Thank you. You have rated this product.

BossFrog Miata Frame Rails! If you have ever jacked the car up on the frame rails, then you know how easily they bend and deform. These steel rails slip right over (under) the stock frame rails and bolt into place through the floor to provide additional stiffness where it counts. We have added lightening holes on the bottom surface but the sides (where you need it) are full strength. Kit includes " grade 8 hardware and mounting instructions, and requires drilling of 20 holes through the floor. Fits 90 05 Miatas, but sport bracing may need to be modified to fit.

Flat Rate shipping of $25 total will be applied after order is complete on this item for all shipments in continental USA.

I received the Roadstersport II, and I wanted to compliment you guys on an awesome product. The Miata should have these on from the factory. They make a great sound, that is not obnoxious at all. The exhaust also installed seamlessly!!! I will buy all of my Miata stuff from you in the future. Thanks,

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