Haven't heard of it... kinda doubt it. Heck, a 96 B6 hugger won't fit your '03... and GSXR's have different swingarms, suspension, etc.
96-up GSXR what? 600? 750? 1100? Up to what? The GSXR's of the late 90's thru today have gone thru a lot of changes. I can't even imagine a hugger from a '96 fitting an '05.
