The TR Move Universal motion platform with four D-BOX GEN 5 4250i actuators is an expensive product, but if you can afford it, it's well worth it. It adds a lot of realism to the driving experience.
The problem I encountered was adapting the Alpine TRX cockpit to the motion platform. The motion platform's manual is confusing, not very detailed, and also contains some errors and inaccuracies. I had to figure out how to properly screw together some parts and brackets. The entire assembly, including the cockpit and the motion platform, isn't simple and can't be done by just anyone. It requires some ingenuity, improvisation, and a bit of DIY skills.
Once the assembly was complete, I tested the entire setup driving GT vehicles and also rally vehicles (jumps, bumps, curbs, etc.). The result is that the entire assembly, the cockpit and the motion platform, respond correctly and as expected. I haven't noticed any flexing or any noises or squeaks.
Otherwise, the handling with Trak Racer during the assembly process was satisfactory. Shipping of all the products I placed in two orders was also fast. In short: despite the aforementioned problem, it's a good product that I recommend.
