Speed is useless unless you can slow down from that speed. To help the Hellcat stop, Dodge has employed massive Brembo-branded brakes. Up front, they have 15.4″ two-piece rotors with six piston callipers. Not only will the dissipate heat quickly, improving longevity, but we’re pretty sure they’re powerful enough to stop the rotation of the earth.
The only way to get that large of brakes to fit on a car is to have 20″ wheels. The tires are all-season units from Pirelli that also work well at high speeds. Our recommendation would be to buy the summer-only tires and get a set of winter tires if you must.
