Yes it's another one of those I saw it on Ebay threads
yea so I so this on ebay...and i'm scratching my head right now, think I'm pretty sure they doesn't do anything for the car
http://cgi.ebay.com/ebaymotors/ULTRA...item2a13e1dd70 but go ahead and correct me if I'm wrong |
Well i'd say the animations pretty well describe what they do... Although it may not be noticable to the average driver, the chassis does flex quite a bit when you corner even with low G-loads. this does help with the overall comfort factor, but track-prepped cars don't really need this comfort, so adding the bars to improve the overall chassis stiffness is a good idea.
Why? Mainly because it will reduce flex in the shock towers and subframe (thus decreasing wear on the overall system and it will keep the wheels more planted while cornering and the coilovers/struts more even, improving the cornering even further). |
They might be a good alternative to solid subframe mounts for a street driven car. Although I seriously doubt any major change in the car's handling characteristics will occur. A better investment would be a set of urethane suspension bushings imo.
|
I could make those braces for a fraction of that cost before they could process the order. And have the warm fuzzy feeling of not having ebay parts on my car.
|
it's idiocracy in action.
the rear subframe is meant to move freely, placing them on a vehicle without solid subframe mounts will rip gaping holes in the frame rails. even the motion of a fraction of an inch with the stock bushings, something is going to give with how cheesily they mounted them. |

Oh man, this is classy. What moron "engineered" this? Those rails barely support the mud wasps that live inside them, the first corner you take that brace will be torn out and flopping around.

The bottom line is that if you want that cross-member not to move, you're going to replace all the rubber on it with delrin or aluminum. |
And notice they take up the stock exhaust hanger holes as well. You can even see in the picture how the exhaust mount is hanging to the side. :D I love how the driver side will tear through the frame rail and end up in the fuel/brake lines.

What an awful, awful, terrible idea... People actually buy this garbage???
|
oh man, I wish I could see the face of the first kid to buy this after test driving his car, then stopping to see what that "rattle" he developed was.

Actually that sort of compliance will not really become enough to alter suspension geometry greatly, in fact the difference between a stitch welded chassis with a roll cage and a the same shell unmodified wouldn't be that noticeable to even a highly-trained race driver until that car has race-compound tires on it, street compounds don't add the same magnitude of forces into the chassis.
The shock towers are nothing more than a two-force member, they pivot if the subframe moves forward under acceleration, or sideways during cornering the only forces they are seeing are along their length in compression. The bottom line is that if you want that cross-member not to move, you're going to replace all the rubber on it with delrin or aluminum. |
but their diagram shows it coupled with an upper strut brace, which of course will make a noticable difference.

is this some kind of cheap knock off from the autoexe braces??
What weird mounting positions lol |
