We recently upgraded a pair of plastic and Aluminium radiators on a Van Diemen International race car for Guille Racing in Guernsey.
These were made all in Aluminium and had a super high efficiency core making them much more efficient (and tougher) than the stock item.
Here is one of the pair in position in the side pod of the car.

I just got an email from Greg guile, part of which said this:
“I was thinking whilst cleaning it, what a good investment the radiators were as they have been a fit and forget part of the car.
The car spent a fair bit of last year blasting round the circuits of France with many different drivers. I can say in complete honesty, they were one of the most reliable aspects of the car!”
