Viagra for your MX5! A simple piece but a very effective one. These braces slide over the factory frame rails and stiffen the car dramatically. The factory rails are easily damaged over bumps and mistakes when jacking, and every time they are bent the car gets floppier. Flyin' Miata's initial testing showed a 30% decrease in twist and noticed the car felt far more solid when it was being driven. Subjectively, the original test car felt as stiff as a 2004 SE when equipped with these rails. Ground clearance is unaffected and the total added weight to the car is less than 6 kg.

To make your MX5 even stiffer, we highly recommend the FM butterfly brace upgrade as well.

No welding is required for installation although 16 holes need to be drilled in the car. Fits all 1989-2000 cars as well as the 2001-02 cars without the Sport bracing. Sport cars and 2003-05 MX5's can use the braces although one of the factory cross bars has to be removed. The factory bar can be retained with a slight modification. Recently redesigned to make them easier to fit and make them even stiffer. If your factory rails have been damaged, they may need some massaging with a hammer to allow these to slip over top.
