for a classic, any real gain in fitting them ?

says goes from 2kgs of standard down to 440 grammes for this one, a nightmare job waiting to happen just for no gain or worth doing ?

Ive fitted one purely for show and as the engine is already out it was no drama. i dont think there is any gain to be had but at a competive level combined with lighter flywheel etc then every little helps.

The one u listed is smaller then oe , If you are to get one I would get one of the same size and from a reputable company too as a poorly balanced unit could have a negative effect on the engine.

I fitted one years ago on the sti, with no issue,
Any rotating mass you remove has to help the engine rev more freely.

Or at least read up on why quality damped pulleys are a good idea.
Take a look at this discussion https://www.scoobynet.com/scoobynet-...th-having.html

I'd like to got an ati one but st like £250 it's a no no

I've not heard bad stories about the cheap pulleys, granted they may not offer full benefit of light pulleys but at more than half a weight saving they should be better than stock ?
