I have the Traxxas sways on both my E and nitro Revo. Yes, you do have to drill the rear rockers but other than that they are great. I didn't try the Tekno sways (considered them for my nitro Revo) because I did not like how the rears mounted (already a pita to get at the rear shocks as it is) and did not what to have to deal with possible clearance issues with different motors.
