Can someone please tell me what the standard rod length for the Height sensors on active suspension? Im trying to get mine setup correctly but am having trouble and cannot find the correct ( factory dialed) length. Say from locking nut to locking nut of one of the fronts and one of the rears.

Also , For some reason I come to a stop "say at traffic lights" and The active suspension likes to go up and down but not evenly... I dont know what has happened here but i cant figure it out. Any one have any ideas?

Also - If I wanted my car to go LOW eg see link... How would I do this?? Can I pull the active fuse out? If this would work I was hoping to run the fuse to a in cabin switch.zer...rkingI know this is a president but it should run the same setup correct?

Thanks and help would be appreciated.Lars

Once you get the height sensors set correctly then you should be able to readjust all 4 to be at a lower height in the OFF position. You're probably not going to get more than an inch though.

There's nothing wrong with lowering a Q but you need to be able to raise it up on demand BEFORE you hit that speed bump, parking barrier or pot hole. Without mentioning names, a lot of us remember the kid from NorCal who lowered his Q with no way to raise it and within a month took out the oil pan and fried the engine. Lucky for him it flipped off the tow truck on the freeway offramp and destroyed the car even more and he got top dollar ($3k?) from the tow's insurance company.

Measure the offset from the total length of suspension arm frame to hub, that will give you multiplication factor. For example if sensor attaches precisely to MIDPOINT then = 4x or 1/4" of shaft movement will equate to 1" of body position.

You are dealing with minute changes in dialing in the body..... a single turn is notable.
