Ksport is proud to announce our newest addition to our SuperComp brake kit line up, the 421mm aka “Big Daddy”, which is the nickname it’s been given in our office. This behemoth of a brake kit measures in at 16.6″ which is larger than the entire rim of many econobox vehicles. This system offers massive stopping power thanks to our SuperComp 8 pot calipers. For those that aren’t aware, there is a huge difference in calipers when you jump into our SuperComp line up. These calipers are so ginormous that they require 4 brake pads per caliper. Just like our 380mm and 400mm kits, the 421mm kit comes standard with two piece floating rotors. Oversized differential bore pistons help provide insane clamping force, all while still utilizing your OEM master cylinder and ABS system. Kits also include stainless steel braided D.O.T. approved brakelines, caliper brackets, brake pads and hardware for a bolt-on installation. If you want to roll like a Boss, make sure your vehicle has 21″ wheels in order to clear these bad boys. For more info give us a call at 480.829.8100 or shoot us an email to email@example.com.
