2X DBA Front Disc Brake Rotor For Land Rover Discovery 2.5L,3.5L V8 12L 23D 37D 20L

Description

DBA Front Disc Brake Rotor - Pair

4000 SERIES XS Gold provides all the benefits of 4000 Series, with a premium non directional cross drilled and slotted design, plus an attractive gold finish on the rotor hub.
The introduction of our unique cross drilled and slotted design increases the number of exit points, allowing more brake pad friction dust and gases to escape through both the cross drilled holes and slots, resulting in better braking performance.
While providing a similar performance benefit to the T3 slot, the XS Gold is a popular alternative for show cars.
Drilled rotor configurations are not recommended for heavy off-road or track day usage.

Features

1.Surface Design Slots and/or chamfered drill holes facilitate the exit of friction dust and gasses, for a quieter and more responsive pedal feel.*
2.Anti Rust Painted non-friction areas to prevent rust and enhance appearance.
3.BI-Directional Use Symmetrical slotting and/or drilling for universal left/right use.*
4.Thermal Stability Profiling Heat treatment cycles realign the microstructure of the iron, resulting in increased rotor stability and durability.
5.Thermal Efficiency Centre-split core castings for increased heat transfer and thermal efficiency.
6.CBN Cubic Boron Nitride (CBN) machine turned finish, minimising disc thickness variation and the potential for pad "knock" and resulting premature wear.
7.Thermographic Heat Paint Paint markings change colour at specific temperature thresholds to assist with the monitoring of braking temperatures and rotor fatigue.
8.High Carbon Alloyed Iron Formulation allows for optimal interaction with DBA’s thermal stability profiling (TSP). Increases the capacity of the rotor to handle constant and extreme heat over prolonged periods.
9.Kangaroo Paw Unique Kangaroo Paw vane design for up to 20% better heat dissipation, increasing braking effectiveness and prolonging brake life.*

Information About Disc Rotor

Changing brake discs at regular intervals is of extreme importance to be sure one’s car braking system delivers high end performance under challenging weather.

We have many brake disc rotor manufacturers across the globe. Extramile offer you the best brands and rotor models. Brands include Bosch, Delphi, AC Delco, RAE, RDA, Protex and few more to add.

If you are thinking of changing the disc rotor, we must determine which type of rotors the vehicle uses. There are four types Rotors

Blank & Smooth - Blank and smooth rotors are what you'll find on most passenger vehicles and feature a smooth, blank metal surface all the way around the rotor
Drilled - Drilled rotors feature drilled holes around the metal surface
Slotted - Slotted rotors feature long "slots" or lines in the metal surface
Drilled & Slotted - Drilled and slotted rotors combine the drilled holes and slots for enhanced performance

Blank & Smooth

As stated above, blank and smooth rotors are what you'll commonly find on most new passenger vehicles. Keep in mind that oe-specific rotors have a basic and premium option, and it all has to do with how they're manufactured. Unless you're a super aggressive driver or you're driving a luxury vehicle, blank rotors are a great choice for your vehicle.

Basic oe-specific rotors are traditionally made from recycled steel and a lot of times don't perform as well as your original equipment manufacturer (OEM) rotors due to thicker internal fins, which in turn impact the cooling abilities of your rotors. If you're going to use premium ceramic brake pads with your new rotors, don't pair them with a basic set of rotors. Basic rotors will also end up reducing the life of your new pads, as they'll wear down quicker due to the increased heat.

Drilled Rotors

As the name suggests, drilled rotors have holes drilled throughout the surface. These holes allow water, dust, and heat to easily dissipate off the surface of the rotor. Drilled rotors are a great choice for drivers that live in wetter climates as they'll help increase stopping power in wet, rainy conditions. If you're looking at drilled rotors for a performance vehicle, you'll want to stay away. Drilled rotors don't work well under high-heat and can fail pretty quickly in a race-type driving scenario.

Slotted Rotors

As mentioned before, slotted rotors feature slots around the exterior surface of the rotor. They're a great choice for heavy-duty trucks and SUVs, especially those that need improved stopping power when towing or hauling. The slots are designed to draw more air in between the pad and rotor surface, which improves cooling and heat dispersion. They're also designed to help remove excess brake debris and pad glaze that can occur at higher temperatures. While they are more efficient in a few ways, they come with the downside of not lasting as long, which also affects the life of your pads.

Drilled & Slotted Rotors

Lastly, drilled and slotted rotors are primarily designed for performance vehicles, like sports cars, that need enhanced cooling and heat dispersion. This type of rotor was designed to improve braking at high speeds during racing or track days.
