A Planted Technology seat bracket for the Honda CRX, 1990 to 1991. Part number SB167.
A narrow window. The 1984 to 1987 CRX takes SB304 and 1988 to 1989 takes SB173. Ordering from the wrong window is the commonest mistake on Honda fitments, so send us the registration if you are near a boundary.
The second generation CRX
Double wishbone suspension at both ends, around 900kg, and in Japanese SiR form the B16A with VTEC. It is one of the most complete small cars anybody has built and it remains competitive in club events thirty five years on.
In Europe there was also the CRX with the glass roof, which is a different proposition again for headroom. Tell us which you have.
Weight is the argument
At this weight a heavy steel framed shell is a meaningful proportion of the car. Ask us about the lighter GRP and composite options and take it seriously.
Practical
These rust and most have been modified by previous owners. Get the carpet up and look properly.
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.
