I recently dropped my 2016 Focus ST on H&R lowering springs. I was very surprised how.much better they made the car handle. I knew I wanted to upgrade the rear sway bar as well. I went with the Eibach rear sway bar for several reasons. Well known and popular name brand....CHECK. Well made quality product...CHECK. Two adjustment settings...CHECK. Affordable price...CHECK. Lastly, the red matched the Race Red paint on my car. Installation was not that bad. I opted for the stiffer of the settings right off the bat. I paired this bar with the Damond Motorsports adjustable endlinks. I was blown away how much better the car now handles. It stiffened up the rear end of the car tremendously and I can now carve turns like I am on rails.
I HIGHLY recommend this product!!
