Hmmmm. The Evo 3 has almost everything. Is it for the look or is it to gain an extra lap?
For corner speed, I'll suggest you consider a fast steering servo. It's often a overlooked hop op, yet very important. I dont know what else you got, so what about tuning options, like rear toe-in hubs, extra sway bars, springs....
