Are you looking at strut tower bars for the front? Rear? Or do you mean sway bars? Just want to be clear on what you mean.
Larger rear sway is a do.
There really isn't a strut tower bar for the rear.
Don't waste you time or money on one for the front. It won't do a thing. The front of the car is very very stiff, especially by the firewall where the A-pillars come down. Thats where the struts are and its one of the stiffest areas on the car. Even if you want it just for the bling factor, it is mostly hidden by the cowl so its a miss there too.
