Change the front sway bar. A lot of the track guys (I think) choose Hotchkis. Maybe also try removing the rear sway bar - not sure if both are an option for your class. Testing out a few different configurations on your car would be ideal.

Based on my research, Koni Yellows are probably your best bet for shocks. Others with specific experience will be able to provide much more insight (I'm still on OEM shocks). You might even be able to find a well priced street used set in good condition on this forum or via other avenues.
