Reasons to buy a strut tower brace:
1. You already have wheels, tires, springs/struts or coilovers, sway bars, etc, etc, etc...and are just looking for something else to throw on the car.
2. The last import you modded was in the early '90 and you think this is your only suspension mod option.
If this is one of your first mods go with a front sway bar instead...it will make a bigger difference. If you just want some eye candy spend your money how you want!
