Front no, rear kinda.
Simply a strut tower bar is designed for old school cars where the strut towers are located forward in the engine compartment vs. most unibody cars where they are directly mounted to the firewall. (The firewall is the most rigid part of the body, a cheap bar won't help anything) The "cool" thing in the tuner world is to get one and say it helps.
Pro tip: Go to ebay and get the cheapest one you can find. Put it on (if it fits), post in the appropriate thread complaining about Ebay parts in the GENERAL COMMUNITY, and enjoy your cheap bling.
