i believe that you will have to order overseas. there is nobody in the us who imports tech racing gear.
the car will cost as much as a 415, but still has plastic bulkheads, and no diff for the front of it. although, i do not believe a diff has been issued for the tamiya kit either.
something else that the 415 fixes is that they tied the motor mount into the bulkhead that holds the layshaft. the tech car has a dedicated motor mount that mounts only to the lower chassis. it is subject to flex or movement in general relative to the layshaft. spur gears will likely be replaced more often than with the 415.
it is a pretty car though, but not as pretty as the my02-r.
