What causes a forged aluminum wheel to weigh so much more than a comparable OEM wheel?
Love the look and finish off these wheels, but i'm not going to add 30+ pounds of rotational mass to try to save a few grand on a $150k+ sports car.
Generally speaking (for general automobiles and not porsche gt3's) cars have cast aluminum wheels from factory which are cheap to make but heavy. Often times people will buy aftermarket forged wheels for weight savings and performance improvements over cast wheels. So generally, people see a weight decrease when switching from an oem wheel to an aftermarket forged wheel.
However, premium cars like Porsche gt3's will have forged wheels from factory. Thus when someone changes the wheel to an aftermarket forged wheel, and especially if they're going from a monoblock to a 2/3 piece design there can and will be an increase in weight. Usually people have these reasonable and realistic expectations and they're willing to sacrifice a small increase in weight for a customized look and etc.
My suggestion for the $0 amount it's worth is to not incorrectly assume you'd see a 30lb weight increase with a given set of wheels. Find out from a reputable source or your own measures what your wheels weigh, than get a proper quote from the company you're shopping with and from there make your determination. I'd take the numbers that some people have thrown around here with a grain of salt and come to your own conclusions.

Hi there,
Thank you for your message!
Regarding wheel weight, it largely depends on the design. The previous OP was comparing his set to his HREs, which are four times the price. While they do weigh less, at what point does a $10,000 difference justify a few pounds per wheel?
As previously discussed, the OP did not mention wheel weights or express any concerns about weights in general. Moving forward, it is crucial to have this conversation to prevent similar issues in the future. We can certainly produce wheels that are close to OEM weights while exceeding their fit and finish.
I personally own a GT4 that I track, so I understand the effects of unsprung weight and rotational mass. I acknowledge the oversight regarding the weights of the 992 GT3 set, and as a business, we have made it a priority to discuss weights and expectations based upon design, before entering the rendering phase to avoid any discrepancies.
Thank you, and please don’t hesitate to reach out with any questions.

What makes two aftermarket wheels with similar designs differ in weight when they’re both forged aluminum?

It primarily comes to down to design and load ratings. Design in the sense of shedding weight via slimming spokes etc. and load ratings to the extent of the load rating figure itself. We use load ratings that are 1.5x of stock to ensure utmost strength and durability.
However we can deviate from that if weight is the primary concern, and match the OE load ratings. I hope that answers the question, feel free to PM us any other questions! Cheers.

That is good to know. So, if I wanted an OEM load ratings for a design similar to BBS, HRE, or Apex wheels, you can come close to the same weight? +/- 2lbs?

Give or take a few pounds, yes, assuming the design allows!
A stunning set of 997.2 GT3 wheels. This set is modeled after the OEM .2 GT3 centerlock wheels, but feature a modified 5-lug configuration. This set includes modified offsets to allow for a flush fit without the use of spacers. OEM+ 🏁
