As your E30 ages, the rear differential bushing can crack, dry rot, and split. It's time for an upgrade. The ECS Tuning Heavy Duty Differential Bushing is crafted with performance in mind. Instead of using polyurethane, which is known for increasing NVH, the enthusiasts at ECS chose HD 70D rubber. This material offers a close-to-factory feel without the excess deflection of softer bushings, ensuring a pleasurable driving experience free from differential whine and excess movement.

Features & Benefits:

Eliminates Weak OEM Mount: The aging E30 chassis deserves an upgrade. Replace your old, cracked, and worn factory bushing with this HD alternative for improved performance. Perfect for Street or Track: Constructed from HD rubber instead of polyurethane or Delrin, this bushing provides comfort for daily driving while remaining effective in performance applications. Added Responsiveness: The 70D HD rubber compound is stiffer than the stock material, reducing drivetrain movement and effectively locking down your rear differential. Easy Installation: Precision-manufactured to the exact specifications of your OEM differential bushing, the ECS heavy-duty replacement installs just like the factory component. Whether you are replacing an aging factory bushing, removing excess driveline movement, or balancing performance and comfort, ECS Tuning has you covered with their Heavy Duty Rear Differential Bushing.

These rubber bushings from Meyle are a direct replacement for the stock differential bushings in the E46 3-series, E83 X3 SAV, and Z4 Roadster. If your original bushings are worn (likely around 100,000 miles) these are a great replacement upgrade. The front bushings are the stock OEM type rubber bushings. The rear bushing is a Meyle HD upgrade over stock - about 15% stiffer than the originals. This means the bushing will not flex and twist as much. This puts more power to the wheels since power is no longer used up for 'torquing' the bushing. These are not race bushings; the rubber material is perfectly suitable for street use.

The non-M E46/E83/Z4 models use three differential mounts - two front bushings in the subframe and one rear mount in the diff cover. This set of bushings covers all three. You can opt to include new mounting hardware in the Options list below.

This item fits the following BMWs:
1999-2005 E46 BMW 323i 323ci 325i 325ci 325xi 328i 328ci 330i 330ci 330xi

Your E36's rear differential is indirectly connected to your right foot through the engine and driveline, and connected to the seat of your pants through the chassis. Soft factory rubber differential bushings absorb vibrations between chassis and differential, providing comfort and softness in both of these connections. ECS Tuning's In-House Engineered Performance Polyurethane Differential Bushing eliminate deflection permitted by factory bushings, improving the connection you feel to your differential. Removal of this slop allows for crisper power transfer from differential to wheels, which means better throttle control while carving a canyon road, drag racing, sliding the rear end out, or just driving to work. This is achieved without the harshness or vibration associated with delrin or solid differential mounts. Featuring a tough 88A durometer polyurethane and Black anodized 6061-T6 aluminum Sleeve, our Performance Polyurethane Differential Bushings are more resistant to chemicals, ozone degradation, road salt, and general wear and tear than factory rubber bushings, resulting in a longer service life.

VTT noticed a hole in the F9X X3/4M market for a high-quality, lightweight, NVH-friendly, and easy-to-install Diff Lock Down kit to improve diff stability under launching, and hard cornering. So we did something about it and went to work on a very innovative design that 100% positively locks the diff down from movement, while shielding it from adding a ton of NVH, and can be used with the stock diff, and subframe bushings. This design uses existing mounting points on the vehicle, you do NOT have to remove the subframe or the Diff to install. Simply remove 4 differential bolts, drill two holes in the subframe slightly bigger, install two M8 riv-nuts, and install the lockdown, you do not even have to move the exhaust. A typical install can be 30-45 minutes for someone who is experienced working on vehicles, an hour or two if you like taking it slow. Features: Lightweight 1.5 lbs for the entire lockdown plate Uses FOUR connection points on the Diff, and three on the subframe for the ultimate in positive diff location, this will stop all diff movement on launch, saving your guibos, etc 100% Billet construction from 6061-T6 aluminum Anodized in 3 colors for corrosion resistance, a long-lasting finish, and good looks The subframe does NOT have to be removed for installation Uses all 12.9 grade hardware Does not add excessive NVH Positively locks down the diff to eliminate all unwanted movement under launches, acceleration, cornering, etc.

The E30 rear subframe is held into the chassis by two bolts going through these rubber mounts. A lot of suspension motion, chassis flex, and driveline torque has to go through these two points, which makes them notorious for failure. When they do, the subframe will move around, playing havoc with your suspension's alignment and settings and making a very annoying clunk. These are direct replacement rubber mounts, sold as a pair. This item fits the following BMWs: 1984-1991 E30 BMW 318i 318is 318ic 325e 325es 325i 325ic 325is M3
