I just had mine installed. Worth every penny. No sloppiness at all. Those who are scared about accidentally putting it into reverse.....it takes a lot to get it into reverse lol. I doubt anyone would be able to do it on accident.
I have the hatless LT with a mach V. Honestly it's much more manageable. Its quiet unless I step on it. A little louder than stock if I shift around 2500 rpm.....above that it sounds pretty mean and no rasp at all. I had the solo race and lt before and it was horrible.
Same thing happened to mine, super small bubble though. Luckily I had brought warranty at america's/discount tire right when I got the car and got a new tire under warranty. If you have the tire shop call pirelli warranty line they sometime can give you a proration. But might be out of luck...
