What is air suspension?
Air suspension is exactly as it sounds: a system designed to cushion bumps in the road using air. The system utilises air bladders instead of coil springs, which can be inflated or deflated to adjust ride height with the touch of a button. Often seen in luxury cars, air ride offers unrivalled comfort, effectively ironing out the bumps and dips in the road.
Whether you want the comfort, or are aiming for the full ‘slammed’ look, air is the way to go. We stock kits and components from trusted manufacturers, for a wide range of makes and models. If you can’t find what you’re looking for, our friendly team is here to help. We also stock conventional coilover setups.

What is PCD?This relates to the 'stud pattern' of your wheels. For example, 4x100 means there are 4 studs per wheel, each 100mm apart. Information for specific makes and models is readily available online. Wheels you buy must have the same PCD as your car to fit.
-
What is a bore?This refers to the size of the hole in the centre of your wheel. The spigot (part of the hub) fits in this hole so that the wheels can support the car’s weight, and it’s essential that the bore (measured in mm) matches your spigot to prevent wheel wobble and imbalance. You can buy adaptors if your bore is too big. If it is too small, your wheel will not fit correctly.
-
What is offset?In simple terms this relates to how far a wheel sticks out. An offset of 0 means the centre of the wheel's width is in line with the mounting surface. Positive offset means the mounting point is in front of the wheel centre line, whereas negative offset means the mounting point is behind the centre. Generally speaking, the lower the number, the more the wheels will stick out.

How big can I go?Larger wheels may fill an arch better and allow for bigger brakes, but are often heavier and can impact fuel economy and handling. Smaller wheels are lighter, but may struggle to fit over brakes. You can check out forums and car clubs for your make or model for ideas. We recommend keeping the overall diameter (including the tyre) similar to what you have currently, to ensure the speedometer remains accurate.
