Lightest 19" Wheel EVER???



19x10 et61 = 17.2 lbs = WOW!!!

Forged
I cant believe this wheel is not made in our offset or hole pattern.
This would be a WINNER for our cars.

Someone contact OZ Racing and get this wheel made for us already

its a centerlock wheel. i assume that if they make it for our cars with regular bolt pattern, it wont be quite as light.

not true
the 17.2 lbs spec is from the 5 hole version

Centerlock wheels do not add or shed weight -- they are just convenient for quick changes

One that you will certify meets either the JWL/VIA or TUV specs at the load rating of the E9X M3?

They also have a well known history and can be seen on F1 cars.

Not sure if many companies can compete at their level.

Great wheel from a great company but keep in mind that part of the reason that particular wheel is so light is the fitment:

19x10 et61

With this offset there is virtually no backpad which usually adds the most weight to the wheel. That same wheel in a 19x10 et20 would be significantly heavier.

OZ indicates their wheels meet both TUV and JWL/VIA specs (very good). The available Superforgiata's have an almost flat face and high offsets (9" is +53 MM and the 10" is +61 MM). Modifying the design to reach M3 required offsets would add weight. We also don't know what load rating the wheels are certified at. The wheels are made with 6061 aluminum according to the OZ website. My guess is that a 19x10 Superforgiata that works on the M3 (at the required load rating) would be in the 19 - 20 lb range like other high quality spread forged wheels.

Don't mind the people in the above picture... it was a PR shot.

And thank you wheeladdicts for bringing up a massive point on the backpad weight of the wheel in question!

Bingo...most people do not realize the amount of weight that a taller backpad will add. This is why most wheel companies advertise their "lightweight" wheels in a super high offset fitment

Cool. That's the first I've seen that ADV wheels meet either TUV or JWL/VIA standards. Are all your wheels now certified or just the 5.1's?

Now, back to the original question, can you produce a 17lb 19x10 wheel that will fit on an M3 that will meet JWL/VIA or TUV?

Thanks, you beat me with your post regarding the effect of offset. I went to the OZ site to get information about the wheel and see what they said about standards and testing. I didn't see that you'd posted until after I posted. I recall that at least some of OZ's forged wheels are made by Tanseiya (Neez, Dinan, Champion, RAC).

Advan got the RZ-DF down to the ~19lbs range on a 10" wide wheel. Here's a set that was just shipped out recently:


19x9" ET20


19x10" ET22

I dont know if this is true - about the wheel offset adding weight - but im going to take your word for it.
Now what about running a 25mm+ spacer to fit this or the OZ Challenge wheel.
A spacer weighs very little.... and i was very surprised to see the Rahal/Letterman running a 30mm+ spacer on their 2010 M3 GT2 challenger .... so that changed my mind about spacers and safety (if its good enough for pro race teams = its good enough for my silly street car)

You would need atleast a 30mm spacer to fit it on an M3 without it looking too funny (35-40mm would be ideal). Now a 12-15mm spacer weighs about 0.75lbs. If they even made a spacer that didnt require additional bolts when going 30+ mm you would be looking at 1.5lbs+ per wheel which puts it right at where a few other forged monoblock wheels are at. This isnt possible because 30mm spacer require extra bolts so you would be looking at about 3lbs minimum per wheel if using a 30mm spacer putting it in the 20lb range.

There is no way around it

Now yes the weight will be in the center of the wheel which isnt as "bad" as having it on the outer portion of the wheel but if comparing this wheels weight to others a lower offset would net a weight very close to the other forged wheels we already know.

Bottom line it is a great wheel but nothing "very new" in regards to low weight.

Now, back to the original question, can you produce a 17lb 19x10 wheel that will fit on an M3 that will meet JWL/VIA or TUV?
I spoke with our engineers at length about this and when i'm wrong i'll come right out and admit it. In an 18" application we can get there but on the M3 with the backpad it requires, and the fact that our wheels are concave and not flat faced (thus, they require more material) we can get in the upper 19's realistically in a 19". I think you'll find that to be the case with any 3-piece forged wheel, even the super lightweight versions from different manufactures should all come in around the low 20's but none of us can touch 17lbs in a 3-piece.

The reason our monoblock's can't compete with the weight again comes down to the concave profile we run on our wheels vs. the flat face of the BBS. Its simply a question of appearance vs. weight. The concave looks simply requires more material in the spoke designs.

I apologize again for the mislead!
