Are the radiator and oil coolers mounted up front with plumbing running to the engine or is air flowed to the rear with aft cooling?
Front mount coolers could add a lot of weight with fluid lines and pumping.
Great question. It doesn’t seem to have been discussed. Those huge vents on each side of the car appear to argue for side mounted twin radiators. In looking at the galleries of the car at Chevy’s website, I can’t see anything definitive there, either. A complete schematic of the car would be helpful.

That's the only way to do proper cooling on a mid engine car. There's not enough space in the rear or clean air.
Also don't expect a dedicated air to oil cooler. Tadge said the oil cooler was 25% bigger which doesn't matter as the key factor is how much surface area the radiators have.

I think the setup really isn't too much different from the C7 ie engine radiators up front, trans and diff coolers in the side intakes. Standard mid engined stuff. Either way, should be much improved over the C7.
This is going to be a problem with rocks. Needs a smaller screen to protect those radiator fins. First thing I'll do is try and get some 1/4 inch hardware cloth in front of the radiator
Whatever weight that would be added by running coolant pipes to the front would be more than compensated for by deleting the driveshaft, torque tube, and the full-length exhaust that a front engined car requires.

I am not so sure there is much of a weight saving with at least 4 cooling pipes and pumping.
Also,if the oil cooler is front mounted how do you drain the oil lines on an oil change?
It's a liquid to liquid cooler like the C7. The oil doesn't leave the cooler brick adjacent to the engine. The coolant absorbs the heat of the oil and then flows through the normal cooling circuit.
If the water coolant radiators are not mounted in either side, like a race car, but instead are up front, then there is really no need for these gigantic side scoops. Smaller NACA ducts could’ve been used for the oil cooler, transmission cooler, diff cooler and any supplementary radiators of any kind. Kind of disappointed. I thought we might have two big side radiators with very short hoses and short runs. Of course, this may have required the trans and diff coolers to be in a rear grill and cramped the luggage space.

What? You're gonna add several nacaducts all over the place. Those are hideous.
For the z51 you need:
Engine air intake
3rd radiator
Transmission oil cooler
Differential oil cooler
2x rear brake cooling ducts
