Cap stuck on Racing Hart C5. Help!

I have Racing Hart C5 rims and the cap on it is stuck. You have to remove the cap to remove the wheel. I've tried bringing it to the shop, but after using big vice grips they still won't budge. Anybody have any ideas, or anybody you know can help?

I'd recommend having one of our local installers take a look at your car. We're very picky about who we list as one of our recommended installers so you will be able to speak to an expert. Please go to the follow link and enter your zip code to find the closest one:
