Introduces this new twin 38mm Twister disk brake.This uniquely twin 304 stainless steel brake system contains:-Two 12 cooling slot 304 stainless steel rotor. Two big footprint Aramid Fibers layers 304 Stainless steel caliper.One high temperature high strength alloys center caliper.With it??s over size rotor and big footprint caliper the twin Twisters out performance any disk brake for the HPI Savage currently on the market today. The big footprint caliper using laminated fusion there will be NO gluing the Aramid Fibers pad to the Metal caliper.? High heat transfer big rotor with cooling slot run much cooler.? High friction coefficients by contact area and material enhance stopping power.? High metal strength preventing distortion and breakage? No gluing the Pads to the Metal calipers.? Reduced heat means increased life of all brake system components.
