SLG - BMW E46 & Z4 Wilwood Dual Caliper Bracket Kits

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 ARP hardware which is stronger than competitors grade 12.9, and are all shipped directly from our door to yours. No BS, we stand by our product no matter what and offer a lifetime warranty. 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 trailing arm bolts alone, like our competitors bracket kits do. We also use an extra, 4th bolt, that goes in through the back of the arm for unsurpassed strength. A bonus feature 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.

All model brackets share the following:

• Billet aerospace 6061 aluminum construction
• Gold Anodizing
• ARP Hardware for connection to trailing arm, and 12.9 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, unlike comparable products
