View Full Version : Air Lift Performance Suspension Review

Mods hopefully you don't mind that this copy is a lift from my site but I am not typing this out again.

On the way back from H2O the odometer on my 2004 Mazda 3 clicked past 216,000 which means that I have now traveled roughly sixteen thousand kilometers on my Air Lift Performance suspension set-up.

Since my switch to the ‘darkside’ via the final production prototype of Air Lift’s Mazda 3 kit I’ve been repeatedly asked a few of the same questions about my suspension.

These questions are generally variations of: how does it ride, how reliable/accurate is the management system, and do you plan on driving it in the winter?

http://www.stanceiseverything.com/wp-content/uploads/2013/11/airlift_mazda3_review_5.jpg

To answer the last question first yes I will continue to drive my car all year. This car is, and will always be, a daily driver and that includes driving it straight through the absolute worst of the winter conditions here in Toronto.

My immediate plans for winter prep are actually quite simple; drain the tank more often.

Air Lift tests their bags and struts to both hot and cold extremes so I’ve got nothing to worry about in that regard, and since the main issues people have running air in the winter stems from moisture freezing in the lines –or leaks of which I have none– draining my tank weekly instead of monthly should eliminate/minimize any problems I could encounter.

http://www.stanceiseverything.com/wp-content/uploads/2013/11/airlift_mazda3_review_10.jpg

Should the aforementioned not be sufficient I will add a little brake line antifreeze to the mix, if I encounter any problems after that step I will add a water trap.

I intend to do a mid winter update on this very subject so if you are particularly concerned about winter driving on bags look out for that post in February.

In terms of reliability my set-up has thus far been absolutely rock solid. The Autopilot V2 management system really is quite the small wonder, it occupies next to no space in my hatch and performs flawlessly.

Currently I have four ride height presets, an all up, and an all down saved in my V2.

My presets (measured in psi) are as follows (FL, FR, RL, RR)

Solo
38
38
38
30


One Passenger
40
42
38
35


Two Passengers
42
42
43
40


Three Passengers (full car)
43
43
52
49


All Up
70
70
65
65


All Down
0
0
0
0


These presets put me at roughly 22 3/4″ front and 23 1/4″ rear fender to ground which equates to a very minimal amount of tire tuck with a slight forward rake.

This is exactly how I wanted my car to sit and hair lower than I was static.

http://www.stanceiseverything.com/wp-content/uploads/2013/08/airlift_mazda3_review_1.jpg

One of the biggest advantages of the Air Lift strut set-up is that as the system raises or lowers psi in the air spring the spring rates increase or decrease respectively, while the struts maintain their full length of travel.

This means that the increase in pressure at each preset above ensures that my wheels don’t hit my fenders and the car doesn’t hit the ground over bumps when more passengers are introduced.

Determining the best pressures for the above scenarios only took about a minute or two of play on manual mode when faced with a new scenario. In fact my full car preset was established in a matter of minutes in Ocean City when we decided to cruise the strip in my car.

Should a new situation arise I still have three more presets to play with, which quite frankly is more than enough.

If you are curious about the difference in drivers rear versus passenger rear, my passenger quarter was the first one I ever rolled and has slightly more pull which means in order to look right visually I run a little less psi.

http://www.stanceiseverything.com/wp-content/uploads/2013/11/airlift_mazda_3_kit.jpg
http://www.stanceiseverything.com/wp-content/uploads/2013/11/airlift_mazda3_review_2.jpg

In my eight month experience the system has always come within +/- 1 psi of the preset and the only ‘problem’ I’ve ever encountered is the car not sitting quite as low as I want when transitioning to ride height from the all up preset.

The pressures read correct but the car for whatever reason it sits a little bit high. This could be attributed to the fact that whenever I use all up I also jack the car off the ground.

If I double tap the preset button with the car in motion things settle down back to where they should be. With the way my (and presumably most of you) wheels are set-up the system erring on the side of too high is easier on the wallet than too low.

The ride quality, in a word, is beautiful. While I managed to convince myself my static ride wasn’t that bad, my passengers thought quite the contrary. Previously I had next to no travel with moderately stiff springs, which meant anyone in my car felt every bump in the road and on occasion got to know the physical limits of my suspension travel quite intimately.

The improvement in ride quality was noticeable the instant I first drove the car on air and to date I have yet to bottom out my struts in the sixteen thousand km I’ve driven.

This includes trips to Detroit, Montreal, and Ocean City.

http://www.stanceiseverything.com/wp-content/uploads/2013/11/airlift_mazda3_review_3.jpg

Despite what many assume, modern air suspension is not ‘floaty’ or under damped, and the best way to describe my ride quality now would be to liken it to a functionally set up street coilover system.

My ride quality is now worlds away from stock, stiffer than springs, but considerably more enjoyable than your standard (BC/Stance/Megan/Raceland ETC) coilovers at full down and full stiff.

Set to 20/30 in the adjustment range I can feel at ease driving my parents around without fear of rattling their brains out, and my wife has gone as far to admit that the car is now comfortable to travel within.

At the same time I can take on/off ramps at a good clip and not have to worry about my wheels having it out with my quarter panels, or feeling like I am the captain of a particularly large sea vessel.

I've yet to take the car onto a track but I know that Air Lift did track test this suspension set-up and it performed quite well.


All said and done I honestly couldn't be happier with my car on air and can’t really think of any reason why I would switch back. The ride is firm but forgiving, the system can be counted on, the only thing I had to sacrifice was a spare tire, and I can park right on the ground.

Very nice.
Your lower psi ride heights (i'm 63/55/70/70) must make for a more comforable ride.

Great post! I always wondered about the winter thing. Makes me want air now, but hell, I haven't even gone springs yet haha.
What setup were you running before?

Glad you guys liked it. Decided to put sometime into it and most importantly do it with some KM on the car.

I was previously on BC coils with 10k 135mm springs up front. I had been on those BCs in different configurations for about three years. Prior to that sportlines.

You totally do ride lower static when I looked at your fender to ground when writing this I was like WTF.

I'm not sure I could run that low and not have something come into contact with something else.

Nice review on air lift. Makes me wanna get one too but need other stuff first.
Hows fast speed cornering on bags, like doing 80 on those nice smooth round on/off ramps. Any loss of traction or understeer.

It's good, comparable to my coils before I monkeyed with them. Bumps on ramps the car feels less skittish probably because I have travel.

The Air Lift kit also allows me to retain my rear sway bar, which is an after market one which helps.

isnt there more suspension travel with air? im shocked you ride that low!

You're bang on about the travel and proper damping. The stiffer coils would definitely be the culprit for the car getting upset over bumps while cornering hard.

There is for sure most travel but keep in mind I am less aggressive than you so over bumps I just tuck a little more tire and go about my business. I've never had the car hit the ground, liner rub occasionally which is what I had prior to the 10k springs.

Can you please post more photos of the rear arms. Do they have spherical bearings instead of bushings?

The pics of the different setups are great. I would love to have air, hopefully on the next car.

how has the suspension been holding up to the 'polar vortex' temps we've been having past few weeks?
you mentioned draining the tank more often, have you had to add the water trap and/or antifreeze?

Dave_The_BMXER
01-24-2014, 08:45 AM
Nope, I've not added anything. I admittedly don't play with the suspension when its -30 below just to avoid issues but anytime I have had to air up this winter it's been fine.

I used to have airlift slam x on my jetta GLI, but compare to coils it's way too soft
Don't know how's the performance one does

Dave_The_BMXER

So far they have been stiff enough to keep me from getting in trouble. :)

are they still like the old one? More lower more softer?

Dave_The_BMXER
01-31-2014, 01:28 PM
Yes the less psi the lower the spring rate, this is true of all air systems. However I'm not sure which version of the Slam XLs you had but they now have adjustable dampening (like mine) so if it wasn't to your liking you could firm it up that way.

viewed the airlift performance kit vs coilover video at Vimeo. Airlift does good job, I might gonna try one on my GTI
Love the kit coming with camber plate

Not slightly jelly, definitely jelly, I'd love to install air lift into my car but I don't think they make a specific set for the 2013 3's :(

REALLY?! the 04-09 kit will fit? I thought it was different.

It will fit. You might need a longer rear shock bolt, but you need that with coils too.

04-09 kit from Air Rex has been installed on at least 4 second gen cars now, no reason to expect the Air Lift one is different.

Do you know the exact specs for the bolt?

Dave_The_BMXER
02-02-2014, 10:11 PM
Yeah it's the same kit. I told them that it was. However they are extremely particular about what cars they will list their product for. For example it fits the Volvo C30 as well but they wouldn't list it as such until they personally did the install and made sure no issues were found.

You go to mazda and ask for the 04-09 rear strut lower bolt.
