Product Description

This three piece under body brace kit is a replica of the long-ago discontinued Mazdaspeed braces for the NC MX5. These braces were popular for their very low-profile design offering good ground clearance.
Made in the USA, all TIG welded aluminium for ultra light weight AND strength.

NOT as comprehensive as our RoadsterSport 6 piece underbody brace kit, but the slimmer tubing used in this design offers better ground clearance.

This 3 piece kit includes 2 Rear Sub frame Triangle Braces and a Centre X Brace. Does not replace the factory "K Brace" under the transmission; you will keep that factory brace in place.

Mazda designed/intended these braces for a car with the stock exhaust, so there are some complications and notes if trying to use an aftermarket midpipe with these braces.

Aftermarket midpipe notes:
Those with our RoadsterSport midpipe: While our RoadsterSport midpipe does clear this bracing, the positioning of the bung for the secondary o2 sensor after the cat in the midpipe results in the sensor hitting the brace. So if you have not moved your o2 sensors down to the midpipe then you will not have any issues. But if you do need the secondary o2 sensor down in the midpipe, you would not be able to use the provided bung. Instead you'd need to have a bung welded in a different position.


We cannot guarantee fitment with aftermarket midpipes and catalytic converters from other brands.
