I just ordered Titan Motorsports sway bars today and Supra TT subframe mounts. I will let you guys know what I think of them soon. Any one who has them please chime in and let us know what setting you have front and rear at. Thanks.

 

OK, so what would everyone suggest for a SC300 with a 1ZJ swap T-61 single setup. I currently have TT struts and Tein Springs.

 

I set my Fronts to the Middle setting and the rears to the Outer setting. I have been told that putting the rears to the stiffer settings before getting used to the way the car handles, could cause you problems with control.
I like the above settings

As far as stock supra TT rear sway bars go

94-96 is 22mm
97-98 is 20mm

You can modify the supra rear bar by pressing the end flat and drilling two more holes.

Look at the Titan bars for example.

You can gain a marginal but noticeable gain in stiffness to the stock rear supra bars that way. As far as bang for the buck goes... it's tough to beat.

 

This photo shoes the Supra rear mount vs. the stock lexus one.
Not much difference except the tab that the sway bar bushing mounts to.

It seems, if someone wanted to be crafty, he could fabricate this metal tab and weld it onto his stock mount and avoid spending the money on new mounts. Supra Tab is made of 1/8" steel. Dimensions are below.

For others, the time would be much better suited to purchasing the Supra mounts from Toyota.

For reference the parts numbers for the Supra mounts are

LH - 52206-14030 cushion sub-***
RH - 52205-14040 cushion sub-***

 

I found this extraordinarily useful .pdf file that is a freakin bible for anyone looking at the oem Supra TT sway bar install. This is the only time I have ever seen pictures of the two bars side by side. It is very clear that its the direct shape of the TT bars that makes it stiffer. Also this fun fact, never seen it before: 'The SC front sway bar is hollowed out to provide more flex. The bends are less sharp than the Supra's attributing to the looseness."

And confirming something many of us know, but well put: "...the rear of the SC is a whole different setup...SC mounts to the trunk floor while the Supra utilizes a much more direct route across the rear subframe mounts. Because the bar does not zig-zag thru the rear of the car, it maintains dramatically less twist and therefore minimizes sway much more efficiently."

 

Hey Scoupe,

The Drill here, Drill now, pay less thing isn't suggesting we drill in the arctic national wildlife refuge near prudhoe bay, alaska is it?

Theres plenty more oil to be had in Texas, the gulf coast, and the middle east...

 

there is no point to having a solid sway bar. it will be just dead weight. if you pick up any 200 level mechanical engineering book that talks about torque and torsional twisting you will see that like 95% of the torque is applied on the outside of the bar. having a hollow sway bar is not a bad thing. it actually saves weight.

if a company is selling a solid sway bar and says that it will drastically improve body roll just due to it being solid they are lying. the diameter and material it is made of, as well as the shape as seen in sc vs. supra rear, has the biggest effects on the performance of the bar. not solid or hollow.

 

I just got my degree in engineering. It is the principle of torsion. When torque is applied to a point on the outside of a circle, the center of the circle(axis) which is in the same vertical plane where the torque is applied stays stationary (or nearly so) while the point where the torque is applied rotates around the axis.

**** thats not very clear but it's the best I've got off the top of my head.

Buy yeah once again Pavel is right!

 

Glad there are some engineers here to keep the theory straight. If I picked up a 200 level engineering book I'd have a pretty hard time figuring that part out. The reason I posted was to share a .pdf file that I found somewhere a long time ago that helped me put the bars in. If the solid verses hollow is true, we can all wonder wtf the Toyota engineers were thinking. Doubtfull anyone is going to saw one in-half to confirm.

If nothing else, its a great how to and does a good job showing the shape difference that has not been pictured anywhere else.

RE: ANWR, I'll post my reply in gas prices and you.... what are you doing about it? rather than highjack the thread to make a point. fwiw, I have an Econ and Fin degree but drank a hell of a lot of beer with my engineering buddies...

 

No doubt it's a great resource. Thanks for posting that up...

I followed your thread over to Gas Prices....
