Two Schroth Lotus II ASM four-point harnesses in black, driver and passenger together as parts 91158-0 and 91159-0. These are the standard Lotus-specific harnesses without the flexible end fittings of the Lotus II-FE version at 91158A-0/91159A-0. Both versions are designed for the Lotus Elise S1 and S2 and the Exige S1 and S2.
Four-point competition harness with Schroth’s ASM anti-submarining system, designed to route through the specific structure of the Elise and Exige chassis. Three-inch shoulder belts, 2-inch lap belts, clip buckle. FIA 8854-1998 homologated. Bolt-in installation. NOT HANS compatible.
The difference between this listing and the Lotus II-FE ASM pair (91158A-0/91159A-0) is the end fitting: the standard Lotus II uses a fixed straight end plate that requires the harness anchor point to align squarely with the strap run. The FE version has an adjustable end fitting that angles to suit mounting points that are not at a straight-pull angle from the strap. If your Elise or Exige mounts are straightforward, the standard Lotus II is adequate. If the mounting geometry in your specific car causes the strap to exit the anchor at an angle, the FE version is the more forgiving installation.
Both come as the full driver-and-passenger pair. Black only in this listing. If you need red webbing, the Lotus II-FE ASM pair is also available in red. The Sport Seat Position attribute confirms RHD driver (91158-0) and RHD passenger (91159-0) are both included.
FIA 8854-1998 is the four-point competition standard. For Elise and Exige owners competing under series rules that require a six-point harness, the four-point Lotus-specific harnesses do not meet that requirement; a universal six-point would be needed instead.
