You don't need a front sway bar. FWD cars have slight understeer. By getting a front and rear sway bar, you'll keep the understeer. If you just get the rear, it'll bring your car more into a neutral steer. Most people get only the rear sway bar...I think people only get the front sway bar if they track or autocross their car.

Front strut bar is quite noticeable in the beginning. Afterwards, I either got used to it or the bar as been worn in a little (on my accord, it was so hard to put it on...after a few months, I was able to remove and put it on super easily).

My accord has neuspeed front strut bar with ST rear sway bar.
My TSX has neuspeed front strut bar with Comptech rear sway bar.

Both of my cars work great for how I drive
