TBH I've never fitted air ride, I've always gone with coil overs on previous toys and either had the cars lowered and mostly ended up bashing the heck out the front, or had them higher that I might as well have stuck with stock. Airlift isn't cheap either so if I end up making the wrong choice it's the thick end of £5,000. A set of Tein Flex Zs are >£1000.
