and here are the bac ones also avaliable in white http://www2.towerhobbies.com/cgi-bin...p?&I=LXDW25&P=

These wheels are way stronger than stock

And as for the supercharger and trx 3.3...The idea of supercharging does not really work on 2 stroke engines and from what I have heard they provide little performance gain. However a trx 3.3 would give u a big performance gain but it would not be a direct fit you would have to get many new parts and modify sevral things.
