Drilled or slotted? Which disc brake pattern should you choose?

With the wide scale of different brake disc patterns, the question of which one is the most suitable for your use comes with great importance. We will try to explain 2 main types of the disc patterns (cross drilled & slotted) and list their pros and cons to help you make the right choice fitting your car and your specific driving conditions.

Drilled or slotted? Which disc brake pattern should you choose?

Based on your driving style you will find that each type of the brakes offers you different advantage. Every car is different, what is suitable for your light commercial vehicle may not work very well with your sports car.

Cross drilled pattern

Pros:

Cross drilled discs provide greater cooling capacity during braking thanks to increased number of out-gassing exit points allowing more brake pad friction gass to escape through. They also perform well in areas with more rainy climates as the holes provide more space for water to escape thus improving the bite and overall braking performance.

Enthusiasts who seek aesthetic improvement also tend to prefer the look of the cross drilled discs.

Cons:

While drilled rotors have a lot of great features, they may show uneven wear and develop cracks when exposed to extreme operating conditions. While performing well in general use in street vehicles, they do not withstand well repeated heat and cool cycles during the motorsport racing.

Recommended for street applications, daily drivers, light commercial, 4x4 and street SUV.

Slotted pattern

Pros:

Slotted rotors are suitable for more demanding conditions as they show greater mechanical resistance then cross drilled discs. The slotted design consists of a precise array of slots that form exit points for brake pad friction gass to escape through.

DBA mastered the unique design of Bi- and Tri-Symmetrical curved slots that dampen the vibration harmonics or noise, that’s commonly associated with traditional straight slot (groove) brake rotor designs and in result offer a quieter, responsive and smoother brake pedal feel.

Cons:

As the slotted brake rotors are more recommended for demanding conditions, their superior performance tend to bring shorter life of a brake pad as of the disc itself

Also when stopping from high speed there can be a noise that you might find unpleasant although this does not influence the braking performance of the disc

Recommended for all performance applications from street driving, 4×4 and SUV, light utility vehicles, track days, rally cars and armoured vehicles.

Both drilled and slotted design are made to guarantee greater heat dissipation in comparison to standard brake discs. Over four decades of manufacturing experience, research and development, DBA has positioned itself as a global leader in premium brake rotors manufacturing wide scale of different patterns to suit every driving need and condition.

With continuous improvements in engineering along with a thirst for innovation, DBA has managed to consistently redefine and deliver disc brakes solutions for an extensive range of vehicle applications and conditions.
