The GrimmSpeed Master Cylinder Brace is engineered to eliminate the excessive firewall flex found in many Subarus—one of the biggest causes of soft, inconsistent brake pedal feel. By reinforcing the master cylinder with a rigid, multi-point support system, this brace delivers a firmer, more responsive pedal, similar to the improvement you’d expect from stainless braided brake lines.

Built from CNC laser-cut 12L14 steel and finished in a durable black powder coat, this brace is designed to take abuse, resist corrosion, and outlast the car it’s installed on. With four factory strut-tower mounting points—the most of any brace on the market—it provides unmatched stability without requiring any cutting, trimming, or modification to OEM components. A simple Allen-key locking mechanism ensures quick and secure adjustment.

• Most Mounting Points Available: 4 factory strut-tower mounting locations for maximum strength
