The air cups will fit any brand coilovers, as long as they meet the requirements.
Please follow the steps below before ordering.
Checking coilover clearance and springs
Make sure you have enough clearance around the coilovers, the air cups are 120mm in diameter, the fitting is 17mm. (110mm air cups available on request)
The air cups can only be installed on linear springs, it will not fit on ”shaped” springs as shown in the figure. In some situations shaped springs can be changed to linear springs.
Measure the thickest part of the shaft, we strongly recommend to measure with a caliper.
Air cups are available for coilover shaft diameters: 12,5mm, 14mm, 15mm, 16mm, 18mm, 20mm, 22mm, 40mm* and 45mm*
Maximum outer diameter: 99mm.
Minimum inner diameter: 61mm. (57mm on request)
In most cases the air cup will take between 20 and 30mm of height. The air cup itself is 20mm thick and with most coilovers the top hat comes on top of the air cup, this will take around 10mm. If there is enough thread left on the coilovers to lower the springs, it won’t be a problem. If not, you will need to install shorter springs.
The lift from the air cups comes from the droop / rebound of the coilovers. If you don’t have enough droop, the air cups simply can’t lift the full 50mm. If you’re using the standard spring rates that came with your coilovers, it should be fine. If you’re using higher spring rates we recommend to use helper springs to get the full lift.
WHAT IS DROOP?
Droop, also called rebound, is basically the amount of travel you have between ride height and full extension. Too much preload will decrease droop, we recommend to set a minimal preload. If you’re using extreme high spring rates, higher than the original rates that came with your coilovers, the weight of the car won’t compress the springs enough to create enough droop. This problem can be solved by installing helper springs, these will create enough droop for the air cups to lift.
The air cup lift system does not affect the ride quality and performance of your coilovers.The process of assembly is clearly described in the manual. Click here for an online view of the manual.
An air cup lift system is also known as air cup suspension, an air cup kit or a coilover lift system.
