The BR Series hits the sweet spot between usability and performance.

Key Features

• 30-way adjustable damping (compression & rebound combined)

• Fully height adjustable via threaded shock body

Lowering an S550 Mustang the Right Way

The S550 chassis loves a controlled drop. It hates being slammed.

Recommended ride heights:

• 1.0–1.5 inches: Ideal for daily + spirited street use

• 1.5–2.0 inches: Aggressive stance / performance alignment

Go too low and you’ll:

• Kill suspension travel

• Increase bump steer

• Start blaming parts for geometry problems

BC Racing’s design allows height adjustment without sacrificing shock travel, which is why these actually drive well when lowered.

Ride Quality: Adjustable > Guesswork

With 30 damping clicks, you can tune the car instead of tolerating it.

• Softer settings → daily comfort, rough roads tolerated

• Middle settings → balanced performance street driving

• Stiffer settings → sharper response, reduced body roll

Compared to stock suspension:

• Less float at speed

• Better body control

• Improved confidence under braking and cornering

Firm when you want it. Civil when you don’t. Imagine that.

Alignment After Installation (Mandatory, Not Optional)

Lowering an S550 always changes alignment geometry.

What changes:

• Increased negative camber up front

• Toe shifts out of spec (tire killer #1)

• Caster affects straight-line stability and steering return

Strongly recommended:

• Professional alignment at final ride height

• Adjustable camber plates for proper correction

• Keep toe close to factory specs for street use

Good suspension with bad alignment is just expensive tire abuse.

Handling Improvements You’ll Feel Immediately

Once installed and aligned, expect:

• Sharper turn-in

• Reduced nose dive under braking

• Less body roll

• More mid-corner confidence

It won’t turn your Mustang into a GT3 car—but it will feel like Ford left performance on the table.

Build Quality & Ownership Notes

• High-quality materials and corrosion-resistant finishes

• Rebuildable monotube dampers

• Massive aftermarket support and parts availability

Install tip: Use anti-seize on threads and torque everything properly. Adjustable suspension rewards adults.
