the-limit cornering can give some small rub.

I plan to roll the front fenders so I can get 225 rubber under there, but I don't think you'll have trouble with 951 8s and 225 rubber.

Supply and demand?

You can get bigger brakes under a 951 8" wheel, not that that is an issue for a 930, as those calipers will fit under a much smaller wheel anyway.

I could also say that it's not an issue on a 911 either, which doesn't need brakes bigger than what will fit under a regular 911 wheel, but that's beside the point, right?

I wouldn't run a 205 on an 8" wheel.

Normally, I wouldn't either. But when I was looking at the tire, I noticed it was pretty wide. Wider by A LOT than the 205 that was on the 7 on the car.

So, I had the tire place put the new 205 on the 8. And there is significant rubber bulging past the rim. In fact, it looks almost the same as the previous 205 looked on the 7 that had been on the car.

Standard sizing really isn't. I knew already that Kumho rubber ran a little wide. It also runs a little short. IOW, their 50-series rubber is almost always smaller than 50% of section. I have a bit of experience with Kumho rubber, since most of the vehicles in the fleet around my house wear Kumho. The Fuzion tires that had been on the 3.2 might also have run narrow.

All good information. I'm trying to soak it all in to make a decision. The rears do have spacers so what length stud did it come with ? I will need to pull the wheel and take a look. If I do need to revert back to original are they just hammered out or is there more to it?

[javadog]

The rear would have had a 28mm spacer on each side. The front would not have had one. I don't recall how much exposed thread there is on the studs on either end, but it is enough to come close to the depth of the stock aluminum lug nuts. Changing the rear studs is a difficult process, because of the wheel bearing arrangement used on the rear of a 930.

Hmm so the stock 9 inch Fuchs for the rear still used a spacer? Here is a picture of what's on there now. This is offset so much it just looks odd. Here is a picture. I will need to measure what size picture is on there now.

[Patrick 87 930]

It measured 22mm

Yes. 28mm thick. Part number 930.331.611.04. If yours are 22mm thick, they have been changed. Pull a lug nut off and see if the studs look like they have been cut.

Are these 87 930 wheels or 86
Here are some more photos.
The part # on the 7 X 16 is 911 361 020 44
The part # on the 9 X 16 is 911 362 119 00
I see a stamp inside the wheel that says 49 86

[Patrick 87 930]

Are these red rims real Fuchs and are they 1987 930 correct

[A horse with no name]

Will 9" fit on a Carrera (rear) or are they just 'tooo' wide - Thanks

If the wheels have that stamp, they would have been made after Porsche changed over production from the 1986 model year to the 1987 model year, so I would say that they would have been fitted to a 1987 model year car.

When I was looking for a set of 7s and 8s I was surprised to learn that not only would the 9s fit on my 3.2 Carerra, but that my local dealer could get them for me brand new. If you're having trouble finding 9s might be a route to check out.
