I think the BB shocks were the main driving force. The rest of the upgrades are meh. If you want people to switch from losi to Ae and tell them hey buy my car for $250 and then buy my $100 shocks, then realize you cant sell your v2 shocks because everyone wants the BB shock. Then, less people will want to switch. Once the came out with the BB shocks, then needed to release a new "dot" revision. But they took it a step further and gave you every upgrade you were using and wanting. I think they did the right thing. This was the best thing they could do to try and bring drivers over to AE. Buy my car with all the upgrades, just add tires and go. I wish more companies sold cars that were loaded out of the box.
