We recently scored a pair of Corbeau suspension seats off Craigslist. They even came with mounting brackets.
At first I was a bit concerned that the seats may be too firm for my liking. After the first drive I knew we made the right decision. Just driving around town they soak up the bumps like no tomorrow. I don't think I'm ever going back to factory seats again! The next thing we need is a cage and some harnesses.
