ABOUT GIRODISC
Girodisc has earned a distinct reputation in the performance braking world for transforming how enthusiasts think about rotors. Since 2003, they’ve focused exclusively on designing and manufacturing precision two-piece, fully floating rotors that outperform traditional one-piece designs in both street and track applications. Their engineering approach reduces unsprung weight, improves heat dissipation, and maintains consistent performance under extreme conditions — allowing drivers to maximize the capability of their existing brake systems without the complexity or cost of a full big-brake kit.
Headquartered in Bellingham, Washington, Girodisc handles every aspect of design, machining, and assembly in-house using U.S.-sourced materials and advanced CNC processes. Their attention to detail extends beyond performance — the company emphasizes sustainability through efficient manufacturing, material recycling, and a 75kW solar array that powers their 17,000-square-foot facility. Girodisc’s commitment to quality, professionalism, and long-term relationships is evident in every rotor they produce.
The Girodisc system is a direct replacement for the OE disc, no modifications are necessary. The disc will bolt directly to the car and work with OE calipers perfectly. By upgrading your brakes with lightweight high performance replacements as opposed to a big brake kit, your factory bias is maintained as well as your ABS efficiency.
ABOUT THE ROTOR
When I recommend Girodisc rotors, it’s because they’ve earned their reputation through engineering, not marketing. Factory rotors on most performance cars weigh just over 32.5 pounds, but Girodisc brings that down to about 28 pounds per rotor — roughly a four-pound savings per corner. That weight reduction translates directly into better handling, faster response, and improved braking feel.
Their 72-vane curved rotor design comes straight from racing development. It acts like a centrifugal pump, drawing cool air through the disc to keep temperatures under control and minimize fade under repeated heavy braking. The result is a rotor that stays cooler, lasts longer, and performs consistently at the limit.
Each Girodisc setup combines a U.S.-sourced 6061-T6 aircraft-grade aluminum hat with a proprietary cast iron rotor ring — poured in the U.S. and machined entirely in-house for perfect runout and balance. The two pieces are connected using Girodisc’s fully floating mount system with precision drive pins and anti-noise hardware that allows proper thermal expansion without the rattle you get from most floating rotors.
What I really like about their design is how it integrates with the factory system — it’s a direct bolt-on replacement that works perfectly with the OE calipers and retains full ABS and bias functionality. When the iron rings eventually wear out, you just replace them — no need to buy an entirely new setup.
In short, Girodisc rotors are a smart, technically sound upgrade for anyone who wants true performance gains without compromising OEM reliability.

ABOUT THE PAD
When it comes to performance braking, few combinations are as effective as pairing Hawk’s DTC-70 compound up front with DTC-60 in the rear. It’s a setup that delivers the ideal balance of bite, torque, and control — engineered for drivers who demand consistency under the most extreme conditions.
The DTC-70 is built for high-deceleration, high-downforce applications. It provides exceptionally high torque and an aggressive initial bite, maintaining stability and performance through a 400°F–1,600°F range, with optimal results between 800°F and 1,200°F. It’s race-proven across everything from NASCAR and GT cars to Pro-Lite trucks — a pad that stays consistent, lap after lap.
The DTC-60 complements it perfectly at the rear. With slightly lower torque and superior release characteristics, it provides smooth modulation and stability under hard braking, even on lightweight or ABS-equipped setups. Its 700°F–1,100°F sweet spot keeps it responsive and consistent without excessive rotor wear.
Together, these compounds create a balanced, confidence-inspiring brake package — high torque up front, controlled modulation in the rear — delivering the kind of precision and feedback that define a proper performance braking system.
When paired with Girodisc’s two-piece floating rotors, this setup truly comes into its own. Because the DTC compounds generate significant heat under heavy braking, and Girodisc’s lightweight, ventilated iron rings with 72 curved vanes act like centrifugal pumps — pulling air through the disc to maintain consistent operating temperatures. The floating aluminum hat also isolates that heat from the hub and bearings, preventing distortion and maintaining pedal consistency even in extended track sessions.
This synergy between pad and rotor allows for precise thermal management, even pad deposition, and reduced unsprung mass — translating to sharper response, improved pedal feel, and greater overall braking efficiency. It’s a system designed not just to stop harder, but to stop smarter — giving users confidence that they’re running a truly engineered, balanced, and proven brake package.
