The look what I bought thread
Just pulled the trigger on these (UR idler and alternator pulleys) from over on my350z. My OEM ones are chromed but these look a lot sexier...hehe. I'll re-polish them or have them chromed. They are stock sized, the only underdrive pulley in the UR set is the crank pulley.

^^^ Marcus, dont chrome them - even though its not under-driven (stock size), its still light-weight which helps rotational mass... no point in defeating that by adding chrome. Just polish it out 
Caveat; in the whole of things it might not be a real noticeable difference, especially if its decorative chrome plating (which is much thinner and lighter than actual hard chrome) - but still, when someone looks at a lightweight pulley which weight added to it, they may think it's a defeated mod).
The other thing to consider is the pulley is a moving part and more subject to chipping (decorate chrome plating) - stationary parts aren't really an issue (so long as they don't constantly get banged with a wrench)... if it's hard chromium plating, it will hols up, but that's added weight.
So either way, polishing makes more sense (imo)... then again, show judges dont usually consider the things that I do

I don't know the answer to that specifically but I do know that my rims are triple chrome plated and they weigh 22# F and 24# R or 3# more each than the coupe 19's. My guess is that chrome may not be as heavy as people think, but I could be wrong. Wouldn't be the first time. 
Would most people notice? probably not... but a light-weight pulley dosnt give a ton of gains anyway... however, if you're gonna have a lightweight pulley, there's no point in gaining weight to it (he might as well keep his polished OEM in that case).
hahahahahaha more to come, more to come!
windshield wiper fluid marcus!
thanks man!

Went to the garage early today to put these on:
And they're too thick fml. But Summit Racing is awesome and they sent me a RMA to ship these back at no cost to me and they will replace them with the correct pads.

depends on if it's decorative chrome or hard chrome plating... I'm sure hard chrome will weigh more (much thicker). Both are gonna weight more than no plating of course... how much more? I dont know - but why add weight to a light-weight pulley?

My way of thinking is: if it doesn't make much gains anyway, why not go ahead and plate it, it's not that much weight, still lighter than stock, and chrome will almost always be less upkeep and look better than polished.
