Hey: I am new to this forum and drag racing and frankly Camaro owning, but I have a 2012 Convertible and just did my first modification. I can see a rollbar in my near future. Do you still use the roll bar on your car? how much does it weigh? What times are you pulling on the 1/4 track? I take mine out again on Wed. night and I am in Colorado (Up High). I have only pulled a 14.6 as my fastest w/out modifications. Any info you have will be helpful as I am the only one out there with a stick and a convertible.
