1.03 torsion bars

For 150 bucks or so difference I don't see how the FFI's could be any better, as they both do the same job as well as the other.

Oh, that's right.
Some people like to spend more money on something than everyone else did.
That's what the FFI bars are for. :D

Unfortunately they are the only vendor that offers bigger bars beyond 1.03, and have higher spring rates for handling.
