A Planted Technology seat bracket for the Toyota MR2 Spyder on the W30 chassis, 1999 to 2007. Part number SB227.
The third generation, sold here as the MR2 Roadster. The AW11 takes SB177 and the SW20 takes SB057, and all three are quite different cars.
The lightest of the three
Toyota went back to first principles for this generation: no turbo, no boot, around 1,000kg, and a chassis widely considered the best of the three to drive. It is the purest MR2 and the least loved commercially.
Because it is light, a heavy steel framed shell gives back a real slice of the advantage. Ask us about the lighter options.
Roof down, so think about trim
There is no fixed roof at all. Whatever you fit gets rained on and sat in wet. Ask us about trims that shed water rather than absorb it, because velour in an open car is a mistake you make once.
Space
Mid engined, tight round the shoulders and low. Tell us your height and build before you order.
Have you written anything about this exact product?
Yes, we have covered this exact product: Fitting Sparco Seats Into A Toyota MR2 W30 (MR-S / Roadster / Spyder), and Lexus Planted Technology Frames Updated For 2026. 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 Toyota MR2 Spyder [W30 Chassis] (1999-2007). 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.
