Is there really any performance value to upgrading my radiator??? I found a performance radiator in a junkyard for $50, but I'm wondering if it's worth upgrading it or if I should just save my money....

I assume that a performance radiator would be much lighter and would keep up with my vehicle once it's totally modded out, but I never really thought about what the radiator really does and why it would need to be upgraded, I just always upgraded it before adding on Turbo/Super...

I have it on hold right now, so help me out! I'm not sure if I want it or not, so give me reasons why or why not.
