Big Ol’ Boy “B.O.B.” Stainless Steel Inboard Brake Rotor – Built for Maximum Stopping Power

Engineered for high-performance in sprint car racing. The B.O.B. Sprint Car Stainless Steel Inboard Brake Rotor delivers unmatched strength and braking precision. Measures 5/8-inch wide with a 12.200-inch outer diameter. Is always precision-machined from solid billet alloy round bar—never cast—and is magnetic, a proprietary feature exclusive to Smith Ti.

Each rotor undergoes advanced CNC machining, in-house stress relief, and wire EDM venting, ensuring maximum durability and heat dissipation lap after lap. Just like its titanium counterpart, this stainless steel rotor stands up to the toughest racing conditions without compromise.

The innovative slot design effectively wipes the full brake pad surface, preventing glazing while reducing pad wear—delivering consistent braking power and extended component life.

Pair it with our Big Boy Caliper for the ultimate braking system in sprint car racing. Trusted by top-tier teams for its race-winning performance, reliability, and engineering excellence.
