My point is that the ZL1 needs bigger brakes to dissipate heat because of it's weight and not it's horsepower. The stopping distance of the ZL1 from 135mph is the same regardless of how much horsepower it has. You may be able to improve this from stock with pads but you will still only be able to brake at the adhesion limits of the tires. You're imaginary straight scenario aside, corner after corner you are hauling down more weight in a ZL1 than a 1LE. Lets take a short track where the HP of the ZL1 is negated. The brakes will still run hotter than the 1LE on the same track. Weight. I'm not saying your mathematical formula is incorrect. I'm saying that regardless of how much HP the Z has or how fast it's going it's heavy so it's making more heat in every single braking event. Even if you pulled 250hp from it and kept the weight the same it would still benefit from the bigger brakes. Ask me how I know heavy cars cook brakes faster regardless of speed.......

Um it is both, the car is heavier... yep needs more brakes. The car has more HP and thus has higher interval speeds between turns so it has more energy to dissipate pre-turn. Hp leads to higher acceleration which leads to more need to decelerate into the turn. Gut feeling and we could start working on the actual heat load, but gut feeling the 200 lbs more or 5% of race weight is probably less than the higher interval between speeds that the ZL1 will attain but is more tack dependent.... So lets call it equal. Meaning the brakes need to be 10% larger (in total heat dissipation). Off the napkin.

wow literally saying his feelings trump physics.... ZL1 power to weight ratio is greater than the 1LE.... therefore... it will reach higher max speeds before the start of braking.... since the LAWS OF PHYSICS [ (Kinetic Energy = 1/2 (mass) * (velocity)^2 ] were still in effect last time I checked... the speed have an exponentially greater effect on force than mass.... so yeah your wrong.

More HP = more brakes because science. Got it

Here's an interesting point to dig up this old argument...
A Loaded 18-wheeler trailer stops in a shorter distance or longer distance? This is an actual question on the DOT CDL test, and the answer might surprise you. The braking differences on a ZLE vs 1LE and the necessary larger brakes on the ZLE are because the frequency of higher rates of speed, per corner and the ability to shed that heat energy are far greater. Weight adds to the capability to keep the tire planted which is also why the suspension plays a vital role. Ah, but the previous comments never took into consideration the two clutches in the A10 transmission which are also playing a huge role as well as the E-LSD in maintaining the grip while at or near threshold braking.
