What also contributed to me posting this is due to the fact all of Tamiya's flagship 4WD 1/10th scale buggies come with the standard universals. Correct me if I am wrong but I believe from the DB01R, TRF501X, TRF501X WE, TRF511 and the TRF502 all come with standard universals - if the WO universals are performance enhancing over the standard would they not come with the TRF models?
