It looks like an improvement over the previous one, but you will need to upgrade the quick release adapter.
If your Wheel Base and Steering Wheel have an exchangeable quick release, then yes! Please check the Fanatec website for all the compatibility details.
QR2 is a major improvement over the QR1 in terms of strength, stability, ease of use, and precision fit. You should also find a reduction in mechanical noise while driving, and an improvement in force feedback detail. QR2-equipped wheels can be attached to a Fanatec Wheel Base without touching the spring-loaded sleeve mechanism, making it quicker and easier to start racing. The new design also makes the electronic connection for data and power more secure.
