Why air suspension is mandatory on old full-size cruisers if you actually want to use them.

My 1964 Bonneville is a huge land barge (hence the name of this website) that I am rebuilding into a car that will cruise the streets and highways with ease. It isn’t a tyre-frying muscle car built to slay drag strips, or go drifting, or even win trophies for Shiniest Undercarriage Painted In 2pack at shows.

This meant, in my mind, I wanted air suspension for its adjustability, to help make access to driveways and carparks easier, and to look absolutely awesome when parked. My car came with an older, very basic air system that I have reconfigured (see HERE) but I thought it would be good to give a practical demonstration as to why air suspension works better on this car, than coil springs.

When I first imported my car this was the maximum height it could achieve. Unbelievably it still dragged its rear-end getting on and off tow trucks!


Generally, when “Pontiac people” see THIS photo they they flip out and tell me I have wrecked the car and turned it into some ghetto sled. Personally, I love the slammed look when it is parked but the world is a diverse place with a heap of opinions from people who disagree with me (who I am free to ignore).


I had to fit 17-inch American Racing 200S wheels to my car to clear the new Master Power disc brake system. This gives a good look at how my car tucks its wheels when aired out now. Ryan at United Speed Shop also relocated the front shock absorbers to the chassis in front of the wheels to get them out of the engine bay.


Sitting at ride height (below) it retains legal ride height for Australia, which means a minimum of 100mm ground clearance. I think it will look great driving down the road and the Accuair E-level system will keep the car level and at this height even when fully loaded. No spring sag or lop-sided ride here!


When it comes time to load the big Bonne up onto a tow truck, access a steep driveway or climb over some speedhumps there won’t be any grinding noises from underneath. Check the “access height” – the tallest the Accuair system can lift the car to.


And then when it parks, down she goes for the “cool” stance.


Aired out the car looks far more like how the Bonnevilles were drawn in Pontiac ads of the time – long, low and wide (and what made me fall in love with this model!)
