To the C6 owners out there who were C5 owners.

Did GM fix the tire roar that comes from the rear and drowns out all else on the C5?

not totally

Between the Borla Stingers on the C5 and the Flowmaster American Thunder Kit on the C6 I didn't even know the tires were noisy

If it bothers you that much click here to see how to make it better.

I plan to get rid of my C5 which I bought new in August 87 (98 model) this spring/summer and I'm contemplating my next vehicle, as my "dream house" is now about complete, and I can think of other things. I really would like something that is able to function as a long distance cruiser, as well as a "drive it like you stole it" car.

The C5 plain gets tiring on long highway runs due to the endless tire roar. So, mostly we take my wife's turbo Subaru. It's much, much quieter - very little road noise, but it is a bit spoiled by lack of a tall highway gear - although because of that gearing, 70-100 is but a tip of the throttle away, as the turbo is nicely on the boil at that point. And above those kinds of speeds you just go to jail if they catch you. The C5 has a great highway advantage though - road presence. You come up behind people and mostly they move over, whereas they pretty much ignore the Subie. Until it blasts past them.

I'll have to try a C6, but the tire noise factor will be big in the decision of whether to buy or not.

the tire noise on the C-5 is caused by the tread design of the goodyears.the tires on the C-6 is much quieter BUT to prevent the front tire from wearing on the inside edges and causing them to get noisy set the camber close to "0" as possible.

The original Goodyears were really noisy new, and worse as they wore. The replacement Firestones were better new, but have now achieved the same noise level - very different tread pattern. But they have lasted a lot longer. All the noise I get (in a coupe) comes from the rear tires; I guess I was just hoping GM would have done something about it for the new model.
