Description
DBA 4000 Series discs are single-piece performance brake discs, cast from DBA’s XG150 high carbon alloyed iron for greater thermal capacity, reduced fade and a longer service life than standard replacement discs. Supplied as a pair (2 discs) for one axle.
Features & Benefits
- Kangaroo Paw – 144 diamond and tear drop pillar ventilation system – Increased surface area resulting in greater heat dissipation – Minimises brake fade and increases braking effectiveness
- Increased surface area resulting in greater heat dissipation – Prolongs service life for both pads and discs. Reduces mechanical damage and associated costs
- XG150 High Carbon Alloyed Iron – An increase in thermal capacity property allows the disc to handle constant extremes of heat over extended periods of time – Minimises warping and cracking and prolongs the service life of the disc
- Paint protection on non-friction areas – Reduces corrosion – Stops any unsightly rust formation
- Enhances appearance – Adds value to the product
- CBN (Cubic Boron Nitride) machine turned – Reduced DTV (Disc thickness variation) and parallelism – Less occurrence of brake shudder or brake pedal
Ideal for enthusiasts looking for an upgrade over stock discs.
Premium non-directional cross-drilled and slotted design of DBA brake discs increases the number of outgassing exit points allowing more brake pad friction gasses to escape through.
Brake discs from DBA Street Series feature with “Kangaroo Paw” – 144 diamond and tear drop pillar ventilation system. Increased surface area results in greater heat dissipation and thus minimises brake fade and increases braking effectiveness of disc brake. CBN (Cubic Boron Nitride) machine turned reduces DTV (Disc thickness variation) and parallelism which brings less occurrence of brake shudder or brake pedal ‘judder’.
While providing a similar performance benefit to the T3 slot, the 4000 XS Series is a popular alternative for open wheel and show cars. We recommend the T3 slot design for more intensive braking applications.
