Whether it is installing new wider wheels, tires, brake ducts, shocks, or springs, there could be a rubbing issue on the inside of your fender well. Our rack stops will help protect your investment. Rack stops are spacers that install inside of the tie rod and limits the amount of steering travel. You can save the costs of replacing rubbing tires, worn out brake ducts, cut shock reservoir hoses, and broken underside plastic panels. There is also the added benefit of knowing you can turn the steering wheel to full lock and not be worried that the wheels will rub. Our rack stop length is the approximate length that will be removed from the outside tire wall�s path. For example, if a 16mm rack stop is used, there will be 16mm more clearance for a brake duct between the fender well and the edge of the tire. Included with this kit: 2 Delrin rack stops, 1 black (driver�s side), 1 white (passenger�s side), 2 Locking plates (only needed on E36), 4 zip ties, detailed instructions.

Since 2010, Advanced Auto Fabrication has been producing and developing both parts and full fledged race cars. Their knowledge base covers a wide range of vehicles both domestic and imported. In the specific case of BMW, the team at AAF has a particular affinity for building and designing components for BMW race cars. These Backing Plates by Advanced Auto Fabrication feature a large “Pocket” to allow for more efficient air flow into the brake hat. This allows air to travel through the vents in the rotor. AAF's Backing Plate is the full size of the rotor and is a heat shield for the shocks and ball joints. Heating of your shock oil causes oil thinning, which changes the shock dampening characteristics. Protecting your ball joints from heat will improve longevity and prevent premature wear. The backing plates are powder coated black for extra durability and attractive aesthetics. They replace the OEM dust shields, and will need to be removed before installation.

Since 2010, Advanced Auto Fabrication has been producing and developing both parts and full fledged race cars. Their knowledge base covers a wide range of vehicles both domestic and imported. In the specific case of BMW, the team at AAF has a particular affinity for building and designing components for BMW race cars. AAF's brake duct adapters slide directly over the OEM e30 brake duct inlets. They suggest using a strong 2 part bonding adhesive to attach the duct adapters to the OEM brake duct inlet. This is ideal for maximum airflow, as it does not intrude into the air duct, and will create an air-tight seal around the joint. These are the perfect answer for your brake duct kit.

AAF's Backing Plate is the full size of the rotor and is a heat shield for the shocks and ball joints. Heating of your shock oil causes oil thinning, which changes the shock dampening characteristics. Protecting your ball joints from heat will improve longevity and prevent premature wear. The backing plates are powder coated black for extra durability and attractive aesthetics. They replace the OEM dust shields, and will need to be removed before installation.

In the specific case of BMW, the team at AAF has a particular affinity for building and designing components for BMW race cars. AAF is proud to introduce their redesigned AAF E46 (non-M) Brake Cooling Duct Kit! Features: Extremely Light Weight – Less than 4 lbs in total! Ultra-High Airflow Inlets Tight Turning Radius Easy and Quick To Install Inexpensive to Buy and Maintain Durable for Racing Conditions Designed strong and lightweight these brake duct inlets include a massive 4' inlet. Ultimately this aids in providing higher airspeed and pressure to the brake rotor and thus better brake cooling. Inlets are manufactured by AAF in-house with a 3D printer to provide a strong and inexpensive part. Brake duct tubes included in this kit are made from lightweight and strong ABS plastic. Shaped for optimized airflow, these tubes also provide the ability for a tight turning radius even with large racing tires. Per AAF: for a SPEC E46 with the spec 255 Toyo tire, you can turn 1.5 turns from straight without hitting the tubes, which is more than enough for driving around the paddock. The tubes taper down to a 3' flex hose, to remain legal for SE46. Included in the kit are AAF's Brake Backing Plates as well.

Race German has devoted themselves to providing quality products for late model BMWs that cover both street and track applications. Race German has now grown their catalog to a wide variety of models and products geared towards keeping your car looking and running nice. Cooling your brakes is essential for high endurance racing, or track days. Your brakes tend to fade after a 15 minute session on track, so Race German has developed a way to cool them. The late model E30 bumper already has inlets for brake cooling, but an adapter is needed to convert the square outlet to a 3" outlet for common brake ducting. These E30 brake duct inlet adapters are CAD designed and 3D printed here in the USA. They perfectly fit around the OEM E30 inlet duct and convert to the 3" outlet you need. There are holes printed in the ducts to secure them with provided zip ties so they do not fall out. **3D printed parts can have minor imperfections.

This is AutoTecknic's newly developed dry carbon fiber competition brake air ducts for the F82 and F83 M4. Similar to the brake air ducts found on the factory GT4 race car, it's designed to mount directly onto the front bumper. Dry carbon fiber's name comes from its manufacturing process. Dry carbon fiber is formed by using a "pre-preg" or impregnated piece of carbon materials. This piece of carbon is first placed into a mold, and then into a sealed autoclave to properly cure. This particular method creates the least amount of waste and forms a lighter version of carbon than the “wet” method. The autoclave vacuuming process of making dry carbon means that there are fewer pinholes and virtually no air pockets that form in the carbon. Dry carbon is the highest-quality version of carbon fiber products that are produced. Note: Modification is required to the bumper prior to installation.

Overheating your brakes can end an entire weekend at the track and is the most common reason for premature brake failure and wear. Hi-Flow Molded ABS Cooling Ductwork: The HARD Motorsport Brake Cooling DUCT kit is designed for maximum efficiency specifically for the BMW E36. Race-inspired by modern duct design of top motorsport teams and manufacturers. Easy Mounting / Removable Front Bumper: Because the ducts are supported by the frame rail, you can remove your entire front bumper without the need of disconnecting ANY part of your brake cooling system. No need to fumble with bolts, screws, and duct clamps, or unintentionally ripping out your flex tubing in the process. No need for extra inlets: The kit provides all that you need for mounting brake cooling ducts directly to factory mounting points on the frame rail of your BMW E36 M3. These ducts draw cold air directly from the design of the bumper. Our quality ABS plastic molded ducts are designed to endure the rigors of racing. Durable and easy to manage. No need for all that flex hose: While our kit reduces the area of interference, space is limited, so contact may still occur at full lock.** However, our kit uses a fraction of the length of flex tube over any other kit, so replacing this short hose is much easier on a budget and is a time saver in the paddock. Features: Left and Right contour-molded ABS chamber ducts/inlets Left and Right HARD aluminum mounting brackets/abrasion plate
