The 2 Endurance Motorsport Land Rover Defender Sparco Seat Subframes (part B301243-X2) supplies a pair of the B301243 subframes: one driver side, one passenger side, for a full two-seat Defender installation with Sparco bucket seats.
At £82.50 for the pair this is the same unit price as buying individually but saves a separate order for the second subframe. Both are fabricated steel, designed to bolt to the Defender’s factory floor attachment points and present a Sparco-pattern top face above.
The single-subframe listing (B301243) is the right order if you are only fitting one seat. If the passenger seat is a different brand using a different mounting pattern, mix the B301243 for the driver with whatever subframe suits the passenger seat.
For Land Rover 90 or Series 3 floors, check the -LR90 and -S3 suffixed variants; the Defender, 90, and Series 3 do not share the same floor geometry despite sharing a chassis lineage.
Will I fit in this seat?
Send us your height and waist size and we will confirm the fit. how a seat actually feels to sit in is a different question, and our showroom team sit in these seats every day, so call us and we will give you the honest answer.
What does showroom stock mean?
It is physically on our Nottingham showroom floor right now, so you can come and sit in it before deciding. If you want us to hold it for a visit, call ahead and we will keep it on the floor for you.
What do I need to fit it to my car?
The car-specific frame for your vehicle, plus a sliding runner if you want fore-and-aft adjustment. Our guide on base mount versus side mount walks through the whole stack, and tell us your car and we will quote the full kit.
How do I know it will feel right, not just fit on paper?
Makers publish widths and weights, never feel, and two seats with identical numbers can feel nothing alike. We keep the ranges on display in the showroom, you are welcome to come and sit in them, and our head support measurements guide shows the kind of real-world data we collect.
