The Sparco Evolve junior kart seat for a sim rig, supplied untrimmed. Part number SG0230011.
This is the small shell and it is the point of the listing. Sparco size it for a driver under six feet with a 28 to 32 inch waist, which in practice means a young driver or a small adult. Putting a child in an adult shell and packing it out with foam does not work: they learn to brace against padding rather than against the seat, and the position moves every time the padding shifts.
Untrimmed means the bare shell, with no padding and no cover, exactly as a kart seat is used. In a kart that is normal and it is part of why the seat works. In a rig it gives you the same directness, and you can add padding where you want it.
Specification
Fixed back, black, side mount, no head support wings. Gaming and sim racing rating rather than FIA approval, so it is a rig seat rather than a seat for a kart on a circuit.
Mounting
Side mount, seat only, no brackets. Measure the rail spacing on your rig and we will confirm the fit before you order.
If the driver is going to grow into an adult shell within a season, tell us and we will talk through whether it is worth waiting.
