84 rear factory spacers?

Trying to find out if I widen a 16x8" Fuchs by 2" to the outside, if it will fit under the stock rear 930 fender.

Is there a factory spacer on the rear (or front) that can be removed?

If it matters, it is on a factory 84 Turbo Look.

I just like to look of a deep factory RSR wheel.

Thx!

I think that is about 1.1 inch.

Thx!

I just replaced the stock turbo fuchs with 18x11 in the rear. I removed the stock 28mm spacer but then had to press in shorter wheel studs from a 964. No problem clearing oil lines or the fender.

Are you going to run slicks? If not, what street tire will fit it?

You are probably asking about the 18's. If it were me I would run Yokohoma ADVAN Neova AD07, Yokohoma ADVAN A048 295/30's ,or a Toyo R888. May of the wide tires are just to tall for me.

As to my 16's, I was thinking of sending in my 8's to have widened on the outside to 10's and run 265/45's Kumo V700's.

Wonder if I remove the 1.1" factory spacers would there be enough room out back to put a 2" wider rim under the stock fender with maybe just rolling the fender???

I want to get as close to a factory IROC look as possible on a factory turbo look chassis.

as I mentioned I went 3" wider with no issues with the fender.
Sorry if I am not understanding your question

Ok, I am not talking about how wide of a rim fits under the fender.

I want to widen a stock 8" Fuch 2" additional to the outside.

By taking the factory 28mm spacer off it will then stick out about .9" further toward the lip. Or, will it go past the lip?

ok I see what you are saying now...I would take the spacer out and remount the rim and measure, check the fender, rotor clearance oil lines etc. I think you might still run into a lug issue as the stock lug is 58mm.

You can always use open steal nuts which are lots safer than the aluminum ones.

With open steel nuts you just have to match up the taper. The Porsche is cupped opposed to tapered. Then you have the appearance factor of the studs sticking out?
Pressing in new studs is a quick and painless job

Sounds like a cool idea!!
I agree with most of the above...

Remove spacer, get your self a few steel lugnuts from a 356, or get a few spare aluminum ones and hack the ends off to open them up. You don't have to "drive" for this test... just mount the 16x8 w/no spacer to try.

maybe cut a long strip of 1-1.5 in cardboard or posterboard, something stiff enough to affix to the tire or rim along the entire circumference... Duct tape or hot melt glue come to mind

Find a place to mount it secure, like, right along the outer edge of the rim, perpindicular to the sidewall

You can make another template of the tire to slide around the cardboard to check clearance in different spots.

Jack up the car on the opposite front corner of the wheel you mounted this crazed contraption on. This will send the tire way up in the fender well, simulating suspension travel on the road more or less.

Definately do it for both sides as the cars are rarely semitrical in that era.

If it works, and you do the wheel mod the stud issue can be solved in multiple ways...

I hope this doesn't sound retarded, I pulled it out of my @ss while briefly avoiding my own difficult technical problems.

Good luck
