WINMAX W7 Compound: Metallic Friction: 0.48 - 0.53Mu Temp range: 100 - 850degC Competition only Brake Pads Semi-Professional motorsport use only Professional class brake pads that have the highest heat tolerance and effectiveness in the WinmaX range as well as break-neck coefficient of friction stopping power. These pads are designed to work with competition vehicles with the booster removed. W7 is a circuit racing brake pad that once some initial temperature is introduced, works right through to very high temperatures. A good pre-bedding procedure and correct temperature window is needed for maximum efficiency. Higher pad wear than W6.5 compound. This pad is ideal for: Competition, high level motorsport. Tarmac Rally heavy, powerful vehicles Why buy this product? Professional level competition brake pads Highest heat tolerance / fade resistance. Designed to work without booster if necessary Very high torque throughout the stop Excellent modulation and feel Works from low temperatures so suitable for rally / sprint / hill climb What you get: 1 part number = 1 set of pads. In most cases this is 4 pads per box. If your calipers take more than 2 pads per caliper (E.g Audi RS4), the part number you buy will include all the pads you need to service the axle set of calipers. Also included is bedding instructions to help you get the most out of your new pads. Brake pad product notes: Shims and Wear sensors Our brake pad products are designed for high performance and competition use. Therefore, we do not always provide ancillary parts such as wear sensors or anti-squeal shims on some of the WinmaX and CIRCO range. Ancillary parts are provided in some cases depending on the pad specification and fitment. Anti-Squeal shims are available for some shapes as separate items on this website. If you are unsure about any of this, please contact the us for confirmation. Fitment FRONT, REAR or UNIVERSAL? Our brake pad products are engineered to replace OEM parts with higher performance friction. Many pad shapes are designed to be installed in only front or rear. However, there are many pad shapes in the automotive world that are shared across multiple vehicle and caliper makes and models. In many cases these shapes are installed in the front on one vehicle, but the same shape is used in the rear of another. In other cases, the same pad shape is used in both front AND rear. If a brake pad is known to be used for front and/or rear, we refer to it as UNIVERSAL. If unsure about the fitment when purchasing, please check with us.
