I believe that its about 13mm longer with those...

Stock Revo 2.5 = 317.5 mm
Revo 2.5 with AWAs front position = 327.5 mm
Revo 2.5 with EWCs = 330.2 mm
Revo 2.5 with AWAs rear position = 336.5 mm
Revo 2.5 with AWAs front position with EWCs = 340.2 mm
Revo 2.5 with AWAs rear position with EWCs = 349.2 mm. That's 1.248" over stock!!

......and everything still runs smoothly.
