Small update for today. We finished up the programming on the spinning machine so that we will now have a proper shaped and profiled outer wheel shell.

Hard to explain in words, but suffice to say the outer shell will look "fuchs" and not "3 piece wheel"

Cheers
Glad to hear about your bill of health!

As for your description of the "new" Fuchs, I think I get what you're saying. For those of us interested in the 9s and 11s (17"), will this "ramp" still allow for deep dish?

Yes, this has no effect on where the center of the wheels sits vs the outer lip of the wheel.

Cheers

Hey Jeff,

I am little late to this topic, but am interested once I wear out my SO3's. Can you post/email/PM your pricing? I'm running 7&9 Fuchs and love the monochrome and original look.

thanks

What is different about the early and late turbo fronts? I have a 1976 930.

Are early and late turbos the same in the rear?

Late turbo has the spacer incorporated into the front hub and requries 21mm more offset.

I would need to check on the 76/77 cars. I know the 78-89 cars are all the same on the rear.


Cheers

Jeff,

The choice to go 11.0 or 11.5 on the rear of a turbo (in my case, a '79) - is that purely up to one needing to roll the fender? Or can one get away with an 11.5 and appropriate rubber (315's?) without fender rolling? Would you recommend max 315's for 11.0 and 345's for 11.5, or something else?

Cheers,
Rob

11 or 11.5 really does not matter much with a 315. Every one of these cars are different and each car can be different from side to side too. We have seen 1/4 inch differences in clearance from left to right on the same factory never hit car.....

One of the fastest track guys I know runs 275/245 while most prefer a 315 rear with a 255 front. I don't own a turbo bodied car anymore so I have not done any testing with different tire sizes to see the difference though...

Cheers

I know there is a certain "WOW" factor with the wide tires, but for my daily driver sled, do I need to run 315s on an 11" wheel? Or would a smalller width tire - 285 for example - require too much stretch?

Sand, I have 285 on a 10" x 18" rim and it looks nice and tight, I think an 11" wheel would be too much of a stretch but as we know different models of tyre have slightly different widths despite the number.

I will add that 275/245 is honestly as much as you need on the street unless you are packing big horsepower.

Anything larger is cool but not really needed in many cases...

"Need" is not a word to be used in the same sentence as "930".
Smaller tires/wheels reduce unsprung weight increasing the nimble handling and quicker track times. They are cheaper too.
For the other 90% of the turbos that are not often tracked wearing 9.5 & 12s with 275/345 is just plain badass.

i believe i have 235/275 on 9 & 11's.... but the stretched look isn't the best IMO... in fact i like the slightly bulged sidewall...

Well I guess what I was getting at is that I prefer to run the smallest width tire possible, that will safely fit an 11" rim without an overly stretched look. I mean if I have to run 315s so be it...

The smallest tire width on an 11" rim with no pucker, in theory, would be 305mm (if taking for granted that an 11" rim is actually 12" wide).
In reality you have to check tire manufacturers to get the actual section width. For example, a 295 BFG is wider than a 315 Pirelli. The 315 Pirelli will fit flush on a 10.5" rim!!

Many thanks, Brian!!! I know you have a wealth of knowledge in this area!!!

If you get 11"s, maybe you can try some really low profile (read competition) tires to get a smaller and lighter tire on a bigger rim??? They ought to have the most width out of any tires per size. Just a theory.

Remember that a smaller rolling radius tyre will also give you a smaller contact patch. 935 Norbert Singer.

It will also lower your gear ratio slightly the smaller the rolling radius and make it more like a 16" tire for 'gearing' effect. Or sort of in between a 16" and a 17" anyway.

Even though my degree is in accounting, boy I wish I would have paid attention to those Catholic Nuns trying to teach me math and science, back in the day!!! I feel like a dumb blonde (even though I have black graying hair) when it comes to gear ratios and such!!!
