strut tower bars are a noticable upgrade for the price, especially in cars that will see a lot of autocross and circuit driving. it will make inputs feel more immediate and percise since there is less flex in the chasis. some bars are definately more show than function so its up to the buyer to do the proper reaserch to see which ones are best.

i use to own a crx with skunk2 sleeve overs with 6/8kg front/rear springs and kyb agx shocks, and an ebay "skunk2" strut bar. with this setup and falken azenis tires i was able to keep up with my buddys mini cooper in the turns out where we drive. considering i got this setup for less than 600 bucks its a great bang for your buck upgrade. but as was stated if you go with sleeve overs make sure you get good aftermarket adjustable shocks, so you can setup the suspension according to what youre using your car for, and to minimize the bouncy nature of stiffer spring rates with appropriate dampner strength.

if your going to pick some up id go with ground control sleeve overs instead of skunk2 due to the fact that you call them up and order custom spring rates for your setup. also they have a lifetime warantee on their products even under racing conditions.
