now that summer is approaching, trying to make every effort for the car to stay cool on occasional trackdays. any suggestions on which fan to get as a replacement for stock?

 

IIRC I've always read that the stock fans are quite adequate as far as air flow is concerned. However, when they break, the cost to replace them may not be conducive to keeping them.

I still use stock and on the occasional track day, they seem to do a well enough job, however, that's not to say that I don't have some heat issues. But I think that has nothing to do with the fans per se, rather the setup as a whole.

Of course, YMMV.
