I got a killer deal on -30mm Eibach springs. So a long story short, do I have to get any other parts beside the springs?

lowering the car causes the rear toe arms to strech. The lower you go, the longer the rear arms need to be to reach the hub. My HR springs needed rear arms because the stock arms could not reach the hubs.
If you go even lower, you will need to do the same thing for the front, as well as lifting the stearing rack.
the only way to make the stock arms reach is to either really toe out, or decrease camber to zero or even +1.
I tried to be cheap, did the lowering myself, took it to porsche to align. They could not get it into specs and refused to do anything further. I said screw it I will drive it with correct camber but toe out.
I chewed up a new set of PS2, in 3 weeks of daily driving.
cost @ 450$
I got the cheap ebay arms, they where too fat, rubbed my rims.
then on the advise of the dealer, i got the tarret, fit great, alignment perfect, drives flat and nice, tires now last the standard 20K miles or so.

Amen to that:
I lowered with Eibach springs and was too cheap to get rear toe arms.
Ran through a set of new rear tires in 2,000 miles
Now with rear toe arms no unusual wear on the rear tires anymore

Performance cars are complex creatures!!
Change one thing, it effects several others........fix those, they effect several others, each..................... fix those...........
Ever wonder how Ferrari or McLaren can have dominating F1 cars for several years, each year being an update and development from each previous year and then next year, BAMM!! backmarker? They will sometimes make a change or innovation that effects so many other parts of the car, they can chase those changes for an entire year. Sometimes they have gone back to the previous year's car, while they try to sort stuff for next year!

This is something a lot of people don't understand when they modify their cars...
You think putting a stronger engine mount would help? Yeah really it does but it also make your car vibrate like no tomorrow!
There's always, always compromises...
Just ask me how I know this.

reading this thread makes me want to leave my suspension alone... I already have M030 as a factory option, but I've always wanted it just a BIT lower.....
maybe i'll just leave it..
