• 12v 3-way valve
• Pre-wired 16mm LED switch
• Complete VIAIR compressor kit with 2 gallon tank. 
• Connecting material

Available in a range of sizes to suit various shaft diameters - This is the diameter of the damper shaft where the cup will sit and seal below the top spring cup.  


2 year warranty on the air cups.
1 year warranty on the compressor setup, covered by the manufacturer: VIAIR.
Where possible we always recommend using HSD or Driftworks Coilovers as we have extensive experience of this combination.

Please Note:
Air Cups are designed to raise the car over an obstacle and then return to standard ride height. They are not designed to be driven on for extended periods when fully inflated. This means you never lose the performance of your coilovers and won't be stranded if any part of the air system gets damaged.

If you're looking for a kit that allows you to drop your car low when parked and raises for driving see our grinds and maxload also d2racing kits  just click the imige

G1 By Grinds Handyapp module


Optional -

With the G1 additional module for smartphone control, we offer you the convenience of being able to control your vehicle from the outside.

The G1 APP module is simply inserted between the clinker connection on the valve block.

The app cannot be downloaded from the Apple store or Play store. A scan sheet is included in the package with every module order. This enables you to download.

Show off? Of course we say yes! Simply switch the ACC cable yellow to permanent and secure it with 5A fuse. The control panel in the car is therefore superfluous and you can use the app permanently.

Please be aware that with compressor operation ON, your battery will eventually drain of all voltage.


Warranty - Limited Lifetime warranty on the manifold. 1 year on other components.

Terms and conditions on the warranty are set out by Grinds Germany.


BR Series Street and Circuit Coilover

starting from £899.00+vat.

Price varies on make and model


  • Pillowball upper mount

  • Camber adjustable top mounts

  • Aluminium top plates

  • 30 way adjustable damping

  • Adjustable spring platform

  • Height adjustment via bottom mount to retain full damper travel

  • Bearing mounted upper front spring platform

  • Dust boot to protect damper seals

  • Some features are dependent on model


The BR series coil overs use a large 46mm diameter piston in a 53mm diameter damper body to maximise oil capacity.


As the damper unit operates the oil contained within heats up. The viscosity of oil changes as its temperature varies which can lead to changes in the damping characteristic of the unit.


BC Racing only use a very high quality oil with their coil overs but go that extra mile to maximise performance and build their BR range with a large 53mm diameter damper body. This increases the capacity of the unit which increases the volume of oil contained which in turn reduces the peak temperature and so significantly improves damper performance.


Corner weight adjustment:


The lower spring platform of the BC Racing coil overs are adjustable. This allows the car to be set up for corner weighting to achieve perfect balance and ensures that maximum tyre efficiency is achieved.


The car needs to be placing equal weight on each tyre on an axle so both front tyres need to be taking equal loading as do both rears. This makes sure that both tyres are doing their equal share of work when cornering which increases overall grip, maximises corner speed and reduces lap times.


Optional assister springs can be purchased to allow wheel droop to be dialled into the unit to suit specific needs.
