from what I know, the original 916 had 7x15 Fuchs with 185/70-15
what about wheel spacers ?
or - what offset do this 7x15 have?
is this enaugh to fill the fender flares?

I mean, the M471 cars had 6x15 with 185/70-15 and used 21 mm wheel spacers

who could tell us more?

Gustl,

I been meaning to post this pic of the Brumos/Hussey 916 so you could see it. I took this shot myself at Daytona in 1981 at the IMSA Finale race. The car was owned and driven by Bob Snodgrass at the time.

Notice the "BOBSLED" license plate.

thanks Paul, great shot

but, the question is still the same ...
what rims exactly?
did they use wheel spacers (and if - witch ones)?

G-
on my clone I'm using 15x8 in the back w/ 225/60HR15's, & in the front I'm using 15x7 w/ 215/60HR15's. I did not have to use any spacers in the back to fill out the flares, but in the front I used 21mm porsche spacers, off of a 944, w/ 65mm wheel studs. All wheels are genuine Fuchs, however I have no idea what the offset is. These filled out the front flares nicely.

thanks Al, but as you know, the original 916 setup included only 185/70 VR 15's all around
those are 40 mm (30 mm) smaller each

and - what breakes do you use?

and - what rims exactly do you use?
all of them are 7Jx15" Fuchs
911 361 020 01 => ET 23,3 (light weight)
911 361 020 41 => ET 23,3
911 361 012 05 => ET 49


as you can see ... questions over questions ...

G- I checked the backs to make sure they were all Fuchs & the part #'s are 911 361 020 41 in the front & 911 361 020 42 in the back. I had all 4 wheels refinished & sold the ones that came w/ the car. They were the same size as the ones I got off of the 944, only oxidized & pitted. Yes, I know I have big fat rubber & I like it !! Brakes are mid 1970's 911S in the front & soon to have Erics' GT converted brakes in the rear. Right now the rear brakes are stock 914-6 units.

7" back in the day would have had to have been the 7R would they not? (911R offset)

I don't think so. I think by '72 Porsche was also working on the street 911RS which used a 7x15 rear, 23mm offset and 6x15 front (for most configurations)

Plus, the 911R 7x15 would have a 49(?)mm offset and wouldn't have needed flares to begin with (except for perhaps racing homologation purposes).

911 7x15s use a 23mm offset which makes them rub the outside of stock 914 fenders, thus Porsche's use of flairs. I do not know if spacers were used. I wonder if Ludvigsons book mentions it...

Looks like the "brown" one has 8 or 9x16s on the back.

Looks like the Brumos/Gregg/Hussey/Carlson car has upgraded wheels.. they look like 7 and 8s front/rear which would make sense to an enthusiast to put on even larger than original ones.

Lugvigson, in Excellence was Expected -(pg 594) says this:

7x15 rims all around
185/70-15 Michelin XVR tires (although the pic looks like XWX's )
Spacers: 21 mm front and 27 mm rear

The only profile picture of a 916 shows what appears to be "deep 6's" or more likely, 911R style 7x15s. They do not have a "lip" or "dish" like subsequent 911 7x15s

Also, the flares were based on the GT car, whose flares would have been sized for homologation/racing and not street use. Most racers put 8" wide rims on the rear. Porsche wasn't producing/buying wheels like that from Fuchs, so they used what was around, which wouldn't fill out the wheel wells, especially without spacers.

some interesting points ...

I wonder if we will ever find out the one and only truth

With the production run of the 916 so small, my guess is there is NOT 1 simple truth.. but that each car had its own uniqueness.

Wheels: 15 x 7
Tires: Michelin XVR 185/70-15

PS: Note the seat cushion

Those look like standard 15x7 23mm offset fuchs to me. To fill the fenders you would still need spacers.

Yes. The factory ran 1" spacers on the 7" front wheels on the GTs, so it is very likely that's what they used on the 916s as well (front and rear) ...

The 7" R wheels are the ones to get for putting a 7 in the rear without flaired fenders.
