All four corners r281. I'm just gonna' go with Eibach 1-1/2" springs. I've talked to a few people now and I don't like the idea of PLANNING the navigation of speedbumps, driveways, potholes, etc. Thanks for the info. In theory, your husband is right...but it doesn't work by gravity and car attitude alone. Too bad though. That would be easy and free. Lower the pressure in the rears and you've lowered the rear of the car AND increased the grip of the tires. Been done for a hundred years...ask me how I know.
Anyway, thanks again for sharing his experiences!
