Ultra Racing 4-point front strut brace for Mazda MX-5 MK4 / ND models with the compatible factory front tower-brace mounting arrangement.
This Ultra Racing front strut brace is designed as an aftermarket chassis reinforcement upgrade, linking key mounting points across the front suspension towers to help reduce unwanted chassis flex and improve consistency through the front of the car.
The TW4-3717 uses Ultra Racing's one-piece welded steel construction and a four-point mounting layout. By reinforcing the upper front chassis structure, the brace can help improve steering response, suspension consistency and overall chassis feel during cornering, braking and directional changes.
