Lightest KZ radiator

So I’m looking to shave some weight off the kart in my bid to get back down to the light shifter class around here. I currently use the AF gold large radiator, which is very nice but I’ve heard it’s heavy. Looking for some insight if anyone has some as to a lighter option suitable for KZ.

Just take the water out of it. It’ll save a decent couple of pounds. Lol I’m just kidding.

@SahibT beat me to it… An empty one. :slight_smile:

I’ve been trying to find out about this as well. Newline has an RS that may work, looks to be around 4lbs without mount. Sure would be helpful to have weight info with mounts provided.

'92-2000 Honda Civic radiator. Plastic end tanks, aluminum core. Weighs half as much as an all-aluminum piece.

Mounting on a kart is… interesting.
