there are "Type R" kits to the TA05...eg TA05v2-R
or with the earlier car TA05-R & TA05IFS-R; there's also TA05MS
the R kits come with TRF shocks and CVDs,
sometimes stiffer plastics or lower-friction drivetrain.
Regardless if you're going to buy any TA05 to fully hopup with CF chassis etc,
unless you really have to run a TA05 its usually cheaper to buy a TRF417 etc.
^ tell me about it, for the money I spent on getting some extra blue parts from tamiya on my TA06 pro I couldve had a TRF416/7
