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.

Specs and Features:

• 7k Front & 14k Rear Spring Rate
• S-Barrel front & Linear rear springs
• Valved specifically to spring style and rate
• Camber Plate Front Mounts
• Aluminum and Rubber Rear Mounts
• Black Powder Coated Components
• All OE style brackets and mounting for perfect fit
• 30 Levels of Simultaneous Compression and Rebound Dampening
• 2 inch minimum and 3+ Inches of total potential drop
• Great for Track, Street, and any other conditions

• 52% stiffer than the factory E90/E92 M3 bar. 42% stiffer than the E93 M3 bar!
• 27mm straight across (not a tapered center like the E93 M3 factory bar)
• Solid core, not hollow like the stock bars (better at resisting twist)
• Forged, non-adjustable steel ends
• Highest tensile steel strength available

The H&R for the E9X M3 is the best anti-roll bar option for the E9X M3. Don't be let down by the "small" size compared to the factory sway bar sizes - there are some big differences! We've had our in-house suspension engineers run the math and the H&R swaybar is over 52% stiffer than the factory E90/E92 M3 bar and even over 42% stiffer than the E93 M3 sway bar upgrade. There are several reasons for this - the stock sway bars are hollow (for lighter weight) and will twist more than the solid H&R bar. Also, the E93 M3 bar is often called a 28mm bar but it actually tapers down in the center to 24mm which greatly reduces its effectiveness. So if you're looking for a serious sway bar upgrade, the H&R is clearly the way to go. Note: to maintain the handling balance of the car, we recommend only using the front bar with the matching H&R rear bar or heavily revised racing suspension.

When an E9X is lowered beyond the limits of just lowering springs, the rear wheels toe-in excessively. This excessive rear toe leads to premature wear, that many people attribute to an increase in negative camber. It has become a common belief that an extremely low vehicle will wear the tires wrong as a matter of consequence. It has become standard practice to go as low as you can and proceed to replace your tires every five to ten thousand miles. Whats more is that when the vehicle reaches a certain ride height, the factory arms become maxed out and there is no way to compensate and dial in the proper toe. You're left with an improperly aligned vehicle that is in effect worse off than it was with the stock suspension installed.

This is not only uneconomical but improper and unsafe. ECS Tuning is proud to offer a solution for this problem in the form of Rogue Engineering E9X adjustable rear toe arms. These arms allow for greater toe adjustment on vehicles that have been lowered with a coilover suspension. With the toe set properly the tires can contact the road properly this maximizes grip and minimizes wear. 

Features:

• 100% machined and anodized, 6061-T6 lightweight aluminum arms
• High-strength, 3-piece, rod end (with carbon fiber reinforced, PTFE race) offers longer life for street compared to standard rod ends
• SEALS-IT Rod end seals keep dirt, water, and other contaminants out
• Rod ends feature grease fittings, to allow for rod end serviceability.
• Lighter than stock!  (Stock is 875g, RE arms are 640g)
• Extremely easy installation and adjustment (your alignment shop will LOVE you!)

The same ride height as the standard H&R Sport springs but with a stiffer spring rate geared even more towards track performance. Fits all 2008+ E90 M3 sedan and E92 M3 coupe, with AND without electronic dampening control (EDC).

After thousands of street and track miles in our own 2008 M3 sedan project car (the white car pictured), we loved the way the "standard" H&R Sport Springs felt on both the street and track. Since the ride was so compliant on the street (even with 20" wheels), we felt some M3 owners might want to sacrifice some of the street ride quality for an even firmer spring rate that would handle even BETTER on the track. We asked, and H&R delivered -- and the H&R Sport PLUS springs for the E9x M3 were the answer. The same "ideal" ride height with a more aggressive spring rate that is still tolerable on the street (though not as forgiving as the standard H&R Sport springs) and more at home on the track.
