Thank you. You have rated this product.

BossFrog Miata Door Bars are used to stiffen the Miata chassis in the weakest part of the car the door. Traditional single-tube Miata door bars with two mounting points do little to stiffen the frame The Frog Miata Ribs are mounted in four places the rear bulkhead, the seatbelt mount, and the floor in the center and front so they provide a noticeable change. These Miata door bars are made using smaller diameter 1" tubing so that they fit better in the tight space between the Miata door and the seat.

They are built to retain vertical strength by using a unique I-beam construction with plates spanning the tubing, while allowing full access to the seat controls and dead man pedal. These really do help to stiffen the Miata frame, and will improve the driving feel. See the mounting instructions here.

Wanted to say thanks. The exhaust system fit perfectly, no drone at steady throttle, but a nice sound winding thru the gears. And it does sound a lot like my old Alfa. The Racing Beat lowering springs are just right. Appreciate the tech advice and the service.

The Konig Lightspeeds are incredible. Perfect and the best price in the market. Thanks Chris and Robbie
