(IMG:style_emoticons/default/welcome.png) According to "A Restorer's Guide to Authenticity" a 914/6 M471 package had 15"x6" Fuchs with spacers.

Thanks. That sounds more like the wheel size for a standard 914/6. I thought they were more like 7's and 8's or 8's and 9's; thus, the need for the flares.

I always thought the reason you would often see Mini-Lites on the rear was that there were no Fuchs wide enough at the time? (IMG:style_emoticons/default/confused24.gif)

I am pretty sure M471's were 7's up front and 8's in back.

From what I understand, Fuchs were 8" and they used 9" minilites. But Porsche always had prototype and race parts for their race cars so race to race could be something else. And I think it was 6" on some of the rally cars.

M471 cars are also known as GT cars.

In pictures of the Daytona winning 914-6 the wheels do not look very wide.

Most people now put 7” up front and 8s in rear with factory flares. I have 8” and 9” 16 on my car now but have bought a set of 7” and 8” 15 to give what I think is a more correct look. But the correct 1970, 71 or so look of the wheels look whinny to me.

Pretty sure SVRA wants 15x8 as max and you can do that on all 4.

They look pretty good with 15x8&9 ...sometimes minlites on the rears.

I was just reading a quote from Steve Gaglione the owner of the Stenger GT and he wrote:

"My plan is to bring the "Strenger GT" back to its original form excluding a few very cool things that Erich Strenger did to the car. Like the 911S brakes and the 7 and 8 by 15 inch fuchs."

Perhaps there were variants and came with different wheels? Factory GT - M471 - M491

This is a great thread with Steve and Gustl adding info: http://www.914world.com/bbs2/lofiversion/i...php?t90377.html

According to the GT Parts booklet the available wheels were 6 or 7 inch as needed. There is a list of available spacers too.

I will try and figure out how to post the page here.

A well lit cell phone pic (from a modern smart phone) has sufficient resolution.

Which 914-6 GT cars are you talking about as your examples? There were only a couple of dozen made by the factory, the rest were done afterward by various shops, using some or all of the specific parts, often with the shop's own ideas thrown in.

Wheel sizes could vary from year to year for the same car--or even from race to race, depending on what wheels were available, what tires were available, possibly upon sponsor contracts, and more.

Your best bet is to either pick one car at one point in time and use it as your example, or just pick something that looks and feels right to you.

^ Dave is spot on.

"Correct" when it comes to 914-6 GT is a tricky subject. The factory cars ran rallies on 15x5.5 steel wheels and 15x5x5 Mahle alloys. They were also equipped with 15x6-inch Fuchs (and 15x7 Fuchs and maybe 15x8 Fuchs). But others built up 914-6 GTs from the kits offered by Porsche, sometimes using parts Porsche supplied—or some of those parts—and sometimes not. Those cars are considered real GTs, also—and may have run wider Fuchs and/or Minilites. 15x7, 15x8, and 15x9 wheels were all used in period.

I have a 71 date coded 9x15, maybr a pair, in my Fuchs stash. Peter Gregg ran 10x15 minorities as the widest fuchs were 9x15.

For a period correct look, I'd opt for 7&8 x 15"s. If you haven't put the flairs on yet, and have bank I'd go with 7 & 9 x 16"s but that's probably at least another $1500 over what you'd pay for the 15's

Hello. I am new to this group. I am looking for the original wheel and tire specs for factory 1970-72 914-6 GT's.


There is no one specific combination, they came with several options.

Basically, anything from 7"/8" to 9"/11" was possible.

Thanks for all the feedback. I was looking for factory GT specs which, from what I have read, appear to be 7 and 8x15's. Subject car already has steel GT flares, so those are the wheel sizes I will use if I go forward with the project. I used to race an IMSA style 914-6 GT in vintage so I am aware there were many wheel variants over time. That car had 11" rear flares with 10x15 BBS rear wheels. Thanks again for all the thoughts and information.
