This is a rule change that should have come about long ago. A two row aluminum radiator can be bought for less than a four row copper/brass radiator, and will cool better.

A new radiator that cools better is good for the sport. Less chance of leaks, and a faster cool off time between rounds. The lower cost is icing on the cake.

By the way, the water is really where the weight is, and the difference in weight between copper and brass is not any real advantage as far as weight goes.

If you don't want one, don't buy one. It won't be the material that the radiator is made from that decides the race.

There are a couple of companies out there that offer a package deal on an aluminum radiator, an electric fan, a shroud, and a wiring harness complete with the relays. It's a big savings for a racer, on something that will make assembling their car and making it reliable a lot more simple.
