Better materials, better processes, better discs

The technologies employed by DBA are at the forefront of brake manufacturing and enables consumers to clearly identify how DBA discs are ultimately superior. The processes adopted by DBA through clever engineering allow consistent and premium performance characteristics, aiding a fit-and-forget mentality enabling DBA brake discs to do what they do best, slow down vehicles time and time again.

Defining elements of DBA discs:

Dimensionally Precise – Most discs on the market are found to be ‘ground’ finished, but every DBA disc endures a special Cubic Boron Nitride (CBN) fine-turn process. The quality of the finish is measured as a surface roughness (engineering term Ra) in microns. One micron is 1 millionth of a metre (see diagram below).

DBA rotors are machined to a maximum of 1.8 Ra or less.
