A Planted Technology seat bracket for the Honda CRX, 1988 to 1989, excluding the Si. Part number SB173.
Read the exclusion
The Si of these years takes a different bracket. Check what you actually have rather than going by the year, and send us the registration if you are not certain. These Honda year windows are narrow and this is where people order the wrong part.
We also list the 1984 to 1987 CRX under SB304 and the 1990 to 1991 car under SB167.
The second generation CRX
Double wishbone suspension at both ends and around 900kg. It is one of the lightest cars anyone puts a competition seat into, and that weight is the entire basis of how it drives.
Which means the seat choice genuinely matters. A heavy steel framed shell gives back a significant proportion of what makes the car quick. Ask us about the lighter GRP and composite options before you default to the cheapest steel seat.
Practical
These rust and almost all have been modified. Get the carpet up 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 made for the Honda CRX [Excluding Si] (1988-1989). 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.
