Re: Brass/copper vs plastic/aluminum radiator
Some places offer all-aluminum radiators at about 30-50% premium over plastic/aluminum...depending on how exotic your car is.
Aluminum is much lighter than copper/brass, but copper is the better heat conductor and dissipator...it's lower heat capacity allows the metal to rise in temperature faster, providing that needed temperature difference between the surface and the surrounding air.
All I'll suggest is that you make sure that the coolant used will protect it. Most new brand-name and and OEM formulas are made for aluminum.
