I was refering to the trend of using narrower suspension blocks (X blocks) and running less toe-in at the hub on the 415's (ala HPI)
Not sure if the Worlds conversion (blocks) would work well with the EVO because of the lower hinge pin location on the blocks (1mm?)
You could use the EVO X blocks and the new 0' rear hub for similar effects....maybe?
I guess time and testing will tell
