I was just wondering if anyone had the weight specs of porsche factory rim's. Fuchs, D90's, Phone Dials etc..

Weights:

I ued a fairly accurate bathroom scale for the following weights.
They may be off but they wre all double checked and off the same scale.
Here's a sampling of wheel weights, in lbs:

7x16" 951 phone dial pcast 18.5#
8x16" 951 phone dial pcast 20#

7x16" "dish" Forged 18,5#
8x16" "dish" forged 20#

7x16" 951S FORGED 18.5
8x16" 928 CS FORGED 19
9x16" 951S/928CS FORGED 20

6x16" 911 fuchs 17
7x16" 911/951 fuchs 18
8x16" 911/951 fuchs 19
9x16" 911 fuchs 20

7.5x18" HRE 504 cast ctr 3-piece 16.5
9.5x17" " " 18
11x17" 19.5

7.5x17 Factory 993 pcast 18
9x17" Factory 993 pcast 19.5

7.5x17" Mille Miglia C2t style (late) 24
9x17" " " " 26

7.5x17" Mille Miglia C2T style EARLY 25
9x17" Mille Miglia " " 28

7.5x17" Borbet C2t style (EARLY) 28
9x17" Borbet C2t style (EARLY) 30

7x9" FACTORY C2T pcast 22
9x17" Factory C2T pcast 23.5
Interestingly:

951 Aluminum spare -w- tire 26
911/944 steel spare -w- tire 34

The aftermarket wheels weigh 6-10 lbs more than similar factory wheels.
That is ALOT!

I was also surprized at how light the HRE wheels are even with cast centers.
Phone dials are also much lighter than I expected.

 

Phone dials also bend pretty damn easy I hear.

 

You know, that seems to be the rumor, but PD's are actually pretty strong. I have autoXed mine and no problems so far, alot of people will tell you the same thing.

..Why would autox cause a wheel to bend?

 

Aren't PDs Mg alloy?

 

not most but 951 club sports came with magnesium alloy wheels IIRC. They also had sweet fiberglass hoods from the factory, and magnesium intake manifolds.

the club sport's were the wheels on MY87-89 951's,
"cup" were the turbo cup cars
