The M2 Motorsport GTR XL is the large-fit version of M2’s composite Alcantara bucket seat. The standard GTR is a medium seat targeting a 34-inch waistline; the XL extends the dimensions throughout the shell for drivers who need more room in the hip and shoulder area.
Part number M2-RSGTRXL-B1B1. The shell is fibre composite, trimmed in full Alcantara. Side mount holes at the standard 290mm spacing, six-point harness slots built in. The key dimensions from M2: rear squab width 41cm between the knees (uncompressed), front squab width 45cm at the widest hip point, overall wing width 60cm, overall seat height 101cm. The XL includes a head support at the top of the backrest, which the standard GTR does not have.
The GTR XL fits M2 Motorsport’s vehicle-specific sub-frames by reversing the up brackets. This is a straightforward adjustment when fitting: the up brackets are the height-adjustment components that sit between the sub-frame and the seat, and reversing them changes the seat’s height relationship with the frame. No extra parts are needed.
Sold as a single seat. Brackets are not included. You will need the vehicle-specific M2 sub-frame for your car separately.
The standard-size GTR is at M2 Motorsport GTR Alcantara Composite Fixed Bucket Seat. The GTS uses the same composite construction but with a woven textile back rather than full Alcantara, at a lower price point. If you are unsure between the three, call us and we can go through the dimensional differences against your height and build.
