2004-2006 GTO Front suspension

[Windsor GTO]

OK, so currently my 04 GTO has a 4 link rear suspension, Anti roll bad and coil overs. Looking at the front it has been converted to front steer manual rack and has Coil overs. What is there available to improve the overall front suspension without going the high dollar stuff? Not looking to be a real track car but would like to go to a pro touring set-up in the near future.
