The AutoExe Lower Arm Bar suppresses deformation of the pivot (fulcrum) on the lower side of the suspension. In mass-produced vehicles, the bases of the left and right lower arms, which are the base points for mounting suspensions with an open structure, are connected with highly rigid steel or aluminum pipes to suppress unnecessary alignment changes and support accurate handling. Gussets (reinforcing plates) are placed on the mounting surface to equalize the pressure applied to the joint surface. It ensures the highest level of rigidity for a lower arm bar. As for the effect on the minimum ground clearance, which is of concern, the effect on practical use is small because the decrease is suppressed to a maximum of about 15 mm. It is more effective to install it in two stages, upper and lower, with the strut tower bar and floor cross bar.
Features
- Input from the lower arm is transmitted to the cross member, but it is hard to distort because it is reinforced with the lower arm bar.
Notes
- Since the mounting points overlap, it cannot be mounted at the same time as the member brace set.

AutoExe was founded in the 1990s by Yojiro Terada, a former Mazda works driver known in Japan as "Mr. Le Mans" for his record number of starts at the 24 Hours of Le Mans. Many of its staff came from Mazdaspeed, Mazda's own competition department.
AutoExe tunes Mazdas only, and makes aero, suspension, brake, intake and exhaust parts and engine parts, for the MX-5 Roadster and the rotary RX-7 and RX-8 as well as Mazda's everyday models such as the Mazda3 and CX-5.
