First off, never assume spring rates just because of the BMW model. Just because you have a 740 does not mean it has a higher spring rate than a 735 for the rears.

Bimmerd00d has actually been with the community since roadflea.

Anyways, I understand what Bimmerd00d is asking. He is using his wagon as a daily driver for point A to point B. Spring rates don't necessarily mean the car height will raise. I have done over 2 dozen sets of suspension on e34s and various combinations of springs and shocks. Years ago I did catalog the spring rates and spring numbers, but that was 2 computers ago and I don't have my spreadsheets.

I guess what Bimmerd00d is looking for is just a cheaper alternative to the rear. Oh, there is a $10 solution to the handle the sls as I have done it on 2 M5s and 2 wagons. All US wagons came with sls, but not all Euro wagons came with sls. The correct way to set the height is to use Euro wagon springs. That will give the correct height as well as correct spring rate. Now, if you don't care as much about the spring rate, then go ahead and play with the springs. A stock sedan spring along with the added rear weight of the wagon will in affect lower the stock height of that spring, thus better matching the height of your front B&G springs.

As far as the height and matching, there is the static height, then the suspension travel variance in motion. So, static height should be good, but my only concern is when the car moves, tucks on acceleration, and handling bumps. The matching of the spring height, rate, strut travel and strut compression and rebound settings can affect your ride. As long as you just use the touring from point A to point B as a daily driver, then I am assuming this isn't as much of a concern. Plus, your roads in Texas are pretty good roads. If it were me, I would find matching sets, but that's because it is me. My roads here in Chicago need more balanced and compliant suspension, even for daily driving.

Hope that helps. Either way, good luck with your venture.
Ahh now this is how these posts should go, informative without all the BS. I was thinking of going the euro 525iT sport spring route. If i can get ahold of a pair, i'll just get the full set of 4 and be done with it. The E32 springs are just super easy to find around here, hence the reason for this thread.
