LOWERING SUSPENSION ON A E32 730ise

Ive just picked up a set of 17" BBS split rim, deep dish alloys with low profile tyres. The distance from the top of the front tyres to the arches looks alot more than it did with the 15" wheels on it?

Anyway, I have bought a set of lowering springs for the car to drop it by 50mm. The top of the rear tyres are almost level with the rear arches and it looks great, and there is about 52mm distance from the top of the tyre to the arch on both front wheels. I was going to just lower the front springs so the car sits at the same ride height all over....is it OK to just lower the front? Should I lower the whole car by 50mm??????

The rear shocks are fine as are the front struts.

Also, as haynes doesnt have a manual for this car, has anyone had the front springs out and could point out any areas that are particularly difficult? Ive done the springs on a few cars (82' Trans-Am, Volvo 760ect) so Im assuming that it will be roughly the same procedure to remove them? Any suggestions would be appreciated!

Oh forgot to mention........the 17" wheels I have, according to the BMW dealer, are only for a 5 series. BMW told me that 5 series alloys should not be used on a 7 series without a spigot adapter (or sleeve whatever you want to call it). Apparently the 5 series hub is slightsly smaller in diameter than the 7 series, so without the adapter the wheel isnt properly centered and you get vibration??? I would have though that the 5 studs would have centered the wheel, but I have to say that with the spigot adapters fitted, there isnt any vibration from the steering any more????! Nothing to do with the actuall post, but just thought Id pass on the info...you all probably know this already though!

LOS is an unknown quantity at this point
I have a repair manual for the 8 series... Both models are similar.
I'll see if there anything in particular that may apply to your question.

Try this website as well... HTTP://BIMMER.ROADFLY.COM
Click on message boards, then bmw message forum and then click on your model
There is a ton of good information. You may find the manual there, I did! (for the 8 series)
