Patrick Dempsey: I Got Screwed in a Race Car Deal

Patrick Dempsey is racing to the courthouse with a lawsuit against a sports clothing company he says stiffed him.

Dempsey claims in the lawsuit -- obtained by TMZ -- he cut a deal with GBG Spyder, which makes active outdoor wear and performance gear. Dempsey claims he did a lot ... personal appearances, slapping the Spyder logo on his race cars, but only got $270,000 before the company stopped paying.
