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. Very odd shaped item and shipping charges may vary...feel free to email us your address for confirmation.

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

As you can see, i placed another order for more parts for my car. I wanted you to know that I'm pleased at how quickly the wheels/tires came, and the radiator too. Great service and response time.

Hey Brian, Recieved my Borla Dual Muffler Sport today from Fedex, and installed it in about 30-45 minutes. An Outstanding product with absolutely no drone throughout the power band, it sounds powerful, not at all like one of the ricey "fart tubes" that can be found elsewhere online. It has perfect like OEM fitment. Great prices, and great products. Product was shipped promptly and arrived as ordered. Would buy again!
