My Ultra Racing rear sway bar install

Well I finally got my rear sway bar from MicroImage (Thanks Garm!) I installed it the same day and heres the pics...

Before install

Note that the sway bar is sitting on the ground facing the opposite way from when it is installed


Back wheels off ready to remove the nuts

Also note the jack under the shock to relieve the pressure so i could pull the bolt back far enough to put the bar on

Right side installed


Finished!


This rear sway bar is really great! The car is a lot less nervous in corners. The back end used to tend to step out on hard turns, especially when hitting bumps. I had to learn not to adjust so much for that behavior. When taking the highway on ramp near my house, I'd take it a little shallow because the back would step out a little on the bumps, well first time or two, I took it almost too shallow! I'm used to it now, and the back end tracks very well, now. I'm very happy with my purchase!

I just installed mine today..My funny story: 19mm Sway Bar Install

Well I kinda confirmed the fact that this part CAN be installed without either jacking up the car, nor removing the tires. Why I did this, I wanted to prove what someone had said previously, and I really didnt feel like searching for the jack arm for my floor jack.

Anyway, all went well, Sway bar installed, and I LOVE IT!
Car feels totally crisp, allowing me to push the corner that little extra bit, or just allow the car to transition a bit smoother throughout the corner. I cant wait to get this baby to the track and start to mingle with the other cars.

^ agreed. I installed my TRD late last week and it was cake. I didn't jack the car up, didn't remove the tires. Just bolted it right on.

And yes, everyone should get a rear sway, even people who don't care about handling. It makes the car that much better.

Don't like to do this, but the way you're describing this is incorrect, and misinformation spreads like wildfire on the internet, so...

If anything, adding or increasing the size of a rear swaybar (or otherwise increasing rear roll stiffness in any way) will tend to make the back end of the car "step out" (oversteer) more in a turn, not less. Remember, a rear swaybar is transferring weight from the outside rear tire to the inside front, it's giving you LESS grip in the rear... but that's generally not a problem in a FWD car.

Perhaps you're referring to body roll? The car will certainly roll a lot less with more rear roll stiffness, and as you said, it will feel a lot more planted.

BTW, Garm sells two different Ultra Racing bars, a 19mm and a 23mm. Which one is this?

Would it be incorrect if I stated that when it rains or theres alot of water on the road, I FEEL it even that I have to drive slower around bends on the freeway and such because it FEELS like the rear is going to kick out, as compared to when not having the rear sway bar?

I like the installation pics and description of the poster!

That is a better description. Without the bar, you FEEL like the rear is going to kick out because of all the body roll back there.

But, in reality, the back end is ACTUALLY more likely to kick out with the rear bar in place. That's an important thing to be aware of. It's one of the downsides of big swaybars. They increase confidence by reducing body roll and making the car FEEL better... but, at the limit, they often have effects that the driver doesn't realize... until it's too late. They make the car less forgiving to big driver errors.

Find a safe place to push the limits of your car and learn what it's going to do! (even if your car is completely stock)

That is what I was reffering to Loren, that since Ive had my bar installed...it FEELS like the rear is more apt to kick out while going around bends on the freeway during wet and rainy weather. Almost like you can feel it getting to a threshold and you know you have to lay off the speed a little bit or it's gonna come on out on the bends, even though your not really flying or going all that fast down the expressway.

YES! Now you're talking sense. You really ARE at the cusp of losing the back end when you push it on those wet sweeping turns. Slowing down there is good... but... don't abruptly lift off the gas, and don't even think about touching the brake in that situation. Shift too much weight forward off of the rear tires that are already barely gripping and around you go!

I'm used to winter driving, the ice and snow, etc so I've learned the best thing to not hit the brakes or anything else, just lay off the accelerator and let it coast down on it's own instead of trying to make it stop.

By the way, love that BRG car of yours!

I think he means he used to specifically push it into understeer on the on-ramp, and would aim 'too shallow' to compensate. He has enough grip now the car's going where he aimed, which was still 'too shallow' which was now a problem.

Well funny enough when I ordered a month and 1/2 ago only the 19mm was available so that's what I got. As far as the whole stepping out issue, I am big proponent of preventing misinformation, so I understand why you posted this. I'm not sure how a rear sway bar transfers weight to the inside front wheel, but I'm just saying how it feels to me. The back end used to hop around every time there was a bump or dip in the pavement. The back end has calmed down, now that I have my sway bar on. Maybe I'm wrong and maybe I haven't pushed it enough to tell the true difference before and after. It seems to me, that it transfers force from the outside rear wheel to the inside rear wheel, allowing less body roll and keeping both rear wheels more firmly planted.

Now I'm not an expert, nor do I claim to be, so I would like to know if/how I'm wrong. I'm not too proud to believe I'm always right, so please let me know if I am in error.

Read the thread I started about the 23mm bar, especially the first post. It has a pretty good explanation of how the rear bar works. It is admittedly counter-intuitive if you're not well-versed in the black art of suspension tuning.
