Decela Rotors (front)

Today's open wheel designs have made brakes a critical element in creating a "finished performance appearance"! In answer, Baer developed DecelaRotors as premium OE replacement rotors with slotted, crossdrilled and plated surfaces.

First crossdrilling, then slotting, originated from a need developed in the early days of disc brakes in road racing. The purpose is to provide gasses that build up between the rotor and pad surface an exit path. If left unaddressed the "out-gassing" of pads generate a pneumatic barrier between the rotor and the pad, effectively reducing friction and with it braking performance. These gasses are generated when elements used in manufacturing pads reach extreme temperatures frequently experienced in racing. 

Today's compounds and burnishing techniques in manufacturing have largely eliminated the effects of out-gassing in modern pads. The engineers at Porsche, Mercedes, Ferrari and others have this knowledge, however racing appearance and heritage that is visually evident with crossdrilled rotors is a finishing touch that delivers satisfying esthetics.

Each hole drilled in a Baer DecelaRotor is carefully located ventilated rotors. This minimizes potential surface fissures (cracks) and maintains proper rotor balance. Some competitors imply or directly state, "slotting does not generate an increase in stress to the surface of the rotor like crossdrilling does".

This is simply not true!

Any machine modification to rotor surfaces creates a stress riser. Baer backs DecelaRotor with the industries best warranty, which itself is backed by Baer's 15+ year reputation for delivering premium brake products to satisfied customers. Many also imply or state outright, "slotted or drilled rotors deliver significant performance stopping improvements". Quantifiable stopping improvements are generated from increasing brake torque. Increasing leverage (larger dia rotors), increased clamping force (caliper upgrades) or improving friction itself (higher mu pad compound) are the commonly accepted ways to attain bolt-on improvements in braking performance.
