Fact:
Fanatec CSW looks like a german quality product but has two very low quality toy motors,Mabuchi RS555PH, to drive FFB. Each one costs around 2 or 3 euros (yes, its true. Google it).
T500rs doesn't look so cool but has one German industrial quality motor,Bühler 1.13.044.236, driving its FFB. Each motor costs around 100 euros. This single motor has more power than both Fanatec motors together not to talk about quality.
-Thrustmaster has pedals, and a good ones.
-Thrustmaster is 200 to 300 euros cheaper.
-There are a lot of mods including Wheels, Wheel adaptors, good quality loadcells (as oposite to ones found on Fanatec pedals) to thrustmaster that you can buy to upgrade. There's none to Fanatec.
-Fanatec looks much cool and better.............but it isn't.
