My name is Steve Schardt. I am the Founder and Sales manager for Forgeline Motorsports. My User Name includes the word "Resource" and that is what I would like to be, a resource. I have attached an article that was published June of last year in the Sports Car Magazine. A publication directed solely to sports car racers. The technical pieces were from Forgeline. Some of it is more technical for me... However, it explains why Forgeline uses SAE standards to calculate loads. It explains why FEA ( Finite Element Analysis) is an incredible tool for engineering race wheels and why load ratings are critical to selecting a correct wheel for your corvette. I hope you find it interesting. Please let me know if you have any questions... If I do not know the answer I have a few engineers down the hall I can ask,,,,Yep Right here is the USA!!
First off thanks for making a great wheel in the USA- mine are slated to be finished any day now
Second thanks for stepping up to be a resource of information
When one looks at fatigue I see a figure thrown around that 4 years of racing should be considered a life span for wheels, conversely the same set of wheels would last decades on the street. I'm curious as to what force and where on the wheel creates the killer stress on a track wheel vs a street wheel.

That's an interesting point, considering that race wheels will see loads generated by cornering, that are far above what a street wheel will ever see, but the race wheel will never see stresses from potholes and expansion strips, that a street wheel sees regularly.
Actually it sees far greater impacts on the track. Our wheels hit apex burms at more than 150 miles an hour. Racing wheel are subjected to going off track and hitting holes at much greater speeds that are generated at a street level

Mr. Schardt, with all due respect, I understand what you're saying, and I'm not trying to stat an argument. However, what part of the country do you live in? I'm in the north east "snow belt", and after a hard winter, before the weather warms enough for the road crews to make repairs, we routinely will see "potholes" that are 3-4' long, and 5-6" deep, and not just on city streets, where you can hit them at only 35 MPH. I have yet to see a track with that kind of "obstacles".....

Does the Forgeline three year warranty cover issues as a result of the above?
[QUOTE=Kamran;1595539892]Above, you said:
"Our wheels hit apex burms at more than 150 miles an hour."
So we should stay off rumble strips, to maintain warranty?[/QUOTE
Most DE track participants are not hitting the berns at 150. These races cars are set up for it. Street cars do not do as well. If you you purchase a set of Forgeline's and bend one on a berm I will personally fix it. I would be more worried about your Corvette
As a user of the Forgeline Product, I am happy to attest to the quality and durability of their product as A+
I have hit many rumble strips and berms with my old beater and never so much as warped a hoop... Keep up the great work Forgeline !

Why your wheel just broke
