Pretty much anything that says X2C motorsports(before they divided into modular powerhouse or whatever it is now) or CFT(central florida
turbo) sticker on the windshield, you can bet 99 times out of 100 it's going to be fast. I've heard they stickers alone will make you run 12's.
I remember when X2C did an 03 Cobra, I swear when it launched you could see ever inch of the undercarriage. I believe the car went 9's.
