Yeah? Z owners can't stand it when someone brings up the price issue compared to an 03/04 Cobra but I've read similar comments from Z owners about the new Ford GT. What's good for one should be good for another.
Sure you can buy a bottle for a Z. I've seen several LS1's popped at the track spraying. I'll stick with my 03. I had a Z rev on me in Hickory the other day and it sounded like a bunch of ball bearings in a steel five gallon bucket. I laughed my ass off especially since I am pulling about 200 more ponies than he's more than likely pulling. He made sure to rev on me when he was making a left hand turn and hit it just as he turned away from me. I know he was skeered. He didn't have to worry since I don't street race. I'd give my right nut to get that sucker on the track at Wilkesboro.
