Curious to find out more about oz wheels being used on the track. I know that oz's are a little cheaper than hre's and bbs wheels but I've seen a lot people using them here and want to know if they track them.

 

I too have been curious about this... Love to hear everyone's thoughts

 

You should be fine with one of their forged wheels. Personally, I wouldn't consider a cast wheel for track events. Best,

 

I pitted next to a .2 GT3 a few weeks ago and the cast $2600 OZ wheels with Hoosier R6 were mounted on it. I talked to the owner for a while for 2 days and he has not had any issues with the cast wheels. Also DeputyDog on these forums ran a cast OZ wheel on his supercharged 996 for a while and some spins and offs with zero issues. I see guys racing in PCA and PBOC on cast wheels all the time with no issues.

So this is why for me I am having a hard time deciding to either buy the cast OZ wheels or forged OZ or something from Forgedline for $2-3,000 more. I'm trying to justify the extra expense myself.

 

Porsche uses cast aluminum that are made in Italy for the 997.1 gt3 oem wheels and I think oz wheels are also the same, but thanks for ur opinion on cast aluminum.

 

I wouldnt be worried about their durability. I have them and they have held up fine on these rough northeast roads. Many cars running around Germany and the Nurburgring with them as well

 

The HLT cast OZ wheels are VERY strong. I have 2 sets of 19in Ultraleggeras. No issues at all and I double duty the car with the wife.

 

I believe all OZ wheels are also TUV approved, although each wheel has its own load rating for their specific applications.

 

Why?

There's lots of discussion on this on both Allegerita and Ultraleggera threads. If cast correctly (pressure cast, heat treated, shot peened) a good cast wheel is nearly as strong as a forged wheel is. A forged wheel's primary advantage at that point is that the spokes can be designed a bit skinnier and still have the load rating so the wheel can be made a few pounds lighter. A great example is OZ themselves. A 19" Superforgiata is 2-3 lbs. per wheel lighter than an Ultraleggera is, but twice the price. BOTH are tested and pass to the same German TUV standards for strength.

I have sold dozens of sets of Allegeritas an Ultraleggeras to you guys at this point for track use. I can say emphatically that they have proven excellent for their track worthiness. Remember, any wheel can bend or break if hit hard enough. So if it happens it may as well be to a wheel that you don't have a problem with just throwing out and replacing.

I welcome anyone to call me to discuss further.

 

Damon,
You know a lot more about wheels than I do so it's good that you weighed in on this topic. My reluctance stems mostly from anecdotal stories passed on by other track guys who had or knew of a bad experience with a cast product. No telling how much hyperbole was involved, what the particular circumstances were or even who was the manufacturer was so perhaps it's unfair of me to characterize all of them in such a harsh light. I'll try to keep a more open mind. Best,

 

Just like Damon stated, cast can be strong, but must be combined with an engineered design, the result is a strong cast wheel. BBS, OZ, Rays have very well engineered designs.

Forged wheels have the potentially to be lighter, however require the proper engineering to each vehicles load rating. The combination of the forged aluminum and the engineering are what make a great wheel.

 

Grass Roots magazine just tested a cast vs forged wheel. The Forged was lighter but on the track it did not prove to be any faster.

 

I have used them with r6's for about a year and they have been great. Pretty sure mine are the superlagerra's. Whatever the 19" version is.

Buddy of mine with a rs has been running them for at least a couple years.

Still love the other options for track wheels. But, for the price and knowing if I mess one up I can throw it away, you can't beat the OZ wheels.

 

I have had 18x9 Ultraleggera's on all four corners on M coupe as track wheels for about three years with 10 to 12 DE's per year, zero issue's.

Now I have a set of 19" Ultraleggera's on my C4S and have used them as my street and track wheels for the last two years, zero issue's. They are pretty light and in my opinion extremely strong as I drive across these really bad railroad tracks everyday (twice) and they are still straight and true.

If I do manage to bend one to the point where it can not be straightened I also know that it won't empty my wallet to replace one. This is my fourth set of OZ wheels and I have zero issue in recommending them to anyone for track or street wheels.

I should add that I think the black wheels look great on a white Porsche but I might be opinionated in that regards.
