Increase the diameter of your brake rotors: Every inch of rotor diameter increases the brakes leverage to stop the vehicle. Many models of car/truck have larger brake discs available for sporting models. For some more pedestrian models look to bigger cars/trucks from the same manufacture.
Although different diameters of brake rotors are sometimes available as a high performance option, these rotors also require different calipers, so the swap is not trivial. Also, the standard size of wheel may not fit over the larger brakes, so a wheel diameter change may be required as well.

Realistically, only a few percent larger diameter is likely to be available without radical mechanical changes, but even that difference can be worthwhile.

Vent Brakes: Venting brakes is a trick used by street rodders to increase braking capacity. Drilling holes in surface areas of Drums/Rotors where Pads/Shoes contact. This allows the gasses and pressures of brake dust and heat to easilly escape the mating surfaces, increasing the contact area thus better braking performance.
In racing conditions, this is valid. In street conditions - especially the way an EV is typically driven - this is a complete non-issue. The holes solve a problem which does not exist, which is why production cars rarely include this feature... and when they do, it is to visually impress buyers, rather than to stop the car.

Also, has anyone ever actually drilled a drum surface? That seems ridiculous; the rational alternative is to change from the century-old drum design to modern disk brakes.
