Once you refitted the o/s shocker with self levelling h/lamp adjuster, did you have to adjust the sensor bar to allow for the car being lower? I had my Eibachs fitted last week and now the h/lamps dont adjust, they just point at the floor, not far in front of the carJust fited my springs today and you DO need to compress the front springs it is much easier.
The back ones i just took the 15mm bolt out of bottom arm, jacked the hub up and popped the old spring out, took about 5 mins.
Worth mentioning on the o/s front you also need to remove the self leveling h/lamp adjuster on the bottom arm,only an 8mm bolt but will get damaged if you try to remove the shocker with it still attached.
Also after fitting the springs and taking the car off the axl stands i had trouble getting my jack out(lol) because the car sat lower, but i am realy impressed with how the car sits, rides and looks.
