What do they do?

Totally centralises the subframes and eliminates all movement where the bolts go. Means when geometry is done it's 100% accurate.

there was a garage near me that was producing them for all Hondas

Never heard of them before. Why aren't these standard if they're that effective? Wouldn't cost that much at all to produce in masses.

Increased NVH, not friendly for a road car. Normal subframe bushes (not checked these specifically on a prelude btw) have rubber in them to damp.

The way that other guy was going he suggested there was less vibration and road noise. Those placebo pills are pretty powerful mind

These would have no benefit on a lude, which has no rubber mounting bushes and has locating pins to stop and lateral movement anyway.

there are no bushes and no locating pins on the subframes either if i remember rightly the bolts just go right through the holes in the subframe into the chassis the collars just leave no room for movement in the bolt or subframe the fact you can fit them in means there is an allowance for movement

Here are the pins.....

The tolerance on the bolt holes in the frame is tight enough that if you paint the bolts, you'll struggle to fit them. I don't think subframe movement is an issue on a prelude at all.
