So I just found this nice set of original date stamped 1971/72 Pedrini wheels that I thought would look much better on my '74 2.0 than the Riviera's (stay tuned...will be for sale shortly). I plan on running the stock 165/80 15 tires as well.

The rears bolted up fine (of course, I had to go out and buy a set of 40mm length thread bolts as the Riviera's only used 25mm length). Then, when we went to mount the fronts, we realized that the front brake disc rotors had a hub centric ring and the back of the Pedrini's had a countersunk shape (see pics below).

Any suggestions how to make these work?

(BTW, the Rears fit just fine)

Thanks

Paul,

You can get a machine shop to mill out that inset at the top pic in all 4 or 5 of your Pedrini wheels.

Or else sell them off to a 70-72 914 owner on here ,& look for either the Pedrini or Mahle 4-lug ("Baby Gas-burner") silver painted cast 4-lug alloys, or the Fuchs 2L anodized forged 4-lug alloys - but they should all end with -01 in the part no. for the proper hub centric mill-out from the factory.

FYI - the Pedrini was still available in the early 73 MY, but I'm pretty sure not in 74 > - unless someone got the dealer to swap them from another 914 or had some carry-overs in stock (Gyp Iverson still had some as late as 75 when I was looking for my 914).

Also FYI - they all came with 5 - NOT 4 - matching alloys, but the dealers back then would steal the spare & replace it with a steelie, then sell 4 stolen spares at 100% profit!

PS - the factory alloy lugs were "acorn" or 1/2-rounded with a short shoulder & 38mm long with either a zilver zinc or cadmium plating finish, or some were offered later in the black oxide finish too. The acorn & shoulder are needed to seat, fit & hold properly, & many of the aftermarket chromed & other ones aren't the right fir. So be careful when looking. I think there may be some correct ones on here FS in the parts classifieds or check with Bruce Stone/bdstone on here, who's out in Riverside.

There's more on this stuff in "Wheels & Tires" the nailed topic over in the Originality & History Forum.

Al Reed up in Anaheim can do the wheel resto for you on the Fuchs, but maybe Cooper Boggs in Tustin could get a better silver match on the painted alloys, from our discussion on Sunday about my 85 325e's painted alloy resto (he says Al's PC metalflake is too big for perfectionists & CWs).

I'd suggest getting a COA from Porsche/PCNA to find out which wheels were originally on the 914 - unless you have the window sticker still & then it should tell you or the original owners.

If it's the green one, then it's well worth putting the correct original wheels on it - especially when you decide to sell it.

Drive it up to Krispy Kreme in Orange (The block/Outlets) - instead of or after your Tustin C&C at Enderele & join some other Teeners if you want to show/discuss it more.

I'll have my blue 88 Westy there, since my 914 resto is a long way off!

.... glad you joined us! .... & Thanx for supporting our White Gloves CdE!!

Cheers!

Also on a tangent ... put a post on here the week or so before your 2nd Sat gatherings, so those interested can come out!

Never mind. See one on top is the old wheel.

I know of three ways to make the .00 part number wheels work on a later car:

- Mill a recess in the back of the wheel for the centering ring on the late hub
- Mill off the centering ring from the late hub
- Change the struts and hubs (rotors) over to the early style with the pinch-bolt rather than the wedge pin ball joint

I'm not a fan of any of those, frankly. I suggest swapping the wheels out for ones that actually fit.

--DD

U can get the lug bolts from sources here and ebay. And. Real machine shop will cut the wheels for a perfect fit. Not a wheel shop from my experience. Cost me about $50 for all 4 wheels.

Thank you all for your suggestions. I'm not quite sure which direction to go. I will think about it a bit more before jumping.

Thank you again.

Cheers,

Paul

Get the wheels. You'll like 'em

Paul, meet Eric.

Eric has front rotors that I am pretty sure you can use!

I bought a pair of rotors from Eric and paid him to machine off the hubcentric rings (and press in the wheel bearings). Swapping them over took about an hour per wheel.
