Cobalt Friction XR Series Brake Pads (Rear): 97-01 Acura Integra TYPE-R
**Please not that most Cobalt Friction brake pads are made to order with a 5-7 business day lead time**
Cobalt XR1 is an extremely high torque material with a rapid, yet controlled, transition from an aggressive initial bite to a medium-high, linear rising torque curve. Excellent friction stability and consistency coupled with very good modulation, threshold control and release characteristics over the industry's broadest operating temperature range. The XR1 material has unmatched disc life and finish versus any other competing friction material of comparable torque (i.e. within ±10% of XR1's initial and average torque levels). Effectively bridges the gap between "sprint" and "endurance" materials, providing an optimal balance of ultimate high torque and very good wear rates. Equally well-suited for a wide range of platforms, including those with active aerodynamic profiles as well as limited downforce applications, and/or ABS-equipped as well as non-ABS vehicles, due to the direct line pressure to generated torque relationship.
Cobalt XR2 is a high torque material featuring an initial
bite that is 8-10% lower than XR1, but with the same controlled transition to a
linear, rising torque curve. Improved modulation, threshold control and release
characteristics make the XR2 particularly well-suited for chassis and tire
combinations which do not respond well to excessive initial brake energy, but
still require a high average torque level. Similarly, vehicles normally
equipped with XR1 can move directly to the XR2 when low-grip conditions present
themselves unexpectedly (e.g. qualifying in the dry, but rain/wet conditions on
race day) without sacrificing or experiencing a change in pedal feel, consistency,
or brake capacity. As with all Cobalt Friction XR-Series Carbon-Ceramic
friction materials, the XR2 does not require any bedding¹, and will deliver
100% consistent performance within 1-2 laps, while still maintaining a
superior, uniform disc finish.
Cobalt XR3 is a versatile, medium-high torque material with a solid initial bite and a slightly rising torque curve. Unsurpassed cold performance, torque stability, consistency and modulation/release for this level of friction make the XR3 an ideal compound for Club Racing and Track Day/HPDE customers (i.e. SCCA, BMWCCA, NASA, etc.), particular in moderate to lower inertia vehicles. As a testament to its well-rounded performance, the Cobalt XR3 material set more poles and won more races in the SCCA Pro Racing Playboy Mazda MX-5 Cup Series than all other brake pad manufacturers combined in the first year of open, non-spec brake pad selection. Also recommended for rear-axle use on vehicles over 2800lbs to deliver optimal straight-line braking performance, stability and controlled rotation while trailbraking.
Cobalt XR4 is a medium torque compound sharing a similar application basis as our popular XR3 material, but at lower overall friction levels. With a slightly rising torque curve at low to moderate line pressures, transitioning to a virtually flat profile at higher line pressures and temperatures, the XR4 is primarily a rear-axle compound for vehicles under 2800lbs. However, the excellent cold performance, friction stability and consistency of the XR4 also make it a class-leading autocross compound on vehicles up to 3200lbs.
Cobalt XR5 is a specialized low-medium torque material
designed specifically for rear-axle applications on vehicles exhibiting a rapid
rate and high magnitude of weight transfer under braking, e.g. FWD or
low-inertia RWD vehicles. Solid initial bite with a perfectly flat torque
profile, transitioning to a negative slope (i.e. negative torque gain versus
temperature) virtually eliminates rear lock-up. Cobalt XR5 is the rear-axle
compound of choice for championship winning drivers and teams in Grand Am
Continental Tire Series, SCCA Spec-Miata, Showroom Stock and IT classes.
