I wanted to touch on some of @daves points.
Brembo Advantages -
Pedal feel will be better - The stock piston area of the stock caliper is 3.04 sq/in. The Brembo's have a total area of 4.37 sq/in and the Honda Wilwood has a total of 8.24 sq/in. Piston area determines the amount of force applied along with the amount of volume needed to move the pistons. The higher the piston area, the more volume needed to move them, but a higher force is applied. The Brembos are going to give a much more similar pedal travel to the stock setup compared to the ZZP. Both kits are fixed caliper setups that remove the slider pins and will give better pedal feel than stock anyway.
I'm not sure how he's justifying saying that the pedal feel will be better with brembo, while also saying it will feel similar to stock.... Stock pedal feel is absolute trash. Larger piston volume gives the driver much more leverage against the brakes, reducing the required pedal force for a given stopping force, while also making them easier to manipulate (more resolution). The pedal travel on our kit vs the stock brakes is nearly identical but it works a lot better. The stock master cylinder is more than capable of moving the larger pistons of the Wilwoods because the actual caliper volume is smaller than the Brembo or the Wilwood Aero 4 calipers. This is why we work directly with the manufacturer of the calipers to ensure you are getting the most bang for the buck and components that will greatly improve stopping power without having to break the bank.
Larger diameter rotors and thicker. That gives the Brembo kit much higher thermal capability than the smaller than stock ZZP rotors.
Technically correct, but this isn't very applicable in this context. Almost no one is running their slingshot on a road course with 20+ minute sessions. And IF someone was, the pad selection is the first factor in the heat handling capacity
Larger pad volume - The larger pad volume of the Brembo kit will absorb more energy and prevent thermal shocking the pad much better than a smaller brake pad and have longer lifespan.
Again, this is simply a matter of selecting the correct pads. SFWD (Sport Front Wheel Drive) Hondas that are going 200+mph use a lot of brake, it's not all in the chute. The chute is only helping for about the first 50mph and they have no issues with rotors/calipers that fit under 15" wheels.
Caliper designed for rotor diameter - The ZZP kit is using a caliper designed for 10.3" rotors, but is using just under stock size rotors (11.6"ish), which keeps the rotor from fitting correctly into the caliper. Not a huge deal, it will work, but the Brembo kit is designed for that size rotor and has correct caliper and brake pad fitment.
If it fits without hitting anything, it fits. When talking exclusively about calipers that have pistons on both sides and the pads ride on pins the caliper and rotor are both locked in position.
Center of force - Because the diameter of the rotor is larger on the Brembo, the center of force for the brake pad is located further from the center of the axle. The further out, the more mechanical advantage the brake system has on braking force.
Yes, being farther from center WITH ALL ELSE EQUAL will increase braking force. Using this as a talking point as a benefit while earlier acknowledging that honda wilwood caliper has nearly DOUBLE the contact. It is deliberately disingenuous to focus only on distance from center as a benefit.
One of the things we do for all of the supported platforms at ZZP that is different from a lot of companies, we make parts and upgrades that are tuned specifically to that market and application and for what the masses are doing with that vehicle. Doing this allows us to come to the market with different kits that are generally at lower price points and more cost effective while still immensely improving the performance of that vehicle. We aren't out there trying to convince our customers to spend more than necessary for their given goal. If you think back to 2016, before ZZP entered the market, the cost of everything was a lot higher than it is now. Companies were charging $5k+ for a stage 1 turbo kit. We came out with a kit for $3k that had the same performance numbers. The other companies ended up following suit with pricing. We've done this with several products in the Slingshot platform and will continue to do so.
