345mm BREMBO 4P Brake System Kit to fit VW GOLF 5 6 AUDI A3 8P. A set of quality and powerful products selected and produced by MODOSPORT to provide stunning stopping power for the VW GOLF 5 6 and AUDI A3 8P. This Stage 2 is made for those who are looking for the highest standards to raise race needs to the next level of high performance. To improve product performance and reliability, MODOSPORT Design and Engineering department uses Finite Element Analysis (FEA) in product development of mounting brackets to simulate how the products react in real-world conditions and ensure that the design is able to perform to specifications prior to manufacturing. The Kit was also been track/road tested prior to public release. Mounting brackets are aerospace grade anodized aluminum CNC machined, combining high strength, toughness, stress corrosion and cracking resistance. The ventilated 345mm disc enhance stopping power and improve the cooling performance over the standard 280mm disc. The greater air gap thickness creates a greater airflow as the rotor spun, resulting in cooler rotor temperatures. Also the air intake of the ventilating space is made from the inside of the car, which allow more advantages in the installation of brake cooling duct to improve cooling performance in the vanes. To further improve braking performance there are optional discs, drilled or slotted, designed to have a superior heat dissipation and contain any risk of disc deformation, and also to have a higher friction coefficient.
