Product Overview

Reinforced sway bar brackets for the NA/NB chassis by AWR Racing.

Made in the USA, laser cut and CNC folded, mig welded steel units. Powder coated black for a super durable finish. All units are provided with AWR's lifetime warranty. These redesigned sway bar brackets for the 1st gen Miata(NA) are now the same part for 2nd gen Miatas(NB). A slight revision in the bolting dimensions allows for the use of more aftermarket sway bar clamps. These brackets fit cars with and without power steering. Open ended reinforced sway bar brackets allow the option of putting power steering hoses through the bracket.

In racing and autocross use, especially when using larger sway bars and driving aggressively, the stock sway bar brackets can flex to the point of breaking. These reinforced brackets replace the stock ones to eliminate this problem.

These revised units will accept OEM sway bar clamps, Racing Beat aluminum sway bar clamps and Energy Suspension sway bar kits.

NOTE* Spot welds attaching the stock mounts to frame must be drilled out.

customer feedback:

"I installed the brackets on Sunday and got the car running on Monday. I cannot thank you enough for designing such a great product like this,
It seriously gave the lost driving characteristics back, no more unexpected oversteer, no more floating sway bar, no more mysterious clunks going over speed bumps. Thank you AWR  I will highly recommend these brackets to all the fellow Miata drivers that don't know about these yet or are contemplating buying and installing them. Definitely going on my next Miata regardless if the stock brackets are good still. Thanks AWR Racing keep up the amazing work."

Warranty Information

AWR believes so strongly in our engine mounts and sway bars that as of May, 2008 we are now backing them with a limited Lifetime Warranty. What’s more, this warranty, excluding bushings, is retroactive to all mounts built previously by AWR. Basically, if it breaks or fails, we’ll fix or replace it at our discretion. The warranty is ‘limited’ in that bushings are considered a normal wear item, so the urethane or rubber bushings are not covered, but if the metal cracks, breaks or otherwise fails, we’ll replace or repair it. As of now, there are no warranties, either expressed or implied for any other items.

    Reinforced Sway Bar Brackets - 1990-2005 Miata

    Posted by Scott Swartz on 23rd Oct 2018

    Once I removed the OEM brackets, installing the new brackets were straightforward. They fit just a little tight, which is good. Once lined up with the OEM holes they bolted right in. The car felt tighter and more responsive after installing these. I will never have to worry about these breaking like the OEM brackets.
