got you

I once parked on a side slope and had to open the hatch, when I went to close it it would not line up and closed with friction. I could not believe the flex in the frame to cause this, the two bars will help lots to stiffen the chassis.

Interesting, I've hade my car jacked up from the rear in one corner, and tried opening the doors and hatch to see if there was any flex and never had a problem. Everything worked perfect. I was impressed actually.

there's no way they stiffen the chassis, because both bars pivot with the body..

Well, with the rear strut bar you literally rendered the trunk useless.
Now with the upper brace, you can't carry any passengers at the rear.
Maybe, its time to just remove the rear seats and save some weight.

Perhaps you are turning your ride into a full-time track car?

Kaotic Lazagna · 10-30-2008, 12:29 AM

Too bad us sedan owners don't have anything like that, at least I'm not aware of anything for the rear other than a bottom sway bar.

reggaetonfreak · 10-30-2008, 01:23 AM

mmmm, let me think, so unless I a dont plan on doing anything in the back of my car for the rest of its life, (if you know what i mean), mmm, yeah, thats a negative, it would have a purpose if you do auto x, m just saying!

ROCKLAND TOYOTA · 10-30-2008, 10:19 AM

^^ its whatever, we'll let this ass paper think how he wants. it makes for good reading.....

*Astroman* · 10-30-2008, 10:53 AM

Yay, I knew they'd chime in! Where's Loren?

I know the "effect" that Rockland is trying to explain. After installing the TRD rear sway bar the ride was was more comfortable while the handling was better as well. Since I have not tried this brace I don't feel that I am qualified to judge it's effectiveness. Same goes to everyone else. It's like saying you know everything about a movie when you've only seen the trailer.

cleong · 10-30-2008, 12:55 PM

Rockland noticed a difference and he claimed that the car was smoother. If you have basic knowledge of suspension you'll find that it is counterintuitive that stiffening the chassis brings a smoother ride, because road vibration and shock are more clearly transmitted through a rigid chassis.

Unless, of course, that the chassis is so flexy that it flexes more than the suspension does. Bracing this flexy chassis would force the suspension to work.

Given our experience with the Yaris LB this would hardly be the case - to me, the monocoque is stiff enough as it is (but this is subjective). So it is unlikely that you actually gain a smoother ride with the body bracing.

I would love to hear any theory on how a stiffer chassis creates a smoother ride.

CASTREX · 10-30-2008, 01:33 PM

I like the bar.

Seems easy to install and remove and cheap enough to have it as an accesory for autox or track days only. When you are not carrying the rear seats anyways.

Agreed. This car has to be very stiff to begin with to make safety standards.

ROCKLAND TOYOTA · 10-30-2008, 03:14 PM

so for my lack of describing better the change i experienced we have this.

keep it going it makes for interesting read......

Thirty-Nine · 10-30-2008, 03:48 PM

Hey, if you like it that's all that matters.

It's a shame there's no way to really verify whether or not they do stiffen the chassis other than the ol' butt dyno ... er ... "butt skidpad." (Ewww?)

Bolt on braces, always guaranteed to start an argument.

(I prefer welded in ones myself.)

Yes, for all the money wasted on these stupid things, you could have a cage that actually does something significant.

*Astroman* · 10-30-2008, 11:10 PM

Or, you could stop wasting your time saying they don't work.
