That and aero. Corvette has a much smaller profile to the wind and one of the lowest CD in a production car that helps when you start pushing over 60 mph on your way to 100.

New OEM tires are not. But putting more expensive or purposeful tires on is a mod. Take a Camaro 1LE and put the Z/28 Trofeo' tires on it. Performs better? Then it's a modification to the original OEM spec.

Tire pressure would likely be a track specific alteration, but in the strictest sense.............a modification.

Emphasis on BRICK



I always enjoy the "if I put $10,000 into my XYZ mobile I could take a ABC mobile for half the price" discussions. As long as you give the other driver the same $10,000 to put into the other car, maybe a fair discussion.

But OEM to OEM is the comparison of two or more companies engineering and customer knowledge. The OEM has to meet all Federal Standards for emissions, and must comply with CAFE standards and meet the OEMs internal durability requirements. What you do in the aftermarket does not. So for me, an engineer in the industry for my entire career, it doesn't matter what you can do in the aftermarket. But that's JMO. I understand why it matters to others.
