The Original BMW Dual Caliper Solution!Patent No.: 11,015,667 This dual caliper bracket kit is the easiest and least intrusive way to install a true Formula Drift style secondary/dual caliper hydraulic handbrake setup. Mad skids have never been easier! Don’t use an in-line system; they lead to constantly changing brake bias and inconsistent pedal feel. Our standalone dual caliper kits offer the best performance and easiest installation. Read below to find out how we offer the strongest kit on the market.    About: Our brackets are designed and machined by professional automotive engineers in the USA to be as strong as possible with no compromises, are manufactured in our own machine shop out of aerospace-grade 6061 aluminum to assure the highest quality, use high-end ARP hardware, and are all shipped directly from our door to yours. Feel free to reach out with any questions during your build.   Why Choose SLG Brackets?: Our brackets are designed to not put the force of the handbrake through the brake shield bolts alone. We special features for unsurpassed strength. A bonus is that our bracket kits always allow you to keep the factory rotors and never require you to remove the hub to install the kit.   Our brackets are different for every sub-model, as they all have slightly different trailing arms. By doing this we can individualize each bracket model to "grab" parts of each trailing arm, which are all different. For example; a part of our brackets goes through the hole that the original handbrake cable went, and has an extra 10mm bolt secure it from the back of the arm. This takes a large amount of load during a handbrake pull and reduces the risk of one of the smaller bolts breaking.   On top of that we use the factory e-brake pad posts and other machined surfaces on the trailing arm to further reduce the stress the bolts encounter. By doing all of this extra work and not just making a universal kit we ensure we offer the strongest bracket on the market.   E36 Non-M models use 2 piston Wilwood calipers.     E36 M3 models use 4 piston Wilwood calipers All model brackets share the following: Billet aerospace 6061 aluminum construction Computer modeled design and analysis Gold Anodizing  ARP Hardware for connection to trailing arm, and high grade hardware found in other locations Allows for use of factory wheel speed/ABS sensors Does not require the removal of axle, hub, or wheel bearing to install Requires removal of dust shield and factory e-brake system *Not for use on ti or Z3 models *Handbrake Line Kits sold separately* Install Instructions Remove caliper and rotor. Remove factory e-brake shoes, mechanisms, and cables. May be necessary to cut cables and punch it out of the trailing arm from the backside. Unbolt the dust shield and cut it, so you are able to bend it around the hub and remove it from the vehicle. Clean the trailing arm to remove rust and uneven surfaces. Bolt up the billet bracket to the trailing arm, using blue Loctite on the ARP hardware. Install the 10mm allen head screw into the bracket from the backside of the trailing arm, through the factory e-brake cable hole. Install brake rotor Reinstall primary caliper in factory location, and install secondary caliper to the bracket.
