Show original supplier description
The Ksport Slimline Big Brake Kit provides a significant upgrade to your Lexus IS300's braking system. This front kit is engineered with 350mm two-piece slotted rotors and 3-piston forged monoblock aluminum calipers for enhanced stopping power and heat dissipation. The kit includes SC5 Street Pads and CNC machined carbon steel brackets. Replacing your stock rubber lines, the included stainless steel brake lines minimize expansion under pressure, leading to a quicker pedal response and a firmer pedal feel. Ksport builds these big brake kits to order, so please allow 4-6 weeks for production and delivery. This kit is specifically designed for the 2000-2005 Lexus IS300. If you encounter any fitment issues, it is crucial to contact Ksport or the seller immediately to ensure a smooth resolution, especially before proceeding with installation.
