I attended a track day on May 6th 2012 at Auto Club Speedway with my good friends at HG Motorsports. This was just a track day and by no means, a competitive event. I had run a few sessions on the course and I decided have a go with an instructor in my passenger seat. When I came in to turn 16 of the “Sports Car” layout, instead of turning, the car proceeded to skid to the ground and I went straight off of the course. I looked in my rearview mirror and saw my wheel rolling out behind me. I knew that all of my wheels had been torqued properly, as the instructor did it himself. From the way that the car had ended up, I immediately had a feeling that the front passenger side wheel had broken. Sure enough, as you can see from the pictures, that was the case. Keep in my mind that I was also riding on a brand new set of Michelin Pilot Super Sport tires. Because the wheel had come off, the car rode the 14.25” inch disc of the AP Racing 6 piston front brake kit. In addition, the wheel and tire had bounced around in the front fender, inside the wheel well, causing severe body damage.

HG Motorsports was kind enough to put the car on their trailer that they brought their race car on and tow it back to San Diego, while they drove their race all the way back to San Diego. The car was brought to Heinz Geitz Autohaus, a sister company of HG Motorsports, where they were nice it enough to leave it on one of their lifts until we could get some new wheels on the car.

About the wheels: My father had purchased these wheels brand new from Peter at ACG back in March of 2011-- Cor Precise in 20”x9.5 in the front and 20”x10.5” in the rear with a brushed center and polished lips. A week before the event at Auto Club Speedway, I had the center of the wheels painted gold. They were not powder coated, nor were they disassembled. They were professionally prepared and painted by a well known shop that does wheel repair work and prepares race cars.

After the accident, photographs and word got around quickly. The very next day, Peter from ACG called to let me know that he had heard what had happened and that he had already been in contact with Cor. Cor wanted us to send the wheels back to them for testing to find out what could have cause the problem. After “analysis,” Cor denied the responsibility and determined that the wheels would not be covered under warranty.

Our attorney sent a letter to Cor asking them to reimburse us for the wheels and pay for the damages to the car. Their reasoning for denying responsibility (see email) was that because the wheels had been painted and because I was at a track event, they were not under warranty and therefore Cor would not pay for the damages. Conveniently, Cor actually added the “track use” specification to their list of what denies warranty after we had brought this issue to their attention. Luckily, two days after the incident happened, I actually took a screenshot of their warranty page before the change. As you can see, the original page did not include the specification of “track use.”

Cor states that they are denying warranty because the wheels were used on the “track” when they have conflicting information on their website that promotes the use of their wheels on “tracks”, in “race” type functions, etc. I have posted photos of various instances where Cor uses these phrases throughout their website. I apologize in advance if some screenshots may be difficult to read.

For those of you who have a set of Cor wheels on your car, I suggest you have inspect them immediately. For those of you contemplating about purchasing a set of Cor wheels, I suggest you look elsewhere for a set of wheels.

This is the email the owner of Cor sent to our Attorney.

Mr. M****s,

We have received the wheels returned for warranty consideration. I have personally inspected the wheels and they conform to their design specification. The wheels were in fact repainted as your letter states and I am concerned about possible effects of the 3rd party paint process may have had on the wheels. Some processes have been known to adversely affect the aluminum material, which could lead to a failure of this kind. As mentioned, I will be having a sample of the failed wheel tested. In the meantime, I have had a chance to familiarize myself with the details surrounding this incident and I would like to point out that our products are designed for street use. The loads and the duration of the loads presented in a track environment are far greater than those experienced in day to day driving. I am sympathetic to your client’s unfortunate experience but I feel it is unreasonable to expect our company to be held solely responsible for the damages when the product was clearly not being used in the manner for which it was intended. As your letter states and the photographs provided clearly indicate, the vehicle was at a race track and the client was at an “instructional driving event”, not simply a car show. On this basis, we would have to deny the claim for warranty consideration.

If you would like to further discuss this matter, I would be more than happy to make myself available for a telephone conversation next week.

Kind regards,
Robert Herrera

Here is a topic on Cor's blog in which they use a photo of our car, which they call a "Camaro," that Cor states that one can "gain unmatched performance on and off the racetrack" with their wheels:

Wow this is terrible. I have never seen a wheel do that. And the fact that Cor denies responsibility is outrageous. If a paint job ruins the forged aluminum wheel strength, something is wrong with their wheels and maybe their production or casting process.

I can't believe they would say their wheels are intended for street only use and not race/track use. That's just plain BS. You are a wheel manufacturer who markets to the aftermarket tuning community and they say it's not for track use?!? Who are they kidding.

Buy authentic. Go HRE's. :)

Such a wheel would never survive the "Tüv" test procedure here in Germany....even while looking at it it is clear to me that its made for looks.....not for track.

Beautiful wheels,but made for the guys who cruise around in daily traffic.....i would not take anything like that on a track esspecialy on a heavy and very hard cornering car like a GTR.

Wow..... you would think that cost of replacing the wheels and damages to the car would be much less than fall out from the bad PR and attorneys fees. Something like this would make me never purchase a product from their company....they should be ashamed trying to blame paint....

Apparently you cannot use these wheels on the track, since they changed their warranty after the incident and even though they brag about multiple times on their website. It voids the warranty if you do.

Wow this is terrible. I have never seen a wheel do that. And the fact that Cor denies responsibility is outrageous. If a paint job ruins the forged aluminum wheel strength, something is wrong with their wheels and maybe their production or casting process.

I agree.

First time ever seeing something like this happen. I hope things work out for you. And did I hear that these wheels are forged? seriously?


Yes. They are supposed to be fully forged.

Wow..... you would think that cost of replacing the wheels and damages to the car would be much less than fall out from the bad PR and attorneys fees. Something like this would make me never purchase a product from their company....they should be ashamed trying to blame paint....


These are the exact thoughts we have had.

amazing how a company can be so short sighted.... and to change their warranty text online afterwards? this pictures alone will cost them way more than it would have cost to just pay for the wheels and damages to the car... not to mention they are lucky that no one was hurt, a good PI attorney would have destroyed them....

is this just limited to cor? I thought there were a few brands that shared the same manufacturing plant/process?

WOW. Looks very much like the accident I had on an autoX course a couple months back, but that was with the OEM wheel falling off due to the OEM studs breaking under stress. Bad luck for the passenger front wheel :sad: Unbelievable that a wheel like this would break so badly, and that COR tried to deny all warranty/responsibility.

Just another reason I personally stick with Volk/Advan/Etc for track wheels

True. The same company that build Cor wheels also builds wheels for other known brands. Some of which are often advertised on this site.

The Facts:
The wheel failed at a track event not a racing/competitive event.

Per Robert Herrara (in above letter) at COR the damages were denied because they were incurred as a result of track usage.

The damages were NOT denied by COR as a result of painting as evidenced in above letter.

COR clearly says (in above letter) that their wheels are designed for street use. (They won't tolerate track use?)

The web screen shot of 05/08/12 above clearly states that COR wheels will void warranty if used for competitive purposes but does NOT mention HPDE's.

The web screen shot of 07/11/12 has different language from the screen shot of 05/08/12 that includes unusual prohibitions for "Track Use".

A quality aftermarket wheel would customarily be built to factory quality standards at minimum.

A quality aftermarket wheel that is purpose manufactured for a high performance vehicle would customarily by design and construction be able to serve its design intended purpose without failure.

The vehicle manufacturer considers HPDE's within design intended purpose so aftermarket wheel manufacturers must abide by the same. (I have been to many vehicle manufacturer HPDE's held at road racing circuits to drive their new models)
