The GSI AH100 is a 100 mm wheel hub extension in billet 6061 aluminium for sim racing, with a 70 mm PCD bolt pattern on both faces, designed to bring the wheel closer to the driver and fine-tune the driving position.

It sits between the wheelbase quick release and the steering wheel, adding 100 mm of reach without giving up rigidity. Its dual hole pattern — one face with six threaded holes, the other non-threaded — lets you pair virtually any wheel with any base that follows the 70 mm standard. Every unit is CNC-machined from solid aluminium billet and colour anodised.

Key features of the GSI AH100

100 mm shaft extension to correct the distance between base and wheel in deep cockpits.
70 mm PCD pattern on both faces, the standard used by most high-end direct drive wheelbases and sim racing wheels.
One threaded face and one non-threaded face for complete freedom when mounting.
Billet 6061 aluminium, CNC-machined and finished in coloured anodising.
Just 0.16 kg, a negligible weight against the inertia of the wheel and base assembly.
Supplied with six M5 × 12 mm screws for mounting.

Compatibility

Works with any sim racing wheel or base using the 70 mm PCD (6 × M5) bolt pattern.
Designed around GSI wheels, but compatible with any wheel that follows the 70 mm standard.
It is a passive mechanical accessory: no electronics, no software or firmware required.
Check your quick release pattern before ordering: if your base or wheel uses a PCD other than 70 mm you will need an additional adapter.

Frequently asked questions

Which bases and wheels is the GSI AH100 compatible with?

With any wheel or base using the 70 mm PCD bolt pattern with six M5 screws, which is the standard on most high-end direct drive wheelbases. The AH100 carries that pattern on both of its faces.

What is the difference between the AH100 and the AH50?

Only the length: the AH100 extends the shaft by 100 mm and the AH50 by 50 mm. Material, 70 mm PCD pattern and hole layout are identical. Choose the AH100 if the wheel sits too far away in a deep cockpit, and the AH50 if you only need a small adjustment.

Does it include the screws needed to mount it?

Yes, every AH100 ships with six M5 × 12 mm screws. Those screws serve the threaded face of the hub; for the non-threaded face you will need the hardware from your base or quick release.

Why is one face threaded and the other not?

So it can be mounted either way round. The threaded face takes screws directly, while the plain face lets the screws pass through to whichever part carries the thread. That way the same hub covers very different wheel and base combinations.

Does adding the AH100 affect force feedback?

It weighs 0.16 kg and the billet 6061 aluminium construction introduces no noticeable flex, so the effect on force feedback is minimal. It does slightly increase the leverage relative to the base shaft, which is most noticeable on high-torque wheelbases.

Which colours are available?

At Simufy you can choose between black, red, blue, gold, green, purple and Gun Metal grey, all in an anodised finish. Pick your colour from the selector on this page.
