strut bars

Would strut bars in the front and sway bars in the back really help my car in autocross?

yea it would do ya a little difference reduce body flex and body roll

It will help the handling when you make quick turns!!!

Improved handling.

if your not looking for a large amount of increased oversteer, upgrade both sways instead of just the rear. also, solid subframe collars such as SPL (www.splparts.com) or Greg Dupree's will make as big of a difference as strut bars and watnot if your big into tracking your car....
