The Bolt-In Door Bars are designed specifically to stiffen the chassis of your Miata. 

The Bolt-In Door Bars are easily installed in all '90-2005 model Miatas in conjunction with any version Hard Dog Roll Bar or even if no roll bar has been installed with minimal interference to normal use of the car.

Additional rear back up plates are required if the door bars are to be used without a roll bar or with our Ace, Deuce or Hard Bar models.

* It is recommended to either add SFI padding to the bar if used with an OEM seat or better yet, use with an FIA rated one piece seat.
