I was wondering if anyone knew the life expectancy of a alloy rad like a pace one for example. Im fed up of the standard "made up of wet toilet paper" rs radiators. Like my exhaust for example, full stainless, have not needed to replace any of it. In my old car it was at least one section of exhaust a year. I can only think an uprated rad would be better anyway, but, can anyone tell me if they last well for the extra cash? ta
