Well lads looking for more feedback again. I want to refresh the cooling system on my 323i. I was toying with the idea of a alloy rad. Is it worth it ? Or should I just stick with OEM?
It currently has a viscous fan too but the clutch is fooked so I rather go electric altogether. All opinions welcome .

Also I want to go go down the road of a lightened flywheel and possibly lightened pulleys. Don't have much experience on them , if anyone has any feedback please do share.

Thanks , Adam
