Mazda RX7 FD3S Rear Subframe Reinforcement Mounting Brackets

FD RX7's prior to 1994 lacked the additional subframe bracing that was available on later model years. They can be added (either factory tubular braces, aftermarket like Autoexe, or our JP3 Tubular Reinforcement Cross Brace set), but in order to do so, additional mounting points need to be welded on the rear subframe. There has been no bolt-on option until now!

These rear subframe mounting brackets are CNC laser cut and bent 10 gauge steel. The corner folded seam is TIG welded for a boxed out gusset. They are mounted via existing holes on the rear subframe (see photos and video) using the provided grade 10 M12 hardware. The enduser has the option to weld these in if so desired.  

These brackets can be utilized with our rear meth pump and fuel filter mounts, however these mounts need to have their mounting holes reamed out to accommodate the M12 hardware. 

NOTE:  This listing is for just the reinforcement mounting brackets - tubular cross bracing in photos/video are sold separately.

Product feature list:

• CNC laser cut and bent 10ga steel 
• TIG welded corner gusset for added strength
