18's come on a GT2 AWD?

Wish 22’s came with 22’s

Clown wheels. More-so when your brakes don't fit the wheels, which even with the brembos won't even come close. I wish the giant-wheel fad would go away. Just makes your car slower. Looks ridiculous. The 20s on my Camaro SS 1LE are too big. Car should come with 19s like the ZL1 1LE. Even a Porsche GT3 doesn't have 22" wheels, and it's brakes fit what it has on it.

So... what needs to be done to change that so the car will run a higher speed. Not that I need it, but I also don't NEED lowering springs or half a dozen other things for it but WANT them because they are available. Programming?

Yep, the ECU will have to be tuned to remove/raise the limiter.

I've said it before: AWD GT1 with 19" Michelin PS4 and I was still pulling c. 1 MPH per second when I backed off at 155 MPH.

I know that the rating for A/S 18" setups says "130", but I also know what I've read on here, with that setup topping out above 140 MPH. So, something is variable and doesn't add up.

The MY18's with the limiter originally shipped with a 140mph top speed limiter, but sometime during MY19, they lowered it to 130mph then had dealers start flashing ECU's to lower the top speed of the MY18's. That's why some 18's with the limiter can hit about 145 before it really kicks in.

my source being that my 18 AWD GT2 came with the original 140mph limiter and it killed all power at 144mph.
