Those are super nice, but damn they're expensive.
A lot of the rally guys I know either buy pairs of semi mudflaps at the local truck stop (for like $20 or so), or buy raw sheets of HPDE or similar, and then cut them down. Of course, the rally guys I know are probably tougher on mudflaps than the usual street car.
Be sure to post pics when you get em installed. I'm interested in seeing them on a Galant. My plan has always been to snag a couple pairs at a Mitsubishi Fuso dealer so I might be able to get a Mitsu logo on at least one of them.
