Is this the best of both worlds? Coilovers with adjustable ride height on the fly! Stanceparts cups. 

Can I get over that speed hump or into that underground carpark?

Every car enthusiast knows the pain of scraping that front lip getting in and out of driveways, or having anxiety about where you can and can't drive.
Thanks to the Stanceparts aircups, we no longer have that issue in our 900hp Supra project car :)
This video shows how they work, and what you need to do to install them.
These give a perfect combination between air-ride and track capable coil-overs. With air cup suspension you keep the ride quality and performance of your coil-overs and have the ability to raise your car with the push of a button. A great system for show, track, drift or daily driven cars.
The air cup lift system will fit on 90% of any brand coilovers. Your coilover must meet a certain dimensional requirement, otherwise the system will not fit.
It is basically an air cylinder on top of your coilover. Normally you will drive low, without the cups pressurised. Whenever you need to pass an obstacle, such as a speed bump or a driveway, you can apply pressure to the cups and it will raise your car around 50mm.
