For sale there is a 70mm Thrustmaster steering wheel adapter compatible with T300, T500, TS, Rsa and an optional locking ring to lock the wheel on Thrustmaster Bases.

The adapter has 6 bolts at a diameter of 70mm and it is compatible with 3rd party wheels with 6 bolts, 70mm diameter, like NRG, Sparco, OMP, Luisi and Momo steering wheels.

The adapter comes with 6 M5x12mm screws and has 6 M5 nuts already pressed in it to make it easy to mount the 3rd party 70mm wheel on it.

There it is also an option to buy a combo, composed of the 70mm adapter and one locking ring, black or red.

The locking ring matches the shape of the T300 base ring, so you slide this locking ring once and then it make it much easier to rotate the locking mechanism in any direction you want.

I designed the adapter and the ring based on my T300 base, but this must be compatible with other bases that have the same shapes and dimensions.

From my research, this ring should be also compatible with TX, TS-PC Racer, TS-XW, and T500 models, but I tried it only on the T300 model.

The ring goes behind the wheel and it is very little visible and it does not interfere with the wheel at all.

The ring has 12 nudges that are around the exterior and they greatly improve the ease of use of the ring, fitting perfectly to your fingers.

Those parts are build from strong plastic material (PETG - strong thermic and mechanical resistance) on my 3d printer, here in US.

Just choose the model, the color (yes, some are available on Ferrari red color) you want and the quantity and complete the sale.

You will receive only the 3d printed parts ( not the original T300 GT steering wheel - that is in the picture only to show you the assembled aspect)

Those parts are designed by myself, tested on my T300 GT wheel and printed on a 3d printer from PETG material. Design and fabrication are done here in US.

Models:

T300-70mm-adapter - you will receive only the 70mm T300 adapter
T300-70mm-adapter+lock-ring-black - you will receive only the 70mm T300 adapter and the lock ring in black color - this will blend very nice with the wheel, in case you do not want to show-off
