ZZP Sonic Rear Sway Bar

Suspension & Brakes - ZZP Sonic Rear Sway Bar

Once you add some basic handling mods such as lowering springs, upgraded struts, better tires, etc, it becomes increasingly important to consider upgrading your sway bars. As you improve the ability of your car to stick to the road, you will notice an increase in body roll (or sway/lean). This is where a stiffer/larger sway bar setup becomes beneficial. Sway bars work by distributing the upward/downward force of the car evenly from left to right, in an attempt to keep the car level (eliminate the heavy lean, or body roll while turning) the factory sway bars are sufficient for a factory suspension/tire setup, but once you change things out, they are no longer enough. This is where the larger diameter/stiffer sway bars come in, they will help keep all 4 tires planted firmly on the pavement, and drastically improve your cars handling ability.

Sway bar 101: This is assuming you have a properly setup front/rear spring rate and good shocks/struts...  For example, lets say you are coming into a corner fast and want to make the turn.  If the car tends to understeer (front pushes/does not turn) you will want to increase the rear sway bar stiffness.  People generally prefer oversteer (rear swings out) in a corner in a front wheel drive car because you can always accelerate out to control the amount of oversteer.  If the car oversteers a lot, then increase the front sway bar.

Made from .120 wall 1" 4130 chrome moly, it is light and strong. The ZZP sway bar will transform your every day driver into a vehicle worthy of a road course.

Comes complete with bolts and instructions.

This will fit the hatchback and sedan models.

Tighter turns for real

What a game changer! Car is so much better around the turns. Only issue i ran Into was the bar/weld on the driver side was close to where the middle bolt goes on. Took some finagling but got it on. Would have been easier with a washer and nut vs the one provided.

Helps Out The Rear End Considerably

Another well built and solid product from ZZP. I've noticed its helped keep the rear wheels on the ground and feel more planted. To the people fighting about whether it does anything since the rear uses a torsion bar, I'm in the camp of it doing something. It adds rigidity right under the springs! Get this product with the lowering springs if you can, as the install requires you to remove the rear springs.

Sonic rear sway bar

FF-LSD alone was not enough, but the movement of the rear seems to have improved.
