I got a set of BBS FI-Rs that are almost 10Lbs lighter per wheel than the Sport designs but being fully forged are supposed to be as strong if not stronger according to BBS. It may all in my head, but I believe I can feel a difference in how the car reacts to bumps and road imperfections.

 

Strong and stiff are not the same. Stiffness is what you could potentially feel. Strength is what keeps the wheels from bending or breaking in potholes.

 

I think he is simply saying the lighter wheel feels different. Less weight,....10lb/wheel,....would potentially react differently over rough surfaces.

 

Per Porsche, it looks like the center lock wheels that come stock in the GTS and Turbo S models are forged. The "plain" Turbo 5 lug wheels, which are optional in the Carrera models, are also forged. The sport classics are also forged.

"Wheels

The 20-inch 911 Turbo wheel

Forged, of course, to reduce weight and unsprung masses. With highly polished wheel centre.

The 20-inch 911 Turbo S wheel with central locking device

This partially black painted and highly polished aluminium wheel has been forged. It is especially light and sets standards in driving comfort and performance as well as in design. With central locking device including chrome-plated wheel centre with fullcolour Porsche Crest – and anti-theft protection.

The 20-inch Sport Classic wheel

As an option, you can select alloy wheels forged in a single piece with the fivespoke Sport Classic design. The spokes and centre have a GT Silver Metallic paint finish and the rim has been high-gloss polished. The wheel centre bears the Porsche Crest in full colour."

 

Today I fitted our new "from Porsche - Germany" Carrera Sport wheel set: 20" wheels with new P-Zeros and TPMS. I weighed the wheels using a very accurate suitcase weigh scale. Fronts 40.5 lbs each; rears 60 lbs each...this is of course the complete wheel/tire unit.

 

That front wheel sounds very light. Sure you didn't mean 50.5 pounds for the assembly?

 

Too late. The wheel sets are on the car and I don't plan to take them off to re-weigh them. But you are correct. Checking my hand notes I see that for the fronts it was 49.5 lbs per wheel. Much closer to your number. Thanks for the reality check.

 

I do believe tires has different weight variation; hopefully lets keep the wheel weight and tire weight separately. mixing it together to do a data collection may not be focused data.

just saying..

 

Those wheels look great on your car!
