Folks... did the 931 come with 4 bolt wheels?
I thought 5 bolt was standard on them?

Yep and Nope. 1979-1980 came standard with 4-lug. The 1980 931 "S" had the M471 package with 5-lug forged "gullideckel" wheels. Both years, the car could be optioned with M471, or with just 5-lug, and then you had your choice of ATS "basketweaves" or the "gullideckels". I'm not 100% positive, but I believe the 5-lug package became standard on the S2 cars beginning in 1981. I even saw a 1980 with 4-lug that had the LSD-equipped G31, strange though it my seem.

ah... so that means an early 931 (79-80) with 4 lugs would have come with 924 brakes rather than the 928 bakes up front?
So which steering wheel came on the early931s with the M471 package?

The US 1980 S package had the 930 3 spoke steering wheel.
Non S US 1980 931s had 924 NA brakes.

Nope had to be ordered separately.

I always wondered why North America had this odd thing happening at the time.
Some light on the subject over at GermanCarsForSaleBlog
| GermanCarsForSaleBlog wrote: | Porsche’s plan in 1980 was to keep the 924 Turbo’s price under twenty grand. Now if I were to tell you that in the face of a weakening dollar against a strong Deutsch Mark that USD $20,000 has the same buying power today as USD $57,115, you’d not only have to pick your jaw up off the floor, you’d wonder why the hell Stuttgart decided it a savvy move to wipe the 5-stud hubs and rear disc brakes clean off the build sheet replacing them with four lugs and a pair of drums for Turbos destined to the US to stay under that price. Let me explain.
Porsche was still a small company 35 years ago compared to, say, their neighbors at Daimler–Benz. And when you’re a David, you do what have to in order to keep that needle millimeters away from the red lest A: you get consumed by Goliath, or B: you close up shop. Simple as that. So in order for Stuttgart to continue selling its relatively new entry level product at a far from entry level price in a market that was allotted 50% of its Fahrzeug (incoming CEO Peter Schutz would change that in 1981 to lessen dependence on the US market), costs had to be cut somewhere. Unfortunately, the rear binders were it. The way they saw it, if the 50 states version was detuned to put out 143bhp @5500 RPM and 147 lb-ft of torque at 3000 RPM further crippled by a smaller turbo, catalytic converter, and oxygen sensors, a front disc/rear drum set-up like that found on the normally aspirated 924 would be more than adequate.
The 924 Turbo made its appearance on our shores in July of 1979 as a 1980 model (easily distinguished by an exposed fuel filler cap) in a limited batch of 600 cars in an effort to keep dealers and journalists from screaming like spoiled little brats since Porsche had already started production of the 1979 model year in the summer of ’78. When you figure in that the European/ROW version got 170bhp, 180 lb-ft of torque, a larger KKK K26 turbocharger with a wastegate, and disc brakes all around, who can blame anyone for throwing a tantrum? Matter of course. |
Couldn't find much info on 924.org about this subject but it does sound legit…
Regards, Harm.
