A Planted Technology seat bracket for the Infiniti Q50, 2014 onwards. Part number SB306.
The Q50 is the Nissan Skyline V37 in Japan. If you have an imported V37, send us the chassis number and we will confirm the fitment.
Direct Adaptive Steering
Worth knowing about, because it changes the case for a good seat. Infiniti fitted the first production steer by wire system to this car: on the cars that have it, there is no mechanical connection between the wheel and the rack in normal operation, and it was widely criticised for feeling remote.
With less coming through the wheel, what you feel through the seat matters proportionally more. If your car has that system, a seat that holds you and transmits what the chassis is doing is not a luxury.
The Red Sport
The twin turbo VR30 is the version worth building, and it is quick enough that the standard seat becomes the limit.
Side airbags, occupancy sensing, powered adjustment and heating. Tell us the specification.
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 made for the Infiniti Q50 (2014+). Chassis code and years matter more than the badge, as floor pans change between generations, so if your car sits near a changeover year, 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.
