Another option is the Corbeau Classic (
Corbeau: Classic Bucket). While I like the seat, I don't want vinyl seating surfaces. When I spoke to the folks at Corbeau they said they'd build me a pair with fabric seat and vinyl bolsters and trim (like their Classic II) for the same price. The only downside is the seats would take 10-12 weeks to be built, but it's still a good option.
BTW, the Corbeau Classic is available in black leather in the U.K. (
Corbeau Classic Seat - Leather - Ears Motorsport) with black or white piping. I have not asked Corbeau U.S.A. whether they're also available in leather in North America.
BTW, their seat adjusters are in front, not side mounted, so no problem in a Cobra.
