New 2014 CTS-V Coupe Owner

Need Fatter Tires.



The car is actually fine in the snow. But not with its summer rubber, and especially not with extra wide summer rubber. Get some Goodyear Eagle M+S tires and the car will go through snow no problem. Do not, however, disengage TC and AH since you're still going to try and sling the car around even though it's snowy (maybe more because it's snowy, I know I do) and there's no getting around the car's inertia and high HP.

I owned Corvettes for about 22 years. I live at the top of a steep 800ft east-facing hill in Massachusetts. We get a lot of snow. With M+S tires on a C5 Corvette, I would have to go around FWD and 4WD cars with "4 season" tires who were stuck. I'd always give 'em a little "toot toot" on the horn to help them realize they bought the wrong kind of car for winter driving. But really, it's all about the tires. With good tires, every car gets around in the snow OK.

FYI:
1. when the factory warrants the supercharger noise, it is their practice to replace the entire supercharger because it's quicker and easier than just directly repairing the noise. When the noise isn't covered under their warranty, the standard fix for most folks is to address the noise, itself at a cost of <100 bux for the part (solid isolator) and a couple of hours of relatively easy work. It's not really a $3000 repair unless GM's paying.
2. change BOTH upper control arms. They are a common source of suspension noise and its a good idea to do both UNLESS you are paying dealer rates to do it. Also a surprisingly simple task.
3. if D-I-Y is not your thing (no shame in that) find an indy shop with a good rep as the dealers are too expensive AND too restrictive on what they'll install.
