Germanlook=$$$, your willing to spend 300 big ones on custom drilled drums, but not 400 on the struts to make the 17's work on your car
. Figure out what kind of 17's you want, maybe the Porsche stuff will work for you. The single pot 944 brake pieces aren't a lot and if you get the 2 bolt struts instead of three it will nearly be bolt-on. Just do a lil searching on ebay and wreckers. I don't know what your mech skill level is, but GL is advanced stuff.
Rear can be lowered for free with some patients and proper research. The biggest piece of advice is to do lots of research and figure out what you want to make of your super. There is a ton of other options out there then just the cheap CIP1 or jcw.com crap to mount on your vee dub.
Good luck
