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 Subaru Impreza GRB, one driver-side and one passenger-side in a single purchase. Part number M2-2H015-0000, the same steel frame as the individual listing, bought together for a full front seat installation.
The GRB WRX STI (2007 to 2011, EJ257, 300bhp) is the third-generation Impreza body in the WRX/STI lineage. Different floor mounting from the GC8, hence a separate M2 rail.

Have you written anything about this exact product?
Yes, we have covered this exact product: Mirco GT 3D Seats Fitted Into a Subaru Impreza GRB. 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 Subaru Impreza GRB. 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 M2 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.
