You're on stock FE4 bars right now?
If so, and you're running somewhere between 100TW tires and Hoosier R7's, you want the Hotchkis front bar and the BMR adjustable rear bar. Start with both on the middle setting. This will maintain the neutral balance, but provide 30% added roll stiffness from FE4 bars to match the added tire grip.

I don't recommend the BMR hammertone powder coat, as it will end up rusting after the first contact with water.
