I know I'm kinda in the wrong forum since I drive a mazda...but plenty of my friends race older civics and CRXs. Theres plenty of sponsorships...from mom and pops to big shots once you rack up the wins...I've got a sponsor for tires next season from a friends shop, its not a lot, but it gets me going somewhere. As for you guys...take a crx...throw some tires on it..some sways...and if you can afford it, suspension mods. And go at it, mostly its for fun, but theres a lot more interest in auto-x than many people believe.
