Early 911--901 (1971t) Boxster Rims?

[mikeyc71911t]

I have a beautiful 1971 911 t, 33 years in careful loving care, sold out of Beverly Hills Porsche. Now it's mine!! I live in Utah, one hour south of the mighty Miller Motor Sports Park. Oh yes, my 71, his name is Butzi (on his license plate too), he sees track time and is driven. I take excellent care of him too, I just also put him through all he's worth at the track. I am a PCA trained & registered instructor for their HPDE events.
Anyway, he is stock other than tie rods & anti sway bars by Tarret. I am limited now by tire width. He has his original Fuchs 15" deep dish shoes. I have seen and heard guys using Boxster rims, with proper spacing & longer studs. They are grip "Monsters" when done.
I am wondering if anyone reading this knows the magic combination, or recipe of Boxster sized rims, that will fit a 1971 911t?
Help me keep my Butzi in the fight against modern, non-German, rivals. "Porsche must win" (from Steeve McQueen, film, LeMans)

[Oh Haha]

With stock rear flares you won't be able to fit more than a 7 inch wheel. In the front a 7 inch SHOULD fit without rubbing, depending on your ride height.


No offense intended but I think Boxter wheels would completely ruin the classic look of the early 911. Obviously, it's your car and you should do what makes YOU happy not some clown on a car forum.

AS well, the spacers you will need to run to correct the late moel offset will add weight at the four corners which MAY cause some poor handling traits.

limited by tire width, and HP, torsion bars, stock bushings, shock valving, fender flares.......

With stock flares, I'd stick with fuchs.

I realize the look of Boxster rims, however they look ok and are strictly for track use. My problem is tire compound. I have run all sorts of tires, but finding 15" Hoosier slicks for my Fuchs is not on my list. Therefore, the 17" blacked out, Boxster rims. I realize the added weight and it's consequences.

(I forgot to mention I am a mechanical engineer, a 12 year Porsche tech & owned my own shop where I got to build race cars for everybody, but me. A car accident where a guy rear ended me finished my brilliant shop ownership and technician career. Back surgeries were involved.)

My car is not fast, and does not have a lot of horsepower, but it does have new Bilstein shocks and all the kibble, to make it handle well. My problem is I have to touch the brake pedal, "brake pedal bad". Even with good compounds, they are NO match for slicks. With slicks I can carry higher speeds through to corners. My experience with slicks is always one with envy, they make all my students cars that have them, do what they can't normally.

I have seen guys come out of state, during the national club event here, with the Boxster rims setup, on their 901. Unfortunately, I was not interested at the time to find the 901, Boxster rim clad, owners to find out exactly what sizes they were running. I too did not want to remove the Fuchs, any other rim does look worse on a 901. That was then, now I have changed my mind.

What I do remember is after my run group, one of them told me to put some Boxster rims on mine, to make it handle like theirs. He indicated to me that the small weight increase, even at the worst spots to gain weight, was still overcome with the tremendous grip from running a slick. It was that gentleman who I quote when I say "grip monster".

So, oh Haha, you think a 7" rim all around will fit? Do you happen to know what size spacers, or length of wheel studs I need? I have looked on the net for some time, but I cant find the right info yet. I do run all 4 rims and tires the same size now, which helped a bunch with pushing through the corners. It's also nice to be able to rotate the tires too.

We just had a HPDE with the Lapping Days Club a little bit ago, a friend emailed me that there was a professional photographer there. You can see my car at work, usually with a student in the car with me. If you go to Rennsportfoto.com, check the 8/22 day, bottom of the row, my car is the brown one. I like page 12, there are two pics, back to back laps, notice the white Mazda still behind after next lap. Of course we are not racing, but we do run them darn hard!
