BREMBO Gran Turismo Brake Kit - Lexus IS300 (Front) 2000-2005

This line is dedicated to the most demanding customers.  This braking system originates from the Racing components, consisting of a ventilated, integral or composite disc, available drilled or slotted, 4 and 8 piston aluminum calipers, a complete set of high performance brake pads, metal braid tubes and high quality small parts.

High Performance Friction Material
Aggressive pads that provide the highest level of performance.

Cross-Drilled or Slotted Discs
Clears gasses, cleans pads for better “bite”.

Mounting Brackets and Assembly Hardware
Aircraft quality included and pre-torqued specifications.

Stainless Steel Braided Brake Line
DOT/TÜV approved.

"Floating" Disc Mounting System with Billet Aluminum Hat
Reduce “Unsprung Weight” for better handling and reduces heat-related stress; increases brake performance and pedal feel.

Four, Six, or Eight Piston Cast Aluminum Calipers
Provide maximum braking force without the flex of sliding calipers.

Comparison between floating 2-piece and 1-piece discs
The floating disc mounting system, due to the aluminum alloy hat, reduces the “unsprung” weight for better handling and reduces heat-related stress: the mounting system is designed to allow a specific amount of float in both radial and axial directions. BREMBO has engineered special springs that are used on every other fastener in order to slightly preload the assembly.  This has been done to prevent excessive noise from the system during street use.  The one-piece discs (both for the Sport and GT Junior lines) are specifically designed in the goose-neck area to minimize thermal distortion and thus disc warping under severe use conditions.  The one-piece discs provide excellent stopping power ranging from everyday traffic conditions to more spirited high performance driving, and fit into the budget of any enthusiast.

Ventilation gap
It is a popular misconception that the slots or drillings in a disc determinate the direction of rotation.  In truth, for an internally vented disc, the geometry of the vanes dictates the direction of rotation.

There are 3 different ventilation types in use:
• Straight vanes
• Curved vanes
• Pillars

The straight vanes and the pillars are non-directional, and can be used on either side of the vehicle.  The curved vane disc, however, is directional.  A curved vane disc must be installed with the vanes running back from the inside to the outside diameters in the direction of rotation.  Orienting the disc in the manner creates a centrifugal pump.  The rotation of the disc causes air to be pumped from the center of the disc, through the vanes, and out through the outside diameter of the disc.  This enhances the disc’s ability to dissipate heat On some OEM applications, this standard is not satisfied: the use of directional discs means to manage two codes (left and right) per axle with some extra cost therefore it happens that a car manufacturer can use the same disc with curved vanes on both sides, losing part of the benefit in balance with lower costs.
