That's what I recommended as well. He was looking to use them purely for the street, so a bolt-on spacer with its own lugs made more sense than new longer lugs that weren't necessary for his track wheels.

That's awesome about the bushings. STi should really have a Group N chassis and suspension bushing set with all of those in it. I'd have paid for that option.

I understand about the springs being heavier. I like them because there's a definite action to the shifter now instead of it amorphously going from 2nd to 3rd.
