6" with 195 tires. Anything wider and you get into pulling/rolling territory ...

I agree with Sir Andy. However if you want a cool looking wider wheel/tire, I have Fuchs 16x7’s front and back with 205x7’s all around. These fit stock fender in front, but do require rolling the upper inner fender lip (with baseball bat against the tire) and pulling carefully (by hand!) the fender out a tad more than just rolling the lips. I had my car raised on my floor jack while making these amateur modifications to the rear fenders.

6” with 195x65x15 or 205x60x15. The wheels are very close in weight but the larger the tire, the more weight and just like a bike wheel, it’s the worst place to add it. I think the two different 5 lug conversions are really close in dimensions but quite different in costs. Do you also want to change brake calipers or leave them stock.

I wonder if I could get 205x60 on my Pedrinis. I’m getting ready to buy tires, and I’d like to buy a tire now for the Pedrinis, that I could later use in the Fuchs.

Do you know if the 5-lug conversions have the same offsets, so to speak, as a full original six suspension?

I’d like to upgrade the calipers. But I don’t know what I’ll go with. I assume that the clearance matters on the calipers?

You can really only upgrade the calipers by using a 911/914-6 front strut and 914-6 calipers on the back. So by the time you do that, you are into it it for more than a couple grand. I can make you up a list of parts needed if you are interested.

I think the bottom line question is how badly rusted is your /6?

I've done a couple conversions, one in 2014 and one now. Old 911 parts are getting more difficult to find and prices are getting higher. Rough price swag:
Front susp and brakes: $1500
Rear susp, brakes, driveline: $2000
Rims / tires: $2500

And you need some skills, especially at the rear wheel bearings.

So, back to your /6...
If it's quite rusted, professional repair, paintwork, and engine rebuild will rapidly get you under water in value. It only makes financial sense if you do the time and the rate of your time is free.

Your best bet may be take all the suspension, brakes, wheels, axles, flanges off your /6 and install on your 72 car. Then sell the remainder for someone else to build a more real GT with better suspension, brakes, driveline, and real /6 VIN.

I have 205/60-15 tires on 6" later 020 fuchs. 914-6/911T struts with alfa calipers and the rear is 911 hubs and vented rotors with PMB "V-calipers" modified 914/4 calipers. This rear setup is a lot more coin as you need 911 hubs, stubs, CV's, input shafts and swayaway axles.

The wife's car has 205/55-15 tires on 6" cookies. 914-6/911T struts with M calipers and the rear is stock with PMB re-drilled hubs. For a street car this set-up is better than needed.

The weight difference between the 15" 5 bolt and 4 bolt fuchs isn't much, I know the 4 bolt are 13lbs, I can't find the 5 bolt weight right now.
Porsche 911 Fuchs Forged 16x6 are 17.0lbs

I’m trying to determine some pieces of information related to putting 5-lug Fuchs on a stock-fendered 914. Any help would be appreciated. Here is what I am trying to figure out:

1. What is the largest size wheel that will fit? Both 15” and 16” 6 inch


2. What is the largest size tire that will fit on the above wheels (without rolling the fender lips or pulling the fenders out)? 205/60 or for the 16 205/55

3. Do the results of questions 1 & 2 change depending on whether one changes to 5-lug by changing the suspension to 914-6 suspension vs. using drilled rotors such as those sold by PMB?
same for the drilled or the conversion. Conversion is pretty good now as it uses genuine 914-6 rear rotors and studded hubs



Anybody know?

EDIT:

4. Are the 5-lug Fuchs heavier than standard 4-lug Fuchs, etc.? I am wondering if they will over-tire the 4-cylinder, and bog it.

Sorry for such detailed questions. I’m just trying to understand what my options are.

One idea - If I can’t find a reasonably-priced six suspension, I’m considering using the 5-lug suspension from my original six on my ‘72 four, while the six undergoes extensive rustoration (likely to take years at my pace).

If 6” with 195x65x15 or 205x60x15, will fit under the stock fenders, will the same size tires, but 16” - i.e., 6” with 195x65x16 or 205x60x16, - also fit? I would think not, right?

If that is the case (that 15” or 16” makes a difference), I need to first decide 15” or 16” it seems.
