The “BOB” – Big Ol’ Boy Sprint Car Titanium Inboard BIG Brake System

The Ultimate in Stopping Power. Engineered for Performance.

Introducing the Sprint Car Titanium Inboard BIG Brake System, “The BOB” – Big Ol’ Boy, our most powerful and advanced sprint car brake system yet. Designed for drivers who demand performance, durability, and unmatched stopping power, this system takes braking to the next level.

Built to Run Hard. Engineered to Stop Faster.

At the heart of the system is a 12.2″ x .625″ titanium inboard rotor (6AL4V grade), weighing just 3.98 lbs. It features wider internal vents and stiffening ribs, delivering double the cooling capacity to prevent overheating—even in the most extreme racing conditions.

Stiffer Caliper. Smoother Stops.

The radial-mount inboard caliper features wider slots to match the rotor and a larger, stiffer body. That added stiffness gives you:

• More even brake pad wear

• Sharper, more consistent pedal feel

• Virtually no brake fade

And thanks to the radial mount, you can remove it easily for bleeding or maintenance.

Premium Materials. Proven Performance.

Just like all Smith Titanium brake systems, the “BOB” includes:

• 7075 billet aluminum calipers, coated in Ano III black to resist chemical wear

• All-titanium bolts, pistons, and fittings

• Brake pads and lines included

• Proven performance on both our in-house dyno and the track

We’re the only brake manufacturer laser-focused on sprint car brake performance—testing, tuning, and pushing the limits every single day.
