BMW Suspension Parts for BMW E90 M3 S65 4.0L

Looking for coilovers that will provide reliability on street driven vehicles but are also capable of feeding your weekend track demon's desire for performance? BC Racing's BR Series coilover kit may be just the thing for you.

BR Series coilovers are the most popular and versatile option offered by BC racing, offering features such as 30-level dampening adjustment (simultaneous compression and rebound control), linear springs where possible, and a minimum of 2 inches ride height drop. To ensure performance, comfort, and quality, all BR Series kits are Dyno tested during the design stage to determine the best valving and spring rates, then installed and tested for a minimum of 6 months. This kit features mounts and brackets that are fully compatible with all stock mounting points and components.

The upper shock/strut mounts are all constructed of 6061-T6 Aluminum for strength and weight savings. BC Racing design 1 of 3 types of upper mounts for each vehicle: Caster/Camber Plates (+/- 3* camber), Camber Plates (+/- 3* camber), and Rubber Mount Plates (NVH reduction). The included mount option for this kit is shown in the kit specs and features below.

Lower shock mounts are powder coated for corrosion protection and constructed of either 6061-T6 aluminum that has been milled from a single piece (fork or bolt eye mount) or of STKM13C steel with all brackets welded robotically.

The included springs come in one of 3 styles: linear, S-barrel, and V-barrel. Linear springs are used in most applications unless limited by the OE design that does not allow the use of linear springs. All spring options are made from SAE9254 steel and have a zinc coating applied under the powder coating for increased spring corrosion protection and long term reliability.

All shock bodies used in the BR Series coilovers use a 53mm shock body (unless noted otherwise) for added strength, performance, and increased fluid capacity. All shocks are then powder coated black chrome for clean styling and corrosion protection.

• 7k Front & 14k Rear Spring Rate
• S-Barrel front & Linear rear springs
• Valved specifically to spring style and rate
• Camber Plate Front Mounts

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.

Features:

• DFV (Dual Flow Valve)
• Adjustable ride-height
• Fully rebuildable
• Corrosion salt spray tested (ISO 9227)
• Includes hardware and installation instructions
• 2 year Limited Warranty

Specs:

• Front Spring Rating: 343 lbs/in  ( 6 kg/mm)
• Rear Spring Rating: 686 lbs/in  ( 12 kg/mm)

*Now available are optional EDC Cancellation Modules that will prevent any lights or issues with suspension control systems. Turner Motorsport recommends purchasing these in addition to the suspension kit to get the most out of your Ohlins suspension system.
