Ohlins Racing has a long history dating back to 1976 of providing premium motorcycle and automotive suspension systems to numerous racing teams, individual racers, and OE brands such as BMW Motorsport, Audi, Lamborghini. Pagani, Ducati and Kawasaki. Over time, thanks to extensive R&D, testing, and tuning, their products have evolved into some of the highest quality suspension systems in the world, providing years of flawless operation on both the street and the track.

Ohlins' latest automotive suspension system, the DFV (Dual Flow Valve) Road and Track Coilover Kit, has bridged the gap between comfortable stock suspension and track focused coilover kits. These kits provide a ride that glides over typical bumps and dips in the road, all without the typical hard rattle and harsh feel of usual coilovers, and turn in tight and maintain tire grip and traction in corners significantly better than stock suspension ever could. This is all thanks to the spring rate chosen and Ohlins and their signature Dual Flow Valve. The DFV maintains comfort and agility by giving the same characteristics for both rebound and compression, allowing the wheel and tire to maintain constant contact with the road/track for maximum control.

The Dual Flow Valve works by controlling shock fluid flow based on resistance and impact velocity. This is controlled in both compression and rebound, giving the quick shock operation that helps maintain traction. At low shaft travel speeds, oil flows mostly through the shaft jet bleed. At higher shaft speeds, oil flows mostly through the compression/rebound ports in the piston. At very high shaft speeds, or during sudden accelerations from potholes or large bumps in the road, oil can then escape through the ports in the DFV, absorbing a large amount of energy that would otherwise throw off the balance and control of the vehicle and keeping the tire planted firmly on the ground. With all three compression and rebound ports working together according to pressure and shaft speed, the result is the notorious premium suspension feel that only Ohlins can offer.

In addition to managing the rebound and compression control, coilovers must also properly address heat changes in the shock oil. As the shock is pushed harder and longer, the oil quickly heats up due to friction and compression, and the oils flow characteristics change. The hotter the oil is, the easier it is for it to travel through ports and valves. To prevent this typical fade in control, Ohlins has implemented a temperature controlled needle bleed valve system that will expand as temperatures rise, slowly increasing restriction in the fluids flow through the valve gap. This produces a consistent dampening rate that maintains the vehicle's suspension characteristics lap after lap, turn after turn, no matter how hard you push your suspension's capabilities.

BMW’s are known to have failure prone front thrust arm bushings.  The flexible rubber bushings, even those found in M performance models, allow significant movement of the front wheels to maximize daily driving comfort, but also allow considerable alignment change.  This results in a disconnected and numb road feel, standing between you and a confidence inspiring driving experience.  Eventually the fluid filled rubber bushings fatigue and crack due to continual deflection and ozone degradation, and eventually the damping fluid leaks out resulting in complete failure. 

For the enthusiast looking for superior performance and longevity with a crisp, confidence-inspiring driving experience, our sealed ball joint monoballs are the best solution available!  Our experience with spherical front control arm ball joints go back to those we designed and used in our IMSA E90 328i and E92 M3 racecars (GS class Champions in 2011).  We wanted to offer E31, E32, E34, E38, E39, E53, E60, E63, E64, and E83 owners similar levels of handling precision and control for the track and street. 

The bearing housing is precision CNC machined from 6061-T6 anodized aluminum and features a knurled OD to ensure a perfect press fit, and utilize a sealed OEM BMW ball joint for exceptional quality and durability, making them completely at home on both the street and track with no compromise.  We have done extensive street, autocross, and track testing to ensure the ball joint used in this bushing design excels in each setting.  The advantage of a sealed ball joint is that it eliminates all unwanted deflection while still allowing complete bind-free movement throughout suspension travel, resulting in exceptional control of wheel alignment.  What you get is superior steering precision, turn-in response, direct braking feedback, and better handling.

In short, if you're seeking the ultimate in precise, predictable handling and control, with crisp braking response and a long service life that’s equally at home on the street or track - look no further. We have you covered.

We offer these thrust arms with the monoball bushings pre-installed for your convenience. Since BMW recommends the control arms be replaced for every other bushing change, we prefer to sell these as a pre-assembled set. The bushings are also available separately if you wish to source your own control arms.

Features:

Bearing housing

• Precision CNC machined from 6061-T6 blue anodized aluminum
• Knurled OD to provide the perfect fit for the wide range of thrust arm bore diameters among brands.
• CNC machined 304ss ball joint sleeve inserts, providing a precision fit between the ball joint and the subframe. 

Bearing

• OEM BMW sealed and greased ball joint for exceptional durability and service life.

Performance

• Nearly instantaneous, crisp steering and braking response.
• Maintenance free, long lasting performance. 
• Improved road feel without undesirable NVH.

The rear lower control arms on E82/E9X models are the weakest link in the rear suspension. The arm is made from folded sheetmetal and it bends and deforms easily. Not only will it deform from potholes and curbs, tow truck drivers love to hook onto them without realizing how weak they are. We have seen other race teams complete the box section to make them stronger. A bent arm will throw off the geometry in the suspension, potentially affecting handling and tire wear. These aluminum arms are both lighter and stronger than the factory sheetmetal arms and is the best solution for chronic bending of the stock arm. These are a direct replacement to your stock arms with no changes needed to your alignment. New high-grade hardware is included.

Note: the stock arm is designed from the factory to be intentionally weak. These arms will bend so that something else in the suspension does not break. Our race cars used the stock sheetmetal arm but we replaced them often. We found that it was better to finish a race with a bent arm than not finish due to a catastrophic failure. The ECS arms are still designed to be the weakest link but are far stronger than the factory arm and will not bend as easily.

M3 upper and lower control arms are a known upgrade for non-M E82 and E9X chassis. But our Monoball Thurst Arms are even more of an upgrade over the stock M3 arms. This package bundles the Turner Monoball upper thrust arms with the stock M3 lower control arms. If there's one big fail point in the E82/E9X front suspension it's the thrust arms. The front inner thrust arm bushing is filled with dampening fluid that leaks over time. Once it's gone the bushing has the strength of a rubber band. Even though we sell two types of upgraded rubber bushings there was still room for improvement. For someone looking for superior performance and longevity these sealed monoball bushings are the best out there. 

The advantage of a monoball bearing is that it will not deflect under load. All of the rubber bushings, including the M3, move in all sorts of directions and that changes your alignment, especially when used with big brake kits or when driven hard. And when worn out, performance suffers. Our monoball sits in a CNC machined aluminum housing which has zero deflection. The monoball allows complete freedom of movement but only at the desired angles. What you get is superior steering precision, better handling from more consistent alignment, and almost infinite bushing life. And thanks to the inner liner and sealed rubber boots there's none of the extra noise or reduced service life of fully solid race bushings.

The lower M3 control arm bushings use a similar sealed monoball bushing instead of rubber. This package gives you monoball precision and performance with OE-quality components.

Fine-tuning your coilover damping shouldn’t mean stripping out your rear seats or interior panels. On many applications, rear shock adjusters are hidden behind carpet, trim, or seatbacks, making quick adjustments a hassle.

The ECS Rear Damping Extension Kit solves that problem with a clean and functional solution. These flexible extensions relocate the adjustment knobs to an easily accessible point above the rear shock towers, letting you dial in your suspension from inside the cabin, no disassembly required.

Installation is straightforward: simply drill a small access hole in your interior trim and route the extension cables through. The adjustment knobs can be removed to allow the line to pass through smaller openings, minimizing cutting. For proper installation, be sure to fully loosen the set screw, insert the cable, then securely tighten it using the provided Allen key.

Kit Includes:

(2) Rear damping adjuster extension cables
