Rig and Seat Compatibility

The SIMRIG SBM is compatible with most sim-racing rigs and bucket seats. If you have an aluminum extrusion rig and a bucket seat with two shoulder openings, everything is likely good to go. However, there are a few things to keep in mind.

Watch our quick introduction video on YouTube.

The rig

The SIMRIG SBM needs two mounting points on your rig: size M8, spaced 200 mm apart. It is designed to attach to slot-8 type-I aluminum extrusions. Most sim racing cockpits are made from this stuff. The slots should face either upwards, or to the rear.

The seat

We recommend a bucket racing seat with a hard shell on the back. The SIMRIG SBM works best with a firm surface to rest against.

Where the harness lands on your body is a direct result of seat geometry. Your shoulders must line up with the holes at the top of the seat. The hip straps and crotch straps are likewise controlled by the seat. A seat that fits your body is therefore necessary.

Bucket seat

  1. Shoulder straps are required.

  2. Your shoulders must line up with the shoulder strap openings.

  3. Hip strap openings are required for four-, five-, and six-point harnesses.

  4. A crotch strap opening is required; unless a four-point harness is used.

Formula seat

  1. Shoulder straps are required.

  2. Your shoulders must line up with the shoulder strap openings.

  3. The hip straps go over the sides.

  4. In this example, there is no opening for the crotch strap: use a four-point harness (or a five-point harness without the crotch strap.)

The harness

Note

The SIMRIG SBM includes a two inch wide, five point, sim racing harness in black. The included harness is not approved for automotive use.

The maximum harness strap width is 3 inches. Recommended width is 2-3 inches.

The SIMRIG SBM is compatible with four-, five-, and six-point harnesses.

The harness attaches to the SIMRIG SBM with hooks or loops.
