Factory seat belt kept: this frame comes with a clip for the factory seat belt buckle, so your original belt stays in use, including with a side mount seat such as the Cobra Nogaro on Cobra side mounts.
Direct fit subframes for the BMW M3 E46, bolting onto the car’s original seat mounting points.
You are already starting from a good seat
An M3 seat is not a standard 3 Series seat. It has more bolstering and, on many cars, adjustable side support, so the gap between what you have and what a bucket gives you is narrower here than on an ordinary E46.
What a bucket and frame still give you is a lower hip point and support that does not move under sustained load. If neither of those is the problem you are solving, you may be better keeping the M seat and spending the money on the belts or the tyres. We would rather say that than take the order.
What you get
Base frame and sliding runner, included in the price. The other five makers sell the runner separately.
What it will take
Cobra base mountable buckets and reclining sport seats with a 291mm or 405mm wide handle. Motorsport seats and the Nogaro need side mounts adding to the order.
Tell us the seat at checkout. Priced per frame, which fits one seat.
