Anti-sway bars go by many names. Sometimes they are referred to as anti-roll bars, roll bars, or sway bars…but they all do the same exact thing: tie the left and right suspension together so that the car corners flatter.

The sway bar is basically a spring that mounts to the left and right suspension somewhere, then is secured to a solid part of the chassis. It works like a torsion bar, by twisting. Naturally, a larger bar is going to be harder to twist so it is desirable to upgrade the sway bar from stock size to improve handling.

The rear sway bar is the most commonly upgraded suspension part in a front-wheel-drive car, following shocks and springs. The rear sway bar helps make up for FF cars’ tendency to push, or understeer, into corners. Upgrading the rear sway bar noticeably improves handling on most cars without compromising ride quality. This part is easily the most bang for the buck you are going to get out of your Acura/Honda suspension.

We have felt that the stock 2009 TSX suspension is indeed very well set up, and the chassis is noticeably more rigid than the outgoing model. And while it feels balanced through turns there is a distinct feeling that the rear end is just following what the front of the car is doing. With the addition of a larger rear sway bar, the car feels flatter and more confident than before in turns. The rear seems to help “steer” the car around turns better. This is not the same experience we’ve had in the past, where a rear sway bar will “fix” a front-wheel drive car’s tendencies. Instead, this bar helps make an already nimble and balanced chassis feel even better!

The drill bit you’ll need for the next step is a 13/32″, or 10mm. We figure a 7/16″ bit should work just fine as well!

Here’s the point at which some people say “oh, I have to drill? I don’t want to do that for [insert lame reason here]. Is there a bar that doesn’t require drilling?” Yes, there are some. They are either too small to make much difference or will cause the bracket to tear off.

Don’t puss out; buy the bar and drill the hole! I can always tell a poser when they don’t want to open a hole up 2mm for the fear of making a permanent, irreversible change to their car. The reward is in the improved function of the car. Enjoy running laps around lesser TSXs!
