Torque Obsessed

Tell that to Volkswagen and BMW. They figured out years ago that you can bring the fender lip down to the top of the tire if you leave enough room inside the wheelwell for the wheel to move. GM makes great cars but they seem unable to learn this.

Again, it is about the concept drawings. Not working on the street. Flush tires and no gap equals interference. I see it on the street with tires that show the evidence of interference. Heck, I did it as a teen, and had to “clearance” the fenders and get air shocks to keep from eating my tires after I discovered you can go too wide, no matter how “cool” it looked sitting still.

Wheel to fender interference is likely at play here, especially given the amount of compliance and travel Chevy builds into the C8 suspension vs a 911 or Cayman. There is a reason the Corvette has superior ride on the road (I did not say handling mind, you - they are pretty even there). Is it also possible that the thickness (not mass) of the C8's bolt-on SMC panels, plus a fender liner, is thicker than the equivalent unibody fenders and wheel-wells on the p-cars? That would also effect the ability to create room inside the wheel well the same way you claim the P-cars have.

Then there is this guy, widely regarded as one the the best automotive minds out there, about to release the successor to the legendary F1. Notice the wheel gap and inset? Maybe he knows something about design and setup that we don't, but Chevy does...

If you’re implying the gap is the same as the Corvette, it clearly isn’t. So maybe he knows something about design and set up that Chevy doesn’t.
