The BS5 is a reclining seat with a fibreglass-reinforced backrest on a steel frame. Part number SS34Z, sold singly, black fabric only. It combines the adjustment of a recliner with more back-panel stiffness than a purely steel-framed seat, because the backrest shell is reinforced with GRP behind the trim even though the main frame underneath is steel.
Sized for drivers under 6ft. Waist size is all sizes, so the height restriction is the only physical limit. Weight is approximately 16kg, which is the heaviest reclining seat in the 345mm range by some margin. If reducing cabin weight is a consideration, the Eco at 13kg is lighter.
The fibreglass-reinforced backrest keeps the panel from flexing when loaded in cornering, which is the functional difference from the standard steel-framed recliners. The BS2 (SS42) also has a fibreglass-reinforced backrest; it has no height restriction and is available in vinyl or grey fabric. The BS5 is under 6ft only, and black fabric only. If the BS2 fits the driver, it is the one to choose, with the same backrest construction. The BS5 is for drivers under 6ft who prefer the BS5 shell profile.
Base mount, 345mm x 280mm bolt pattern, sliders included. Reclining, double-sided adjustment. Road and Track approval. No headrest. Works with a 4-point harness.
