The short answer is
Struts (no spring changes)
Front Sway Bar
Drop in Air Cleaner
Tires
Brake Pads

That's about it.

Also,
lighter wheels (same exact size & within certain offset)
catback exhaust
alignment
brake fluid

Thanks, knew I forgot something. Not sure how light the stock STI Forged wheels are, but they probably aren't that heavy...

The STi BBS are *great* wheels for AutoX... very light... I'd guess in the 15 lb range, which for a 17"x7.5" is very light!

And let me reitterate one of the items on Dean's list: tires! The RE070's are great tires, but if you're going to run in A-Stock (and not in NAS, aka Street Tire A-Stock) a set of R-compound tires will likely shave 2 second off a 60 second course! Tires are *the biggest* mod you can do next to seat time.

Thank you guys, race tire is great but not for the budget now.

Then you definitely want to run in NAS with Matt... We can help you with tire pressures etc. when you come out. Look foir us...
