Measured my W72's ride height, in preparation for the spring- and tire-replacement. As suspected, the rear is low.

Here are the numbers. Measurements in inches, taken with measuring tape off the floor passing through center cap more or less vertically up to the fender lip:
LeftRight
Front29.529.75
Rear28.2528.75

Not the most scientifically accurate measurement since I was pressed for time, but I tried to be consistent all the way through to get a good idea of whether my eyes were playing tricks on me. Sure enough, driver's rear is definitely the lowest of the bunch, and not evenly either.

Anyone know what the published specs are for stock WS6 ride height?

Once I know this info, I can set about planning the setup for my car... so far I'm pretty convinced of going with 255/60/15 for the rears but am considering 245/60/15 for the fronts depending on what springs I go for.
(and of course, I would like to keep WS6-like ride qualities due to our horrible roads up here)

just purchased a 78 ws6 ta with 62xxx miles.  It has a set of 245/60/15 bfg ta's on it and I like the look.  It does seem to sit a little low in the rear but I think thats normal for these cars.  I know 225/70/15 was the stock tire for a ws6, I figure this tire is OK to run on the car, it sure fills the wheel well nicely.  I want to insert a picture of the tire/rim but can't figure it out, how do you do it?
