This is one big advantage of LiPos, we have the ability to add more weight in complex suspension setups instead of the rudimentary suspension that 1/12 has used for decades.
I still have to wonder if the cars will really go appreciably faster though, Matsukura or Hirosaka could make any car look like a handling breakthrough and I'm not so sure that the added complexity is a good thing. My car handles great and its still the old Associated-style sliding kingpin front end that dates back to before I was born
