Complete fitting kit: side mounts included. These frames come with their own side mounts, so any side mount bucket seat bolts straight to them. You only need the seat and the frame, with no separate side mounts to buy.
This listing is for a matched pair of M2 Motorsport direct fit sub-frames for the Toyota Supra MK4 A80, covering one driver-side and one passenger-side frame in a single purchase. Part numbers M2-21080-0000 (driver and passenger, bought together). The JZA80 was built from 1993 to 2002 with the 2JZ-GTE twin-turbocharged straight-six.
If you are doing a full interior seat swap on an A80 Supra, buying both frames here is more straightforward than placing two separate orders. The two sub-frames are the same steel part: both bolt to the OEM floor mounting points without drilling, both carry 290mm side mount holes, both take the same range of compatible bucket seats.
For the full specification and vehicle-specific notes, see the individual listing: M2 Toyota Supra JZA80 Direct Fit Sub-frames.
Choose base mount or side mount fixing at the top of the page. Side mount fits any bucket with 290mm side holes: Recaro, OMP, Sparco, Bride, Corbeau, Cobra, Takata, MOMO and the rest. Base mount works with under-seat mounted seats.
