BC Racing BR Series Coilovers - Unleash the Ultimate Performance

BC Racing has earned its reputation among automotive enthusiasts by crafting adjustable coilover kits designed to excel on both the street and the track. With over a decade of experience, they offer performance solutions that are not only highly effective but also budget-friendly.

The BC Racing BR Series coilover suspension kit showcases versatile engineering with compatibility across all stock mounting locations and components. It stands as their most popular and adaptable suspension setup, featuring linear springs where feasible, 30 levels of dampening adjustment that covers both compression and rebound control, and a minimum 2-inch ride height drop. To ensure top-notch ride quality and reliability, all BR Series kits undergo rigorous dyno testing, including valving and spring rate assessments for each chassis.

Key components of the BC Racing coilover system are constructed with precision and durability in mind. Upper shock and strut mounts are made from lightweight yet robust 6061-T6 Aluminum. Front design options offer flexibility, with choices like Caster/Camber Plates, Camber plates, and Rubber Mount Plates, allowing for up to 3 degrees of camber adjustment. Rubber Mount Plates excel in reducing unwanted NVH (Noise, Vibration, Harshness).

Lower shock mounts come in two variations: either crafted from 6061-T6 Aluminum, like the upper mounts (Fork or Bolt Eye Style Mount), milled from a single piece, or made from high-quality STKM13C steel with robotic welding. Both styles are powder-coated to enhance corrosion protection and aesthetics.

BC Racing leaves no stone unturned when it comes to spring quality. They utilize SAE9254 steel for all springs, incorporating a Zinc coating beneath a powder-coated finish. This design ensures rust resistance, preserving spring performance and reliability. Linear springs are preferred wherever possible, but if the vehicle's original design limits their use, S-Barrel or V-Barrel springs are employed to match OE shape and style requirements. Spring rates are carefully matched to achieve the desired linear rate.

The heart of BC Racing's coilover kits is the shock assembly. They embrace a diverse range of shock types, lengths, and diameters, meticulously selected based on R&D data and the specificities of OEM suspension designs for different vehicle models. Every shock is meticulously hand-assembled and subjected to dyno testing for precise quality and performance. Shocks are paired based on their compression and rebound values to ensure even and reliable performance. The shock bodies feature a 53mm diameter, enhancing strength, performance, and fluid capacity, unless space constraints dictate otherwise. To top it all off, the shocks are treated with a black chrome finish for a clean, unified look and increased resistance to corrosion.

If you are concerned about strut tower mushrooming and looking for improved handling, the M7 Strut Tower Brace (STB) is the solution. This is the ONLY strut tower brace on the market that features anti-mushrooming technology.

Repeatedly, we've heard the same complaint: strut towers mushroom after heavy impacts from shocks and low aspect ratio tires. Initially, the shock towers take on a barely visible convex shape, but if compared to the original sheet metal, you'll find the horizontal plane has moved as much as 3/8" upwards, making alignment nearly impossible.

This issue often shows up as a slight pull to the left or right, depending on which strut tower is affected. The M7 Strut Tower Brace's end mounting plates solve this problem by sandwiching the sheet metal and shock top plate, creating a reinforced surface that won't bend, even during hard impacts.

The M7 STB features 1/2" (13mm) thick end plates that add extra strength to the strut towers, preventing mushrooming and potentially costly repairs. The cross brace significantly improves handling by adding torsional stiffness to the front body structure, helping keep your tires planted and pointed in the direction you want to go, especially during hard turns. Machined from billet aluminum and matte black powder coated, the M7 Strut Tower Brace boasts a durable black finish that looks great and won't chip or oxidize.

We have customers who won't drive their new MINI off the lot without one and dealers that sell every new MINI with either the M7 Strut Reinforcement Plates or the M7 Strut Tower Brace.

Concerned about clearance? No worries. The M7 STB profile is designed to clear both stock and aftermarket cold air intakes and ECUs. Its modular design allows easy access to the oil filter or any other accessories that might normally be blocked and require removal of the entire brace.

Installation is a snap (often taking less than 20 minutes)! No need for new nuts—the brace uses the three stock nuts on each side. Installation instructions are available online by clicking the "INSTALLATION" link on this page.

The M7 Strut Reinforcement Plates and the M7 Strut Tower Brace are two separate products that address strut tower mushrooming (you only need one or the other).

If your MINI is mainly a daily driver, the M7 Strut Reinforcement Plates are sufficient. If you have performance driving in mind, the M7 Strut Tower Brace is what you're looking for!

Please note:

• You cannot buy the SRPs and attach the cross-bar at a later time.
• The brace does not directly fit on the R50 and R52 Non-"S" Cooper due to limited hood clearance of the non-supercharged cars. It will fit but may push up on the hood slightly, requiring molding or cutting of the hood insulation after installation.
• Trimming of the underhood insulation material may be required to fully clear this brace. This is a very tight space.
