Everyone uses an X somewhere...RCX, MRX, TRX, YRX, TNX, DTX, etc. Yes, it does sound like XB8. But no more than anyone else's X's! hehe
The XR/8 made in Taiwan like pretty much everything else out there, even the more famous companies' stuff is made there. GS, however, is not the manufacturer of this particular car. There's only so many ways to design the suspension on these cars, so they all end up looking pretty similar. Interestingly, the front upper arms are being changed to a beefier design.
Also, the shocks pictured are indeed Serpent shocks...the ones that come with the car will have machined teflon pistons and aluminum bodies. It's a prototype, once again...just to give people an idea of the layout of the chassis, mostly.
