I'm guessing that your using modern steel belted radial tires.

I think I'd suggest a larger than stock diameter front sway bar. Skip the rear sway bar. If you really must have a rear sway bar, use smaller than stock diameter. A rear sway bar that's to large will cause the rear to bounce a little over bumps at speed, which is not desireable for either traction or control.

After your done with the sway bar, consider larger diameter torsion bars and good shocks. After that, frame stiffening. (check out the XV motorsports website).
