Yes, its only included with the Cold Weather Package.
I still dont know why you are so worried about T/C. It really isnt that big of a deal. Just because you see people complaining about it, doesnt make it worse. You may lose a 1/25th of second with traction control lol. I've never understood why people wasted time bickering about such a miniscule thing.
Anyhow, as far as using smaller diameter wheels to drag race, your only going to go as low as 16 inch wheels on the SVTf, because of the 12" brakes. (11.8" for those that like to be technical).
If you are looking to buy a "drag racer" Fast & The Furious street/strip terror, I suggest you find another option. Because this car is not built for the straight line. Sure, you could mod it out effectively and race up and down the street all day, but your going to spend a pretty penny.
Dont buy an SVTf if you want a "straight-liner".
