DBA4909S-1170XP Performance Front Brake Package

The DBA4909S-1170XP package combines DBA’s 4000 Series T3 front brake discs with Xtreme Performance DB1170XP front brake pads, providing a significant performance upgrade over standard replacement braking components.

The brake discs use DBA’s XG-150 high-carbon alloyed iron and Thermal Stability Profiling (TSP) technology. The discs also feature DBA’s patented Kangaroo Paw ventilation system, designed to improve heat management and maintain consistent braking performance under demanding conditions.

The T3 tri-symmetrical slot design provides additional friction material dust and gas exit points compared with conventional slot designs, helping maintain consistent pedal feel during repeated hard braking. DBA states that the T3 design is suitable for high-performance street driving and demanding applications.

The package is completed by DB1170XP Xtreme Performance front brake pads, developed for high-temperature performance and consistent friction characteristics. DBA’s application data lists these pads for several Nissan Sumitomo-caliper applications including the 200SX S14, Silvia S14/S15, 300ZX Z32 and Skyline R32/R33/R34 applications, although the brake disc determines which of those vehicles are suitable for this particular package.

What’s Included?

The DBA4909S-1170XP package consists of:

• DBA 4000 Series T3 front brake discs
• DBA part number 4909S
• DBA DB1170XP Xtreme Performance front brake pads
• Front axle application
• Slotted brake disc design
• Vented brake discs
• Kangaroo Paw ventilation
• High-carbon XG-150 alloyed iron construction

Important: The DBA4909S rotor is normally supplied as an individual rotor by DBA, while vehicle applications require 2 front rotors per car. Confirm the package quantity with your supplier before listing the number of discs included. DBA specifies 2 rotors per vehicle for the front axle.

DBA 4000 Series T3 Disc Features

XG-150 High-Carbon Alloyed Iron

The DBA 4000 Series uses high-carbon alloyed iron designed to withstand the increased heat and stress generated during repeated hard braking.

Thermal Stability Profiling

DBA’s TSP process is designed to improve thermal stability and reduce the likelihood of distortion under severe braking conditions.

Kangaroo Paw Ventilation

The rotor uses DBA’s Kangaroo Paw internal ventilation system.

The rotor contains a series of diamond and teardrop-shaped ventilation pillars designed to improve airflow through the disc and assist heat dissipation.

T3 Tri-Symmetrical Slots

DBA’s T3 slot configuration is designed to:

• Increase friction material gas escape points
• Help clear brake dust
• Maintain consistent braking response
• Improve pedal feel during repeated braking
• Provide consistent friction characteristics

DBA describes the T3 design as suitable for high-performance street cars and other demanding applications.

Why Choose DBA 4000 T3?

The DBA 4000 Series T3 is designed for drivers who want more capable braking hardware than a conventional OE replacement disc.

The combination of high-carbon metallurgy, thermal treatment, Kangaroo Paw ventilation and T3 slotting makes this setup particularly suited to performance Nissan applications where repeated heavy braking can generate substantially more heat than normal road driving.

The included DB1170XP Xtreme Performance pads further increase the performance focus of the package.

Confirmed Package Fitment

This is the important part for your Performance Cars Parts UK fitment system.

Because this is a 4909S + DB1170XP combination, I would not add every vehicle that either component individually fits.

The strongest overlapping Nissan applications are:

Nissan 200SX S14

• 1993–1999
• 2.0 Turbo
• Sumitomo front caliper

Nissan Silvia S14

• 1993–1999
• 2.0 Turbo
• Sumitomo front caliper

Nissan Silvia S15

• 1999–2002
• 2.0 Turbo
• Sumitomo front caliper

Nissan 300ZX Z32
