BMW Suspension Parts for BMW 3 Series E30 (1984-1991)

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.

For vehicles with a 51mm front strut - Must be welded in to existing suspension

Bilstein has teamed up with Eibach to offer matched shock and spring packages. These Eibach springs are mated to a special set of Bilstein shocks to deliver a sporty and taut ride with as little impact on ride comfort as possible.

The Pro Kit uses an Eibach Pro Kit spring with Bilstein's Sport shocks and struts. Instead of taking parts from different manufacturers, Bilstein has tested the performance of the Eibach spring and tailored their shocks to be a true match for the new spring rate and ride height. This is known as a matched shock and spring and very few tuning companies take these extra steps. Eibach springs tend to be softer overall than most other aftermarket springs, which ensures the ride stays close to a stock comfort while still giving you a lowered stance and improved handling. 

Bilstein B12 Features: 

• Precise response and excellent driving performance
• Springs and shocks road tested and fine-tuned to complement one another
• Bilstein Monotube/Inverted gas pressure technology
• TUV certified
• Made In Germany
• Average Lowering of 25 to 40mm

Most cars don't need coil overs to improve their handling and bodyroll. For most drivers, simply replacing the shocks and springs with performance versions will meet their goals. If your shocks need replacing, and you felt the handling could be improved a little bit, this is an excellent performance suspension for you.

If E30 needs a little more pep in the corners, this is an excellent suspension package. H&R Sport springs and Bilstein Sport shocks for the E30 will lower the ride height for an aggressive stance and stiffer springs will improve handling and balance in the corners. This suspension is a favorite among our E30 fans because the car corners better without a punishing ride. Perfect for daily-driven E30s who want to carry more speed through the corners.

H&R Sport springs lower the ride height by 1.25" and stiffens the spring rate. Both combine to lower the car's center of gravity and reduce the amount of bodyroll in corners. The springs are progressive rate so their initial stiffness is actually very compliant and it becomes stiffer as the spring is compressed. This is great for street cars that see bumps and potholes where suspension compliance is key. Overall, they are about 40% stiffer than the stock original springs.

We use Bilstein Sport shocks as the dampers and they feature Bilstein's patented and innovative valving system. With this system, small bumps and impacts are absorbed as they should be. But the shocks stiffen for cornering and other suspension motions. It's the best of both worlds as the shock self-adjusts based on suspension motion. These fit with the stock strut and shock mounts, making for an easy and clean install.
 

Parts list:

• 1 set - H&R Sport Springs (50406)
• 1 pair - Bilstein Front Sport strut inserts (P36-0335 / 34-003350)
• 1 pair - Bilstein Rear Sport Shocks (B36-2027 / 24-020275)

Fitment note: Front strut inserts fit the larger 51mm strut housings. These were standard for all 6-cylinder E30s, all M3, and 1989-1992 318i/is. Other models used a smaller strut housing which requires a different Bilstein insert.
