Air Lift's own description is as follows: "At Carolina Motorsports Park we loaded up 3 very different cars with 2 different suspensions and one very qualified third party driver. Our mission was to do back to back tests on statically lowered suspension, swap in Air Lift Performance suspension and hit the track again.
To test all aspects of the 2 different suspensions we performed three separate tests: a 200 ft skid pad, 100 ft slalom, and a 2.3 mile road course. We gathered all the data and figured up the averages of each run with each vehicle on the different suspensions. All that remains are the cold hard facts."
Take from it what you will - in any case, we're excited to see the outcome. Anyone else up for doing a comparison? What do you think of the results?
OUR VERIDICT
If you want a generally better experience from your car. Smoother ride, adjustable height at any time you want - GO FOR THE AIR
BUT if you are a true car enthusiast, for what you need to spend on a air system you can get some of the best coilovers money could buy ! Having said that the test shown by Air Lift is not very fair. By installing coils you will also have lots of fun tweaking and adjusting your car !
AIR is pretty popular right now especially for the people who only seek looks and stance but we would go for the old fashioned COILS.
