Product details
Asphalt Rally Spec AR coilovers are set up for the 2006-2011 BMW 3 Series sedan, arriving as four assembled units sprung and valved for this application. Springs are 12 kg/mm in front and 14 kg/mm at the rear, so this setup stiffens the back end.
On many MacPherson applications an inverted shock keeps the gas and oil chamber away from the brakes and knuckle, which helps heat transfer and unsprung weight. The 55 mm body adds oil capacity and cooling under sustained loads. Every damper has one knob for 36 levels that change compression and rebound together.
Strengthened steel lower mounts are fitted on MacPherson applications, and ride height is set on the adjustable lower mount where the layout has one. Lock the collars with both spanner wrenches and have a professional complete the alignment. The kit is also listed for 2012-2013 BMW 3 Series models and for 2008-2011 BMW 1 Series RWD cars with 128i, 135i, 135is and cabrio bodies.
Supported features
Gravel Rally springs range from 250 mm to 270 mm with extended cylinder length and piston stroke, greatly improving handling over uneven and bumpy roads. Height range varies per vehicle and does not exceed OE ride height.
Asphalt Rally uses inverted shocks on many MacPherson applications, moving the gas/oil chamber away from the knuckle and brakes to reduce heat transfer and unsprung weight.
Strengthened steel lower mounts are standard on MacPherson applications; Gravel Rally adds heavy-duty steel upper mounts on most applications. Wishbone and multi-link applications use the standard aluminum mounts.
Gravel Rally kits use unique hardened-rubber pillowball top mounts on MacPherson applications to absorb repeated impacts from loose surfaces.
Simultaneous compression and rebound adjustment across 36 levels, with carefully selected per-application spring rates and damping to stabilize the car over uneven roads.
Inverted applications use 55 mm bodies for added oil capacity and cooling under sustained stage loads.

Installation
Set ride height with the adjustable lower mount where the application has one; use the spring perch only where the application-specific layout has no adjustable lower mount. Lock every collar with both spanner wrenches. Start damping 18 clicks counterclockwise from full stiff and adjust from there. Professional setup and alignment are required after installation; on MacPherson fronts, establish baseline camber at the elongated lower-mount hole before fine adjustment at the upper plate.
