If someone has a force gauge and one of the strut bars, go make use of the two, rig up something and drive around, see what kind of numbers (if any) are present

but they did weld a bar from the strut tower to the firewall, unless thats part of the rollcage?

i took mine off and didnt notice any difference *shrug*

That is part of the roll cage ;)
also note on the left hand side of the picture. the brake brace also (rusted).

It is a full group A Turbo supra :)

Hell even the BMW folks that race in Cup car series don't bother as it is literally worthless to them as they run a full cage anyway :)

See this short thread where 2 well respected Supra Guru's (Larry-A and IJ) almost went at it:biglaugh:. They had different opinions about Strut bars. Larry-A did make a good point POST 25, but he never got around to proving it or didn't care to. But he did explain why he thought that strut bars did make a difference to a certain extent. (I'll hide my signature in this thread so you guys don't see my strut bar, LOL)

EDIT IJ just posted before me:icon_bigg

Our Supramania suspension expert Wiisass should give his 2 cents as well :evil2:

Take a look how they did the race cars ;)
(not a placebo bar in sight)

EDIT: bah, I type slow and was beat to that point like 4 times, lol.

An STB is a good place to hang your shop rags and rest your arm when you are changing your plugs though. ;)

bah we all own supras we can afford one.. err... :biglaugh:


well strain guage is part of the equation.

Then you need something to capture the voltage relative to the force being imparted on the strain guage. Like a Pectel, MoTeC, Bosch Motronic etc :)

I place a lot of stock in Larry's opinion and if he'd been able to provide some evidence to support his stance I'd have made up a bar to test/develop.
(as always I have my idea of the form it "should" take so it would actually do something when installed)

Someone should test this. I used to have them and maybe it was just in my head but I used to play around in the miller stadium parking lot ( Where they do autocrossing ) before and after I got them.. and I could swear I felt a difference. I'm sure its easy to trick yourself though...

Who's up to the task? :).

It's just basic geometry.

Take a cardboard box with the ends open and flex it it's a big wobbly mess even though it's got 4 sides (this roughly replicates the front subframe/shock towers and Placebo Bar)

If you triangulate the corners it'll become more ridgid and resist the flexing.

i understand what your saying, but it has been proven on the mk2. using a cusco pos bar driving wit hthe hood off it was shown to flex, alot. thats why the ljm bar was designed and then tested on the same exact car. it didnt appear to flex at all around the same corners. no other changes. i think the bars design has alot to do with it so cant just say any strut bar is a good strut bar.

I mean, I wasn't like, oh man night and day... far from it. If anything it was barely noticeable ( same with the hatch bar )... but I coulda sworn I felt SOMETHING. Who knows, that was like 4 years ago lol.

William: My posts concern the Mk3 chassis sorry if people missunderstood and think I mean ALL Stb's.

yeah, you guys have a double wishbone suspension the mk2 doesnt have. but even on the mk2, not all stb work.

heres some pics of the ljm bar for the mk2. these pics are not my car btw.

i know this. the point of my post is that some strut bars work while others dont. this has been proven on the mk2 and could likely be proven on the mk3 as well.
