Description

The AutoExe Member Brace Set is a chassis reinforcement system designed for the BK3P Mazdaspeed 3. Constructed from steel with a red finish, this set includes front and rear braces to reinforce the open-structured floor, center tunnel, and lower fuel tank area. It aims to reduce floor vibration and kinking, allowing for proper function of the front and rear suspensions. When combined with a tower brace set, it creates a two-stage high-rigidity body.
