Everybody needs to remember that 1977 Paul's yellow 911 does not have SC/Carrera flares (the flares began in '78) and therefore the 16x7 wheels will fill-out the rear of the car MUCH more than a 78-89 911. That's why the recommendation of spacers or bolt-on adapters is mentioned for the flared 78-89 cars- because 16x7 up front creates a wider front track and the rears still have lots of room to move outboard because of the much larger SC/Carrera flares. Spacers (or wider 16x8, 16x9 wheels) help fill-out the wheel arches better.

Also, if you have a pre 74 (I think) the flare, such as it is, is actually slightly less than the later S version.

Paul brought up something I wasn't aware of--that is, rear flares from 69-73. I had assumed they were the same as those on 74-77 cars. I've had 69's, 73's and a 75, but not concurrently so I can't compare. Can anyone confirm if the flare is a bit different between pre and post 74? If it is, it must be very minimal.:confused:

Since I don't track the car anymore, I was more interested in how it looked on the street than how it performed on track. I set it up so the rear is @ the same ht as the tire dia, which means it is actually about 1/4" or so above the tire since the tire flats a little on the bottom. Then I set the front 5/8" higher which gives it a slightly nose down attitude.

AFAIK the Fuchs 16x7 only have one offset. I think The 8s have 2.

I still have some room in the rear so I think I'll add 6mm spacers @ the rear next spring. I'll just have to try them and see if there is any rubbing.

The lips on the srches are stock; not rolled or trimmed.

What tires are you using? I went w/ the 50 series because I like the look and the change it makes in overall gearing. Again, since I'm on the street , I like the better acceleration @ the sacrifice of overall top end. Remember, different tire brands can measure out differently despite having the same spec. A wider tire may cause a problem, but I don't know @ which point this would occur.

Also, if you have a pre 74 (I think) the flare, such as it is, is actually slightly less than the later S version.

Thanks for your kind remark.

Hey Paul, its late, and I am not sure on brand, but I am running 225 50 16 and I rub. Mine is a 76s, with chrome around the arches. I will remove the chrome, but my car is at stock hight, and i rub around corners, or with a passenger. The picture looks like your rear wheel is tucked behind the wheel well and lowered. I really love the look, but i rub without lowering the car. I have 6x16 up front, and would like to run 7x16 eventually. I'm new at all this, so it will take time to understand all the cool things to do. Making mine look a little like yours is top priority. Here is pic of mine with the 16's at stock height[

I have room, but the tire sticks out just enough to rub over bumps, and turns

Will attempt to upload...77' 911S with 205X55/16. Stock suspension for the Colorado back country....

I have some spacers leftover from the previous owner that I will probably throw on, I think they are 8 or 10mm. I have been thinking of larger spacers but was avoiding restuds or lip rolling. How necessary running all 7s.?

my1st911,

My tires are 205/50 so they are approx 3/4" narrower than yours. Your tires are also about 3/8" taller. That, coupled w/ the characteristics of the particular brand of tire, may be enough to cause the rub.

Your ride height seems more than sufficient to me to allow for clearance, though. In fact, from the pic, it looks like the center of the arch is at least 1 1/2" above the tire. I'm wondering if there is another issure here, like worn shocks or worn rear suspension bushings, which are allowing the body to fall onto the tire under load.

OregonCab,

W/ 7s and the same sized tires all around I think the rear track may be SLIGHTLY smaller. Whether this is problematic, I think, may be down to driving habits and car usage. The LOOK would be greatly improved by using the spacers to fill out the arches. Most likely a wider rear track would allow less oversteer and/or improve turnin.

Aircooled911 has what I felt was the max dia for 16x7s on mid years; namely 205/55. I wanted to go slightly smaller (50) so I could go lower w/o issues.

Ossiblue,

As I wrote, I think that is the case re flare sizes. If someone knows this is incorrect, please let us know so w get this right.

Remember, what I did is what I feel is a good aesthetic approach, especially for the type and location of driving I'm doing. If you are tracking the car you may want to explore other options, such as wider rear wheels, larger rear tires, welding on wider flares, etc. As KTL points out, SCs and Carreras already have wider flares, and can accommodate 8s on the rear, although the original post by mnmasauto referred to 7s on an earlier car.
