1967 Buick Grand Sport 400 - Improve Your Car's Ride And Handling

The rear ride height sensors mount between the frame and lower control arms. Like the front sensors, they must be mounted so the lever is at midstroke when the rear suspension is 3 inches up from fully bottomed out.

The beautiful part is how the air compressor, reservoir tank, ECU, air feed valves, and solenoids are all permanently mounted to the self- contained Air Pod module. Just bolt it to the trunk floor over the rear axle, plumb it to the air feed lines running to each corner of the suspension, and you're good to go.

Ride height tuning is done by pushing buttons on the VFD (vacuum fluorescent display) control panel. You can store your three favorite ride heights and with the push of a button, toggle between them at will. Best of all, the remote control key fob controller (bottom) lets you adjust ride height settings from a distance. It's just like magic.

With the air springs fully pumped up, ride height is about an inch higher than stock. Rolling stock on this Buick GS consists of Boyds 17x8 front and 17x9.5 rear wheels with 4.25- and 5.50-inch backspacing, respectively. They're shod with Toyo Proxes T1R tires, size 265/40ZR17 rear, 255/45ZR17 front.

At the lowest setting, the body settles 6 inches for a bitchin' slammed-in-the-weeds look. Typical street and track operation is best with the ride set right in the middle. Of course, it is entirely up to you to make sure that your particular wheel and tire combination has sufficient body and frame clearance at all suspension settings and steering angles. On our Buick, the big 17-inch hoops were OK at the rear, but the front tires hit the front fender lips at the lowest settings, so that'd be purely for static display. As the stance increased, we got more full-lock front tire clearance but were only fully safe at maximum ride height. Adding 1/2 inch of front wheel backspacing and slightly smaller tires would solve these issues on our car. Yo, Gallagher, order up another set of front hoops!
