Also, lowering your car will require a wheel alignment which would then readjust any camber/toe offsets.

If the car is dropped too low, the new lower center of gravity of the car will prevent the camber from staying within factory specs. This is why camber plates and toe arms are sometimes necessary, unfortunately.

I don't know if the E60 camber will need adjustment ... really depends on how much you drop the car.? On most previous 5ers (e.g. E39) a drop of less than .75 inches generally did not affect the toe or camber.

[/quote]Thanks again to both. Yes, on the RX-7, the problem was that camber spec was breached and could not be restored without a kit. I sold the car years later having never added the available kit. You guys are helping me, and probably others, a huge amount, and I greatly appreciate the help.

that is incorrect. all you need a spring compressor to compress the spring and be able to put it back inside your shock. you can also go the extra mile and get new bump stops, but you really don't need them.

Yo man Hamann is H&R since they were used when he was racing.
They have a coilover system too it about 2000+16% VAT
the springs are about 300. not 700! 2-4 cms.
But the best is the coilover,
SG535d has Blistein check out the meet&greets Nurburgring!

The two most popular ways to lower a car is to 1) replace the stock springs with lowering springs and 2) replace the stock shock/springs combo with a complete coilover suspension.? Both are reversible...you would just reinstall the stock set up to get back to the original ride height.? There are actually cheaper methods such as cutting the springs or heating it to compress it, both of which would degrade the quality of the springs.
I believe H&R and Eibach make lowering springs for the e60 for probably less than $300.? ACS and Hamman are closer to $700 I think.? I'm not sure with the e60 but on other cars there are usually a sport and race option with sport having a lesser drop and more supple ride and race being lower and stiffer.?
Coilovers are complete springs and shocks units.? The body of the shocks are threaded and the spring sits on adjustable perches.? You can manually raise or lower the height by turning the spring seats with a wrench that comes with the coilover kit.? Coilovers will probably be around $1200 to $1500.
That's just my general knowledge of this topic.? I'm still curious as you to know if I'll need to lower my Sports Package equipped car when I get my 20" wheels or if that's not necessary.? And if I would need to roll the fenders.? Guess I'll find out this week when I get my rims installed.

[/quote]Compressing OEM springs to lower the car IMO is a really bad way to do it. And I don't mean "bad" in a good sense, either. Ride quality, spring life, shock compliance will all be out of whack.
Just my 0.02.

If you want to improve handling, then definately don't do springs without shocks. If you're interested in just looks, then I guess it'd be fine. Eibach makes springs that are supposed to work with stock shocks.
I've been researching coilovers for the m3, so not sure if this applies to the e60, but H&R along with PSS9s don't improve handling much over stock (e46 m3). If you're considering coilovers, I'd get a ground control kit, with spring rates customized to your needs. For the price, they're hard to beat.
