Complete fitting kit: side mounts included. This frame comes with its own side mounts, so any side mount bucket seat bolts straight to it. You only need the seat and the frame, with no separate side mounts to buy. The slider is built in as well, so no separate runner kit is needed.
Belt buckle clip included. This frame comes with a belt buckle clip, suitable for attaching a harness or the car’s factory seatbelt clip.
A PCI Racing sliding sub frame for the BMW Z4, 2002 to 2008. Part number SM-E36-S1-Z4.
The part number is derived from the E36 mount, which follows from the E85 Z4 sharing a good deal with that platform.
Why a Z4 needs thinking about
It is a small roadster with a low roofline and, in most cases with a competition seat, a roll bar behind you. Head clearance with a helmet on is the constraint rather than legroom, so seat height is the number that matters. A purpose made mount gets you down; a fabricated bracket usually adds height rather than removing it.
The slider
The seat moves fore and aft after installation, which suits a car that is still used on the road. PCI’s S1 slider bolts to the base with four bolts where a conventional slider uses two, which they rate as twice as strong.
Construction
Laser cut and CNC formed from a single piece of 1/8 inch carbon steel, gloss black powder coat, grade 10.9 8mm hardware, five and six point sub belt mounting locations built in.
Ordering
Side mount, for a competition bucket, bolting to the factory seat mounting points. Handed, order twice for a pair.
Tell us the seat and your height. In a car this size the shell matters as much as the mount, and we would rather work it through with you first.
