The new Ksport Slimline Audi A3 Quattro Big Brake Kit ensures that you can upgrade to a Big Brake Kit and have it fit most factory wheels, or wheels with very limited brake caliper clearance. The popularity of aggressive fitting wheels on factory body vehicles has never been more popular than it is today. In most cases, aftermarket big brake kits aren’t compatible with this style. Large multi-piston brake calipers just don’t fit within the very limited spacing between the larger brake caliper and the back of the wheel. Ksport has developed the Slimline Caliper with this issue in mind, a design that’s based on the OEM single-side floating piston caliper thickness.
The Slimline Big Brake systems are designed for easy installation with minimal tools required in most applications. Kits come standard with everything needed for installation, including: Calipers, Floating Brake Disc, Brake Pads, and all required hardware. For those looking for a brake kit that aligns with aggressive fitting wheels on a factory body vehicle, the Slimline Audi A3 Quattro Big Brake Kit is the ideal choice.
This system is appropriate for 17″ wheels and above.
Lightweight Forged One-Piece Caliper
Our extremely lightweight forged one-piece calipers feature 1-piece construction from a solid billet of aerospace quality aluminum rather than being cast or welded together. This provides perfectly even thicknesses and strength over every part of the Caliper block to eliminate weak spots which lead to fracturing, warpage, and failure over time. Caliper pistons are made from aluminum and protected with heavy-duty seals designed to handle racetrack temperatures. Better heat transference ensures pistons slide smoothly and evenly without drag, and aluminum construction ensures caliper operation remains uncompromised by corrosion over time. Additionally, an opposed-piston design ensures brake pad grip and wear remain consistent on both sides of the rotor. High Temperature Seals, Titanium Brake Pad Retainer Clips and Stainless-Steel Brake Pad Wear Plates are also standard on each Caliper design in the Slimline Audi A3 Quattro Big Brake Kit.
Two-Piece Rotor Design
All Slimline Big Brake systems feature two-piece rotors to provide light weight, fade-free performance and effective grip on the racetrack and comfortable, easy-to-use operation under normal driving conditions. The rotor design is extremely lightweight when compared to OEM one-piece rotors, commonly weighing up to 50% less than OEM rotors of the same size. Lightweight center sections crafted from 6061-T6 aircraft-grade aluminum give you the benefit of lower rotational mass – making wheels easier to stop and giving you the instant snap of brake response that’s proper for high performance driving. Because the outer section of the two-piece rotor can expand and contract independently from the center section, chances of the entire rotor warping due to heat buildup are greatly reduced. And since aluminum is a better conductor of heat, the center sections serve as effective heat sinks by passing heat away faster to the air and to the hub assembly.
Combined, these two factors give them a much longer service life than traditional one-piece rotors. Every rotor is always heat treated and balanced before shipment for the best performance. Since Cross Drilled rotors run cooler than slotted, we recommend them for daily driven vehicles. For vehicles that will be seeing more track use than daily driving, we recommend Slotted Rotors.
We recommend Cross Drilled rotors for daily driven vehicles since they tend to run cooler than slotted. Both rotor types have increased “bite” over stock and continuously clean and refresh the pad surface.
Slotted rotors feature grooves on the rotor surface to wipe away heat, dust, and gases. We recommend slotted rotors for vehicles that will be seeing more track use.
The Slimline Big Brake System utilizes a 3 Pot Caliper. The single-side piston caliper design maintains the same styling as our multi-piston caliper’s appearance.
Each Slimline Big Brake kit comes with CNC machined Carbon Steel caliper brackets. Due to our calipers being much larger than OEM, these brackets help the system bolt right up to your OEM caliper bracket location.
Options to upgrade to a Titanium Center Bell and Hardware or Twin Color Anodized Center Bell are available for further customization of your brake system.
All our Slimline brake systems feature extremely lightweight two-piece rotors. It is common for our rotors to weigh up to 50% less than OEM rotors of the same size.
D.O.T compliant stainless-steel braided brake lines are standard in all our brake kits. The Stainless-Steel brake lines stop expansion under pressure, provide a quicker pedal response, and have a firmer pedal feel over stock rubber lines.
The NAOC Ceramic pads give optimal braking performance under street and occasional track conditions. The pads reduce the amount of brake dust by 50% or more when compared to race pads and greatly reduce the amount of noise and wear on the rotor. Optimal operating temperatures between 194°F – 1022°F for fast warm up under normal driving conditions. Average coefficient of friction is between .46 and .53.
SC5 Street Pads are standard equipment, however, the option to upgrade to RCI Race Pads is available. These Carbon Metallic race pads give you the best stopping power under extreme track conditions. Optimal operating temperatures are between 482°F – 1472°F. RCI Race Pads not recommended for street use due to the high working temperature needed for optimal performance.
Brake calipers come standard in painted colors such as Orange, Red, Black and Yellow. There is also an option to upgrade to premium high polish finishes in Silver, Gold and Titanium as well as Glassy/Hard Anodized Colors. Over 20,000 custom color finishes are also available for an additional fee leaving the options nearly limitless.
All Ksport Big Brake Kits come standard with a 12-month warranty which covers manufacturer defects.
