hey luders,
I just got my Eibach Pro-kits installed yesterday. I thought i'd post my reaction since when i was deciding between springs, i could not find any. So hopefully this helps somebody out

. The drop is nice, not too low, but its not as low as i'd like it. My Greddy PE exhaust does not scrape, and i do not need to go over speed bumps diagonally. No bounce so far (on stock shocks), has an even drop, improved handling, and the steering wheel has no major alignment problems.
Installation:
First off all, get your hands on some food and maybe a heater. It was freezing cold when i was working on it. The fronts were relatively easy. I followed the instructions on ntpog.org. I had a few friends help me out, but most of the time only 2 people were working on 1 strut at a time. A spring compressor was handy. Make sure you use something like craftsman for your tools, i made the mistake of using taiwan made allen (spelling) wrench and it snapped on me. The rears were more difficult. The passenger side rear was way easier than the driver side rear, because the passenger side did not require a pittsman arm puller. Also, the driver side had the brake lines with interfered a lot!! The passanger side rear took 2 hours, and the driver side took 6 >_<. The driver side wheel had to be pushed down by 2 people in order to get the fork of the strut onto the arm. And..the freakin spring compressor froze on me when i was trying to loosen and take it out, so i had to cut it in 1/2. To me, i think if you do not have time and are not physically inclined, pay the $$ to get it installed by the pros.
total time: 10 hours

. estimated time from ntpog: ~2.5 hours
Ride and Look:
The ride is great so far. No bounce once so ever. I am riding on stock shocks until i can buy aftermarket. If i do straight onto a speed bump, slowly of course hehe, does not scrape anywhere. The Greddy PE supposidly hangs low, but with the pro-kits its perfect. The drop is even, 2 1/2 finger gap in front, 2 finger gap in rear. It looks good. This is how it should look off the factory. If i could choose again, however, i would have gotten different springs such as Eibach Sportlines or Neuspeed Race Springs, just for the lower drop. Maybe when i get some 17s, i might like the pro-kits more hehe.
Pics will be posted as soon as possible, whenever i can get my hand on a digi cam. sorry so long though, hope that helped somebody...happy luding.
