EVS Tuning Master Cylinder Brace is made of 6061-T6 Aluminum billet. It mounts onto the inboard side of the shock tower housing and prevents the brake master cylinder from moving forward (caused by flex in the firewall and brake booster) when excessive pressure is applied to the brakes under hard driving conditions, such as road racing and autocross. The overall result is a greatly improved brake feel and sensitivity, therefore reducing brake fade even for everyday street use!

Silver or anodized red color options Fitment: 92-95 Civic EG and 94-01 Integra 96-00 Civic will require drilling and longer main bolt for usage. .
