This advanced system empowers you to challenge your vehicle by independently adjusting rebound and low- and high-speed compression with a remote reservoir, providing distinct feedback and a unique driving sensation with each setting. ### Key Features: **Inverted Strut Design:** Built to withstand heavy side loads and braking forces, ensuring peak performance under intense conditions. **MONOTUBE Coilover Design:** Both front and rear dampers utilize this design, offering consistent performance and superior heat dissipation. **Adjustable Spring Rates:** Allows you to fine-tune your vehicle's suspension to meet your specific needs. **Rebound Adjustment:** With 12 distinct positions, you can control the damper's return to extension, affecting how the vehicle responds after compression and providing a unique driving experience with each setting. **Compression Adjustment:** Customize the suspension's response to compression with separate low- and high-speed controls: - **Low-Speed Compression:** Manages the suspension’s reaction to gentle, gradual forces. - **High-Speed Compression:** Handles rapid, forceful impacts. ### Benefits: - **Improved Handling:** Adjusting rebound and compression settings helps reduce body roll during cornering, enhancing responsiveness and maintaining tire contact for better traction. - **Customized Ride Comfort:** Fine-tune compression adjustments to balance performance and comfort, tailoring the ride quality to your preferences. - **Enhanced Front-End Grip:** Camber-adjustable front top mounts provide more wheel adjustment, transforming front-end grip and offering better control over your vehicle’s geometry. ### Additional Features: - **Solid Rear Top Mounts:** Ensure durability and stability under demanding conditions.

These are the best rear shock mounts that we have found for the E30, E36, E46, Z3 & E85 Z4! Featuring CNC-machined billet aluminum mounting base with a replaceable urethane bushing (replacement bushings are just $15 and are changed in minutes!). These mounts are excellent for either street or track because of their low NVH (noise, vibration, and harshness). Plus, the superior design will far outlast the life of stock mounts - maybe even the car itself. You'll never think twice about your shock mounts again! These shock mounts are a direct replacement of the stock mounts so they fit all shocks with the BMW-standard 10mm shock shaft, including all factory and OEM shocks (Boge, Sachs, etc), H&R coil overs, Bilstein shocks and PSS, PSS9, PSS10 coil overs (except the B16 Ride Control Kit). This is sold as a package with new shock mount gaskets, washers, and Nyloc nuts.

Must re-use factory cupped washers!

Any subframe work or reinforcement project on the rear of the E46 M3 should include a new set of subframe mounts. It's the worn rubber bushings that contribute to failed rear subframes on the E46 (but not the only reason). As the rubber gets worn, there is more flex to the mount. This flexing is then transferred to the sheetmetal in the floor where the spot welds will pop and the sheetmetal will crack. Additional force coming from stiffer suspensions and stickier tires will only increase the flexing of the mounts/chassis.

Of course, stiffer mounts would help prevent this problem but with a stiffer bushing comes ride harshness, vibration, and additional noise. Our engineers and technicians recommend replacement with the factory rubber bushings (along with the appropriate reinforcement of the floor). The rubber bushings help isolate bumps and impacts and are quiet. They are also a perfect fitment and require no maintenance.

This item is a set of 4 Original BMW rubber subframe mounts. Individual part numbers - 33 31 2 283 573 (left front), 33 31 2 283 574 (right front), and 33 31 2 283 419 (left and right rear, x 2).

Applications:
2001-2006 E46 M3, M3 CSL coupe, convertible

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
