Traction system active
I recently bought wcc946 wheels and tires from west coast corvette. I have 19in in the front and 20 in in the back. Now when I am going between 65-70mph the traction system active display comes on. I can't accerate and have to turn the traction control off. Any ideas?
Never had problem until I changed from the stock wheels and tires.

What size (diameter) tires do you have? If the rear diameter has dropped to close to the front diameter or the front has increased to close to the rear you will get this problem. You may have to change one set of tires to a different diameter. A lot of C5 people ran into this problem.

As per the Tire Rack, stock C6 diameters are 25.7-F and 26.9-R.
You don't have to match these exactly but you need to maintain a similar ratio of front-to-rear diameters.
Different diameters affect your Speedo readings as well, but you probably already knew that.
