More Steering w/ 2 servos

[InsaneRC]

ok i do not have the money yet to upgrade to a single servo set-up in my e-revo and i have the 2 stock e-revo servos & i was wondering how to get more steering, i have the maxuim travel stop in there but doesn't seem to help @ my track (picture of the two coners i have trouble on attached)

My friend suggested to me to take out the steering stop and cut off the stops and set my end-points......any suggestions?
