hehe, I try my best to get some of the setups, in fact I have this years DHI one sitting on my desktop that I need to upload.
Thing is, in all honesty, not a lot changes geometry wise on the cars at the big meetings...but stuff like shock position, camber link shims etc can generally be easily picked up off the photos.
Most difficult thing is figuring out what's being run in the shocks...
Believe me, I wish there was more reporting on the setups too, but have to make do with the hand we're dealt, after all the TRF side is microscopic compared to the rest of what Tamiya does, unlike HB, Xray etc.
