The Racer X Fabrication engine pitch mount for the 2023+ Toyota GR Corolla was designed to reduce engine rotation. The OEM pitch mount uses a fairly soft rubber bushing, which allows for considerable engine rotation under load. While this is great for daily driving, it leaves a bit to be desired under enthusiastic driving conditions. The Racer X engine pitch mount uses a 60A durometer urethane bushing that reduces engine rotation, but maintains a reasonable increase in NVH and in-cabin vibration. The bushing is a perfect trade-off for spirited driving, track sessions and heading out to the local grocery store. The mount itself is CNC machined from 6061-T6 aluminum and anodized black for a pleasing aesthetic appearance, while providing corrosion resistance.
