AZRR CYM FD Build Coming Together

I agree with Cosmo. I cut a bunch of small squares into my stock undertray and noticed a difference in temps both on track but particularly in stop/go traffic.

In stop/go traffic, the vents in the undertray it resulted in a small difference in cooling temps (~1 degree C) but a slightly bigger difference in air temps and related to heat soak.

Also, I recommend using some of these hose clamps on the silicon coolant hoses:

I had tried using some expensive, high quality, worm type hose clamps and they would loosen over a few heat cycles. These Breeze constant torque clamps work incredibly well and never loosen up.
