Recent testing at our Milford Proving Grounds has taught us that we need more rear downforce on all three 2015 Z06 models (paraphrase of Tadge Juechter at NCM Bash). Here are the first examples. Tadge noted that they have learned, now that the record winter snow had recently melted and that could now start to use Milford, that previous plans to use the StingRay's Z-51 deck spoiler on a stage 1 had changed, noting that more rear downforce was needed on the stage 1 model. Here is the first real world testing consequences, as perhaps the previously envisioned stage 2/3 spoiler is being field tested on a stage 1. Note, the heretofore strange combination of a phase 1 front splitter and a stage 2/3 deck spoiler. Also changed is the first time use of the "curved aero blade" on the rear fender transmission cooler intake grill on a stage 1.


A second car, also testing at the Tail of the Dragon, shows us, also for the first time, some new wheels. Are these going to be Z07 unique, just as there were "lightweight wheels" for the ZR1 in later years? Or might these be available across all Z06 stages? (I hope!)


And even the aero blade is changing slightly -- not the pointed edge-transition in its middle instead of the curved one as on previous show cars.


Finally, also consistent to what Tadge stated at the Bash, please notice that the center section of the spoiler, heretofore approximately the same height as the outside wickerbill, is now a little taller -- again consistent with the need for more rear downforce.




Thanks to Manuel Carrillo III for the pictures!

Need to backtrack on the fender aero blade changing. Thanks to "rdslon01" pointing out an earlier thread with great pictures, found a different angle on the aero blade, and it does not look as if it has changed at all.

Sorry for me don't care much for the bigger spoiler they should make it an option for the stage 1 and stay with the Z51 spoiler, much cleaner and since I'm not racing it don't care or need the stronger down force.

Thanks "lsxjunkie" for noting that they are C6 Z06 & ZR1 wheels! We sure, however, have not seen them before on a C7 Z06. I sure hope that those C6 cup wheels are offered as an option across all C7 Z06 three stages. With some saying that cup wheels are at least a three pounds per wheel weight less, and many saying they are five pounds per wheel lighter, there is no better handling bang for the buck than reducing unsprung weight, e.g. lighter wheels. And they would be so much easier to keep clean than the "twin Y" Z06 wheels. Much as I love the love of the Spectra Gray with machined groove wheels, hope we see cup wheels as an option in September when the Z06 "dealer order book" is estimated to become public.

For 2015, we have two Corvette "families," e.g., StingRays and Z06's. A 2015 StingRay will not be a Z06, nor will a Z06 be a StingRay.
