Time for a cooling system refresh - OEM radiator still the way to go?

[0-60motorsports]

I have an NRF along with new Genuine everything else and my car gets hot on track. I'm probably going to try something else soon enough and move on from the NRF. Maybe a Koyo, maybe a do88.

I was going to order the Do88 yesterday but then i noticed its a triple pass like the CSF and i just dont want to face the headache of the bleeding procedure etc. At this time I would LOVE to buy the KOYO only if someone is willing to provide me dimensions and weight of the box and ship it to my forwarder.

im coming due for a cooling system refresh. everything is still intact but its now 20 years old.

I cant find a list of hoses that need to be refreshed and I havent done the m3 before. Obviously the expansion tank, the hose to the expansion tank up top, maybe the bottom one and the two radiator hoses and the radiator. My waterpump and thermostat are fine.

What hoses should I make sure I get?
