Direct fit subframes for the BMW 3 Series E90, built to bolt onto the car’s original seat mounting points. Part number COBPE77E327.
A fitting frame is the vehicle specific base that replaces the standard seat runners. The seat then mounts to it, directly or on side mounts, and the frame is what decides your final seat height and how far back you can sit.
The runners are included
The sliding runner comes with the frame rather than being an extra, so you keep fore and aft adjustment.
Check that against the other quotes you have. Sparco, Planted, OMP, Recaro and Corbeau all charge for the runner on top, which means the frame prices are not comparing the same thing until you add it in.
What changes when the standard seat comes out
An E90 seat is heavy, electrically adjusted on a lot of cars, and tied into the airbag and occupancy sensing. Taking it out has consequences beyond the bolts, so work out what the car needs before you start rather than after the seat is on the garage floor.
Raise it with us if the car is staying on the road. It is the part of a seat swap that catches people out, and it is easier to plan for than to unpick.
Before you order
Built around the Cobra seat range, so a seat from another maker is a cross compatible component rather than a designed pairing. Send us the model and we will check it.
Base mount at 291mm x 330mm, the standard Cobra pattern. Priced per frame, which fits one seat.
