I was lucky to get my hands on some of the prototypes. Lol. Actually I've been messing around with the TQ big bores (which are cosmetically very similar to AE). You will notice Hartson has a longer screw on the front tower, mainly b/c I found you need to space them back about 2mm so they don't rub. The rears fit fine, but I run a 1mm spacer on the bottom to prevent it from rubbing on the link. I have been runnin KYO springs and losi pistons in mine.
