A Planted Technology seat bracket for the Infiniti G20. Part number SB193.
The G20 is the Nissan Primera under an Infiniti badge, which is genuinely useful here: the P10 and P11 Primera are the same cars and the UK parts supply is far better than the Infiniti name suggests.
Send us the registration
This listing carries no year range and the G20 ran across two generations. We are adding the year data. In the meantime a registration takes us a minute and saves ordering the wrong part.
Why a Primera is worth building
The P10 in particular has a multi link front suspension that Nissan developed properly, and the car raced hard in the British Touring Car Championship through the nineties. That history is real and it is why there is still a small following.
The standard seat gives you nothing to brace against once the car is used the way the chassis allows.
Practical
Thirty years old and rarely cherished. Get the carpet up and check the metal before you spend.
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.
