C6 Corvette ZR1 & Z06General info about GM’s Corvette Supercar, LS9 Corvette Technical Info, Performance Upgrades, Suspension Setup for Street or Track
Finally got around to installing the GS01 from Wheel Designers. Went with the deep concave and flush offsets. They were great to work with and super responsive to emails/questions.
@JABCAT the wheels look great. But can you comment on the weight difference and if you can feel a difference in the driving dynamics?
I didn't weigh them or the stocks before/after. The guy at the tire shop said he thought they were heavier, I thought they were lighter
Took the car out for about 10 mi of normal street driving after putting the new wheels on, so don't have any info for you their either unfortunately.
I went with this basically for appearance as 3 of my oem wheels were recently bent on my trip to the Corvette Museum, and I was unable to find any OEM Carbon wheels.
I actually prefer the look of the Cup wheels vs the original ZR1 style wheels when they aren't chrome such as the Carbon Edition or Z07 package colors of the wheels. Weights are very close though supposed to be lighter per factory promos on them. I think I weighed the fronts at close to 28 pounds and the rears at close to 30 pounds. Compare those stock weights to my C7 aftermarket ZR1 wheels, all 19 inches, that weigh 23.5 pounds on the front and 24.5 pounds at the rear. My 18 inch Forgelines on the other hand, are 20.5 in the front and 21.5 at the rear, roughly 4 times the price of the MMR ZR1 wheels. Racing strength and very light weight isn't inexpensive.
However, I would check the backs for where they were manufactured. I have several sets of C6 Cup wheels and they were all built in either Italy or Germany. The C7 Cup wheels I have seen were all built in Mexico and notorious for cracking on the inside rim whereas I have not heard of a cracking issue for the earlier C6 wheels made in Europe.
The black cups look great on IO. As much as my personal preference is chrome, I stick to Black with my two IO's. I use the black C7 ZR1 19 inch wheels on my Z07.

PS still haven't found the third Callaway CE owner.

These aren't GM cup wheels, they're from Wheel Designers and their forged GS01 style. I went with the deep concave and more aggressive offsets to bring them out flush with the fenders.
Re: the 3rd Callaway Carbon, Jim thought he had heard it had been wrecked, but I don't think anyone knows for sure. I've never seen another other anywhere.
@JABCAT I saw "carbon" on the wheel, and I assumed Carbon wheels...now I get it. They look nice.
FWIW; Regarding your OEM wheels and damage. I have used Jim at Weldcraft, Livonia MI for ~20 years. Between my friends and I, we have sent a dozen sets of track and street wheels to him over the years: Fix bends, weld cracks, and widen backspace or front space. Here is the picture of one mine, where Jim widened ~35mm which is exactly what I needed, and I added a 25mm spacer for a flush look and wider tire. (I have NO business relatioship, just a customer).

I have a couple extra sets of Carbon Edition decals I stocked up on so I put the wheel decals on the new wheels
@JABCAT the land missile looks fantastic! Love the orange with black. The vinyl is a cool touch also.
My local Discount Tire did a great job removing the tires from my OEM wheels & installing them on the new wheels. Was a bit pricey, but they did a nice job.
