Hi everyone,

My car is making around 450 whp now and I was wondering is there is any coolant upgrades for the M2 . Normally my car temperature (water) is 106C the stock thermostat are opening too late . So are the aftermarket thermostat, radiator or any cooling mods ?!

Maybe not for the M2, but we see plenty of high HP cars with tons of power over stock not needing upgraded thermos or coolants. However, on my 85 635csi i have an upgraded radiator and run Evans water-less coolant to keep temps down in case i get stuck in traffic on a hot day. i know this info probably doesn't help but maybe replacing the thermostat with (after a quick search) mishimoto low temp one which opens at 74 degrees would be worth a shot since they aren't too expensive. if that doesn't help run an upgraded coolant like Evans.

Add some water wetter and call it a day. Ran it in my E30 making 625whp. I highly doubt you really need it honestly.

Yeah . Just ordered Mishimoto thermostat and I think they will work well I well keep you updated . Also , Motorsport24de they have a new cooling system and they are experts in tracking and pushing the limits
