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 E46 3-Series, 1999 to 2006. Part number SM-E46-S1.
E46s get seated more than almost anything else we sell mounts for, and this is one of our best selling PCI parts as a result.
Why the E46 in particular
The standard seat sits you high and lets you move about in it, and an E46 being driven properly asks a lot of both. A competition bucket on a purpose made mount fixes both at once, on the floor points BMW already provided, so nothing is drilled.
The slider
This is the slider version, so the seat moves fore and aft after installation. PCI’s S1 slider bolts to the base with four bolts rather than the two a conventional slider uses, which they describe as twice as strong as two bolt mounting.
If the car is a dedicated track car and you want the lowest fitment, ask us whether an adjustable mount is made for the E46. It sits lower and costs less, at the price of the seat no longer moving.
Construction
Laser cut and CNC formed from one piece of 1/8 inch carbon steel, gloss black powder coat, grade 10.9 8mm hardware, with five and six point sub belt mounting locations built into the mount.
Ordering
Side mount, for a competition bucket. Handed, so order twice for a pair, or take the pair listing.
