Spoon Rigid Collars NCP91

There is so much flex in the OE suspension, the subframe would be the last thing I would worry about. I also don't like the idea of lifting the body by placing a spacer between it and the subframe.

Interesting in the video... When they compare the two cars the blur on the "after" cars wheels seems to make it look like it was going faster when it hit the block, making the suspension instead of the chassis take the load - it would be easy to synch the videos in post production. Also the tire on the after car seem to deflect a lot more, another indicator of increased speed or lowered tire pressure.

Echo's don't have this collar, but Jason's right on point - the factory suspension has way more flex than any positive effect this would ever have...

True, but your'e dealing with two fairly independent systems. Like stated in the video, on race cars, these areas where the bolts are that connect the body to the subframe, these parts are actually welded. Its not really the suspension its working on but rather the connection of the engine, transmission and suspension to the subframe which is a rather lose and you can say primative connection on alot of non luxury or more expensive sports cars. The effect of play in the stock suspension is independent of of the effect of rigid collars since they are separate areas in a cars makeup. Thats like saying if you add a front upper strut bar, there would be no positive effect unless a rear strut bar were added as well.

Note: I have the UR front lower 4 point stress bar. Apparently, these are four of the bolts that connect the body to the subframe. The collars go in first and strut bar slaps on after.
