Show original supplier description
The CMS Performance Sub Strap Mount is engineered to be a vital safety upgrade for Porsche owners utilizing factory CFRP Full Bucket Seats (LWB seats) in models such as the 992 GT3/GT3RS, 991.1 & .2 GT3/GT3RS, 991.2 GT2RS, 981 Cayman GT4, and 718 Cayman GT4. Constructed from solid steel and finished with a durable powder coating that matches the OEM seat base, this sub strap mount prioritizes safety and longevity. Despite its robust construction, it remains lightweight at only 1.4 lbs (625g). The design ensures that full fore/aft and up/down seat adjustability is maintained, crucial for driver comfort and proper harness positioning, thus optimizing safety angles for the anti-submarine straps. Installation is straightforward, and the mount is compatible with OEM seat belt and airbag hardware. This component is manufactured entirely in-house in the USA, reflecting a commitment to quality control and domestic production.
