I didnt at any point say the heat would produce thrust and in any case even if it did it would only be proportional to the speed of the air so when braking the air flow slows.
it would only cause the car to have problems if there was a forced propulsion like a jet,
The aston martin v8 vantage was developed with the goal of being faster than the 911 it was endlessly tested on the nurburgring with that goal it has more power than the 911 and its a very very highly developed yet its still not as fast as the 911. Now i am not saying that the sole reason for that is having a rear radiator but i am sure it is a contributing factor, hot air is less dence so it changes the dynamics of the wake behind the car, drag coefficient is one of the most important aspects of a fast car so it stands to reason that if there is something causing less drag its going effect the cars speed.
i know you dont have to have a non conventunal rad but you need space to mount one and somewhere to suck the air in so from a design point of view its would be wiser to stray away from the slab stile radiator.
i dont think its a stupid idea having a radiator built into body pannels, you are thinking in the conventual sence of how a car is designed but if the car is actualy designed with that aspect in mind its not too hard to implament. it may not be the sole radiator on the car there could be small heater matrix size rads with vents from the rear wheels, vents reduce the air friction on the wheels anyway so again it would not be a bad idea. if engine pistons cylinder and heads where ceramic coated along with the exhaust manifold less heat would need to be removed from the block in the first place
as heat would not transmit as well through the metal components. That then cuts the thermal differential the components are subject to resulting in a much longer wearing engine and its is a very good way of getting the most energy you can from the detonation.
