The Best Way to Install Sub Straps in your Porsche

The CMS Performance Sub Strap Mount is a must-have for Porsche GT2RS, GT3/GT3RS, and GT4 owners using five-, six-, or seven-point harnesses with the factory CFRP Full Bucket Seats (also called Light Weight Bucket seats). Designed to easily bolt in using existing seat hardware without having to fully remove the seats from the car, the CMS Performance Sub Strap Mount properly anchors your harness anti-submarine straps ("sub straps") to your seat base.

The CMS Performance Sub Strap Mount fits the driver- and/or passenger-side seats.

Born In The USA

CMS Performance Sub Strap Mounts are designed, manufactured, and powder-coated entirely in-house in the USA. Made of solid carbon steel while only weighing 1.4 lbs (625g), there's not a stronger, more affordable solution available. CMS Sub Strap Mounts allow full seat adjustment, fore/aft and up/down, while maintaining the ideal sub strap angle to your body for maximum safety.

Custom Porsche Colors Available For Personalized Look

The standard powder coat color of the CMS Performance Sub Strap Mount is a silky-smooth satin black. If you want your sub strap mounts to show a bit of flair, we have color-matched several Porsche paint colors and can powder coat your sub strap mounts in any of those colors for an additional $95 per mount.
