CMS Performance Racing Seat Side Mounts

CMS Performance Racing Seat Side Mounts provide a strong, the most highly adjustable solution for mounting compatible side-mount racing seats while also incorporating dedicated mounting points for your racing harness lap belts. No other side mount allows for more adjustments than any other side mounts on the market
Available in both Short and Tall versions, these mounts give drivers and builders the ultimate flexibility to fine-tune seat height, rake, and overall driving position while simplifying the installation of the lap portion of a multi-point racing harness.
Integrated Racing Harness Lap Belt Mounting Points
Unlike basic racing seat side brackets, the CMS Performance Side Mounts incorporate dedicated attachment points for the left and right lap belts of a compatible racing harness. This helps create a cleaner, more integrated seat and harness installation without requiring separate universal lap belt brackets.
The lap belt mounting locations are built directly into the seat mounting system, keeping the attachment points close to the seat and helping provide proper harness routing across the driver's pelvis.
Choose Short or Tall Side Mounts
Short Side Mounts: The Short version features a compact profile for installations where less vertical mounting range is required. It is an excellent choice for lower seating positions and tighter cockpit installations.
Tall Side Mounts: The Tall version provides additional vertical adjustment range, giving you more flexibility when setting seat height, seat rake, and overall driver position.
