Sticking the .car file I'm using for the C7 here in case anyone has any suggestions. The power is way over the 170bhp it should have and the tires are fairly close to slicks but C7's have had every kind of power unit stuck in them, there were even a few 4x4 ones made. One here in Ireland had the running gear from a 320bhp sierra cosworth 4x4
. I'll be staying as close to standard as I can for the default cars.
