I thought they only offer standard and low profile, also one for 3” inboard spring relocate. Low profile only means that there is extra ground clearance between the bars and the ground which is more suited to street use. Standard which will run more parallel to the spring are close to the ground and would be more suited to all drag or track use. I’ve heard standard perform better in terms of better traction.
Because you have 3" inboard spring relocate I think you only have one choice of bar, the standard one designed for inboard mounting.
I’ve heard all of them are noisy
