I'm a new member of the forum, and I have an unusual request: I want to learn about the Q45's active suspension (early- to mid-90s, I believe) for use in an entirely different car. I'm building a 1970 280SL which has all-1994 Corvette running gear. I want to replace the Corvette transverse leaf springs, which give a severe ride, and decided to do hydraulic suspension. Initially I thought of using the suspension from a late-70s 450SEL 6.9, but it's a crude setup compared with Infiniti's.

The curb weight will be about 3,000 pounds, so my first concern is whether the active suspension can adapt to a lighter car. Beyond that, is the system easily removed from the car, or are the electronics woven into the rest of the wiring harness? Is the active suspension controlled by a stand-alone computer? Is static level control achieved by hydraulic or electronic controls? Is compliance in the hydraulic system provided by sealed gas chambers?

From reading the postings, I read that TexasOil is the one to talk to about the active suspension. Is he available for consultation? Before I buy a parts car and remove the active suspension, I'd like to learn enough so I make the right choices.

I'd love to hear from as many of you as possible, to shed light on my zillion questions. Thanks in advance; you also may call me at 407/293-7030. -------Jim Rothrock

WHOA!!!

Damn, Jim! That's a hell of a project - Best of luck to you, keep us posted!!!

Thanks to Keith for his extensive help with sorting out the decision: Whether or not to use the Q45 system on the project car.

After reviewing the materials you sent to me, I realize that this would soon BECOME the project, so demanding and intricate an undertaking as it would be. So......I'll do the hydraulic suspension, but use the PASSIVE system employed on the 450SSEL 6.9, and subsequently, on the Euro 500SE/500SEL (available via the gray market here).

I'll keep you posted on the final result.

Peace,
