The New updated T-Plate designs offers overall increases traction compared to a Link-Type set up. That's straight from the Tamiya Product Development team.
The T-Bar provides a progressive roll damping effect superior to that offered
by the spring-actuated side links on the TRF101. The roll point ball has been
placed in as low a position as possible, in order to maximize damping effect.... 2 thicknesses of T-bars (planned as 1.5mm and 1.8mm) will be included with the kit.
The brand new pitch axle gives vastly improved, independent pitch damping,
letting the chassis deal much more smoothly with undulating surfaces.
The roll damper has been moved closer to the lower deck, giving a more compact rear and contributing to the chassis' low center of gravity.
I have images of how all this works, but I can't show them just yet. Sorry. Strict confidentiality agreements and all.
Also, the MSRP of this new kit is significantly less than the TRF101.
