I fitted them because my subframes were off and the marketing blurb told me it would make me more attractive to woman.I couldn't say if they made any difference.....I go back to my earlier point, if the frames are off and you can afford them then fit them, they certainly won't make things worse.Mine were a really nice blue colour as well.

I had them fitted nearly 2 years ago on mine .
A mechanic friend of mine has actually shown me the scuffing that goes on between a subframe and the shell during use .
I've also read somewhere that subframe movement is why cars feel soft and worn out at higher mileages .
However , as I have my alignment done every 2 years or so I cannot say that having them fitted makes a difference .
But if your having your subframes off it makes sense to have them fitted !

Replace wot with OEM?

I was thinking of the wrong car - the S2000's subframes aren't rubber-bushed.
That's the only time you'll get movement and it's intentional.
I agree with Ray.

Lee, wind your neck in mate.but your right, if Ray doubts they work they probably don't.

And as for all that garish blue under your RED car....

ooooh seems this thread raised a few hairs!
The collars are not just to stop subframe movement. As DD said, correctly torqued bolts will hold them in place. Unless of course its an FN2, Octavia VRS or Audi B8 chassis to name a few. The FN2 even has a Honda service bulletin where they grease the mounting faces... no it doesn't fix the problem.
However an incorrectly aligned subframe can cause other issues like excessive vibrations, poor alignment, lack of alignment adjustment, excess road / chassis noise, scuttle shake...
Their purpose is not to only prevent movement but contribute towards a reduction or improvement in the above. We have fitted them to many cars where correct alignment could not be achieved until they were installed just as an example.

None of the mounting points on my subframe showed any sign of polish from movement and the bolts weren't particularly tight.
And the actual movement possible if you have all the bolts loose on say the rear subframe is minimal when the accumulative tolerance is added up between the holes and bolts . Loosen them all and try moving your subframe about , it will be very small, I know this because having made the decision not to get collars I thought I would try and centralise the movement , there was sod all to measure.
I know refitting my sub frames they had to be lined up pretty well to get the bolts to enter and start , the bolts are now very tight !
When having the Geo done my car turned out to be very straight and square although I know the rear subframe is skewed in relation to the body shell, I took a few measurements. I seem to remember the shell was made virtually by hand albeit on jigs, but not by robot so I am sure it's not as true as many more modern machine made shells.
I do agree with Ray totally.
