Highest Quality Accessories for Miatas & MGB's

The most important reason for a Boss Frog rollbar is safety. Boss Frog customer Paul Bishop was recently going around a very familiar corner on a cold day with cold tires, when his Miata went into a snap oversteer. The car skidded sideways and hit soft dirt on the edge of the road, flipping the car. The car ended up on its top, and Paul was able to crawl out from the overturned car with just bumps and bruises. Paul credits the solid rollbar with saving his life, and his advice is to lower your speed on corners when the weather is cool.
