A Planted Technology seat bracket for the BMW M6 coupe on the E63 chassis, 2005 to 2010. Part number SB350.
The E63 M6 has the S85 V10, revving to 8,250rpm, and it is one of the more extraordinary engines BMW have put in a road car. It is also a heavy grand tourer, which shapes what you should put on this bracket.
The seats in one of these are complicated
An M6 of this generation can have powered adjustment in several planes, active side bolsters that inflate as the car corners, heating, memory and airbags. There is a great deal of mechanism and wiring in a single seat and removing one is a proper job rather than four bolts.
Tell us the specification before you order anything and we will work through what has to be dealt with. Done badly, the car will complain afterwards and the airbag system can end up in a state it should not be in.
What you are actually gaining
Not weight. In a car this heavy a steel framed shell will not move the scales. What changes is that you stop sliding about when the car is loaded up, which on a V10 M6 happens sooner than the size suggests.
Handed, so order twice for a pair.
Have you written anything about this exact product?
Yes, we have covered this exact product: Lexus Planted Technology Frames Updated For 2026, and Customer Car: Subaru Impreza With Corbeau RRS Seats and Planted Technology Brackets. That is first-hand coverage from our own builds and showroom, not brochure copy.
Will this fit my car?
This frame is car-specific, so match the vehicle in the product name to your exact car and generation. If you are unsure, send us the registration and we will confirm before you order.
Which seats does it take?
Check the bolt pattern in the specification against your seat. The Compatible seats tab above lists what bolts straight on. If your seat is not listed, tell us what you run and we will confirm the fit.
Do I keep fore-and-aft adjustment?
Only with a sliding runner between the frame and the seat, which is a separate part on Planted frames. If more than one person drives the car, budget for the runner. Our guide to sliding runners explains the options and widths.
Is this for the driver or passenger side?
Both sides are available on this listing, pick driver or passenger side at the point of order (sides listed are for right-hand-drive cars). Left-hand-drive car? Ask us, as the sides swap over and availability varies by model.
