For those wanting to move away from EDC for aftermarket suspension systems or coilover setups, the EDC monitoring can be a bit obtrusive as this type of monitoring is no longer required – resulting in numerous error messages thinking the system has malfunctioned. This EDC Emulation Module installs in less than 15 minutes and will fully emulate a fully active EDC environment when activated. Module can be activated/deactivated by via the integrated mini USB port within the module housing.

The Macht Schnell EDC Emulation Module is possible of the following features:
  • The ability to run aftermarket racing suspension/coilover setups in which EDC monitoring is not required
  • Compatible with iDrive and non-iDrive systems
  • Easy 15-minute installation process with no wire cutting
  • Proper emulation of the EDC monitoring system
  • No dealer visits or coding required after installation
  • Completely removable at any time

    Note: The Macht Schnell EDC Emulation Module will disable the EDC monitoring system supplied by BMW. Once disabled the behavior of the car will change and the driver will need to adjust his/her skill and technique. For this reason, this module is not intended for street vehicles and its use may result in injury or even death if proper conditions and procedures are not followed.
    Will not work on vehicles equiped with BMW's Dynamic Drive system.

    This item fits the following BMWs:
    2008-2011 E90 BMW M3 Sedan
    2008-2013 E92 BMW M3 Coupe

    This is the front upper right control arm with the outer ball joint pointing down. This replacement fits E82 1M Coupe and E90/E92/E93 M3 models. This control arm includes the inner, pressed-in bushing and outer ball joint. This part can also be used as an upgrade on non-M E82, E9X, and E89 Z4 models. The inner bushing on the M3 arm is a solid rubber instead of the fluid-filled non-M design. This solid rubber part will last longer and be more responsive thanks to less deflection in the bushing. The M3 arm is a direct replacement for the stock non-M part.

    The latest innovative design from the expert engineers at AST Suspension is a solution for BMW owners seeking additional camber adjustment while retaining the factory struts. AST Suspension’s lowering spring and adjustable lowering spring sets can be combined with the camber-adjustable top mounts, meaning customers who have already equipped their vehicles with those components can now improve camber adjustability without losing the electronic dampers’ OE functionality. These new top mounts provide an additional 0° to -4.2° of camber adjustment, improving on factory adjustments done via the OE arms. AST Suspension opted for solid bushings made from 7075 high-grade aluminum with stainless steel inserts, manufactured in Japan. AST Suspension has employed these bearings in various applications for over 25 years, and they are trusted for their long-lasting anti-wear characteristics that have led to success in endurance racing. As an added benefit, these motorsport-quality bearings are effectively silent, preserving factory NVH. AST Suspension specializes in producing suspension components for vehicles serving regular street use and competition purposes such as race, rally, autocross, and more. The company has continuously evolved since its establishment in 2000 and has always taken pride in its work. By combining in-house design and production with technical know-how, industry experience, and road-and-track testing, AST Suspension consistently produces exceptional suspension components at a competitive price. Features: Adjustment from 0 degrees to -4.2 degrees of camber Retains full functionality of OE dampers Compatible with AST Lowering Springs and Adjustable Lowering Springs

    One of the tricks for getting your BMW to handle better is to add negative camber to the front wheels. This will put more of the tire's width in contact with the ground during cornering. With more rubber there is more grip. BMWs typically have less camber in the front to create understeer. But if you're running a stock setup on the track or autocross you are giving up speed and time as the front tires run out of grip sooner than they should. Made from aircraft grade aluminium, with stainless steels strut inserts and hardware for the ultimate in durability for street or track use. The built in reinforcement plate reduces the stress on the shock tower to reduce the chance of the shock towers tearing. With a maximum adjustment rang of -1.5 degrees camber per side, these plates will allow you to get your suspension right where you need it. NOTE: Will not fit with Bilstein Struts/Shocks. Can only be used with Linear style springs. Will not fit OE-Style Progressive / Barrel style springs. Fits the following BMW's 1992-1999 E36 BMW - 318ti 318i/is/ic 323i/is/ic 325i/is 328i/is/ic M3 2006-2013 E9X BMW - 325i/xi 328i/xi 330i/xi 335i/is/ix M3

    The OE thrust plate is more than just a belly panel that covers your oil pan; it plays a crucial role in chassis rigidity, impact safety, and handling dynamics. BMW emphasizes that a vehicle should not be driven or moved without the thrust panel in place due to its importance.

    Inspired by BMW's upgrade of the front bumper carrier on the E46 M3 from aluminum to Kevlar during their LCI update, we have made a similar enhancement to the thrust plate with our RKP Carbon Front Thrust Panel.

    Product Details:

    Multi-layered for optimal rigidity and durability 20% stiffer and 50% lighter than the OE panel Reflective exhaust heat shielding included Replaces the large, heavy aluminum OE panel

    Macht Schnell's aluminum bushing kit will breathe new life into aging 1M's and M3's, affixing the car's rear subframe and differential to the chassis. Rubber subframe bushings in the E9x M3 and E82 1M from the factory are soft, and yield under hard driving resulting in ever-changing suspension geometry and alignment specs. By limiting the movement of both the car's subframe and differential, these solid bushings will give the rear of the car a tremendously planted and confident feel.

    The front springs on the 2004-2010 E83 X3 models have a chronic broken spring problem. If it hasn't happened to you yet it will. Springs are nothing more than exposed steel and they rust easily. After a while a section of the spring actually breaks off. Typically the X3 was popular in markets with heavy salt and moisture anyway and water can pool in the bottom spring pad.

    A broken spring is very dangerous - the spring is no longer mounted correctly in the suspension and it cannot support the weight of the car, especially when cornering. The ride also suffers as the suspension is no longer able to absorb the bumps and impacts from the road. Aside from a visual inspection of the spring itself you might notice a clunking sound or banging noise coming from the front or rear. An inspection of the noise should also include other related items in the suspension: bushings, ball joints, links, mounts, etc. We also recommend replacing the rubber spring pads on the top and bottom of the spring because they lose their shape over time.

    The factory BMW springs sell for $200+ each. These are the same height as the stock replacement BMW springs which makes them a direct replacement.

    Sold only as a pair.

    This item fits the following BMWs:
    2004-2010 E83 BMW X3 2.5i X3 3.0i X3 3.0si
    NOT for cars with sport suspension

AST Suspension Lowering Springs are manufactured from a premium high tensile chromium-silicone wire which is handpicked by AST engineers for its quality and metal consistency. Each spring is cold wound and then heat treated to increase hardness and reduce internal stresses present after winding. Each spring is then individually shot peened, phosphate treated and then powder coated to outlast even the life of the vehicle.
