[Chuck Cage] and friends have been building a variety of arcade racing platforms. The third version, pictured above, has a real racing seat and can support a 32″ television. They’ve got advice for navigating the local “you-pull-it” when buying seats. There are material and paint selection tips on the site as well along with pictures of their three different versions.
1. If you are interested in building a driving cockpit I would suggest making a visit to the build your own section of the Race Sim Central Forums. There is no more complete place on the web. They have everything from cockpit blueprints to, get this… custom Force Feedback shifters (using FF joysticks) not to mention some very involved custom motion platforms. There is truly no better place on the web for DIY driving game hardware.
