roll bars

what does it cost to have roll bars installed? can one do it oneself? if so, where could i purchase them? please respond to slipguy@aol.com thank u rob

It all depends on what you want the roll bar for and how you're using the car. I've seen them as cheap as $400, and the full roll cage in my car is about $3000. Welded is more expensive, a lot stronger, and a lot harder to remove.

Hard Dog has the best "rollbars"
If you want to spend a little more and get a safer bar, I would recommend that. If all you want is looks, I would suggest a Frenzy Bar. (http://www.frenzybars.com)

Looked at your Frenzy site says they are "style"bars not a roll bar. Style bars a beauty enhancements that stiffen chassis more. Roll bar is a safety item that could save a life if that unfortunite day happens when tires say hello to the sky. For a street car I would recommend company such as Hard Dog Bars
