I'm looking to upgrade my 06 GT Convertible and noticed that BMR is one of a few companies that offer packages for ragtops. Does anyone have this package? If so, what are your opinions of it?

Are there specific spring rates for convertibles? Can I just use coupe springs?

I know I'm asking a lot of questions, but I wanna be sure I'm buying the right products before I go dumping 1,300-1,500 on a kit.

Thanks!
