If and when you manufacture them, I am will be on the buy list. I have been searching for anything that keeps the factory MR, while getting above ~250-275 spring rate up front. Looking forward to more info.
FYI the steeda gt500 dual rate springs are up to 350# in the front, and are interchangeable with the BMRs. I got the same ride height out of both. The rear is a bit stiff at 1200.
