Has anyone fitted S2000 seats to a Sportster? The frame on one of my Cobra Roadster 7's is cracked so I'm thinking about changing for something more substantial. I don't need the harness holes anymore either as I've switched to 3 points reels. The seatbelt guides on the S2000 seats would work quite nicely.

I have seen MX5 seats fitted and I heard Porsche 997 seats fit, are there any others worth looking into?
