Funny I was searching threads and happened to come across this... Anyway that was me! Was a good day, haven't been back to Sonoma Raceway since because of the weather, but plan on going back up when it clears up!

the only two power-producing mods left are aftermarket midpipes and headers.

outside of those two, and short of forced induction or nitrious, you're maxed out as far as making more power.

if you haven't done so, here's a few more ideas if you're serious about going quicker:

- run w/ a 1/4 tank or less, depending on how many runs you plan on making
- empty the trunk
- remove all engine panel covers
- remove the passenger seat and rear seats - they actually weigh a lot, believe it or not
- stickier tires in the rear
- soften up dampening rate, if you have coilovers: to prevent wheel-hop during weight transfer (when launching off the line).

You can change your FD gear ratio to make better use of the power.
