start with taking this cover off!
next just loosen these nuts on the top of the strut assembly, do not take them all the way off!
next jack the car up and take the wheel off. this clamp is for the brake fluid line. loosen this assembly and let the line just hang.
now take these two bolts out that hold the strut assembly on to the bracket. these will be a little difficult if you are not using air tools. there should be little or no tension on the bolts they should slide right out.
next manuever the strut assembly around you axle so that it is not touching anything else especially your brake line. and then take the nuts off of the topside assembly and drop the spring and strut out.
if you do not have a spring compressor do not attempt this job. any local autoparts store will have a spring compressor that you can rent for like 40 dollars. clamp on the spring compressor and wrench them down evenly at 5 turns on one and 5 turns on the other and repeat the cycle until the spring is no longer touching the top of the perch pad. (which is the rubber peice that the spring is sitting on.
next take an allen wrench and hold while you loosen the nut on the top of the strut assembly. double check to see if there is any tension on the spring because if there is then this top cover peice will shoot off and that is dangerous. tighten the spring compressor more if needed. once the top nut is off you can slide the top peice off and take the spring off of the strut. pay close attention to how the factory spring sits in the holder and install the new spring the exact same way.
the new spring is shorter so you will not need the spring compressor to put the new springs back on. then you just put everything back on carefully and tighten in the reverse order that you loosened. that takes care of the front.
for the rear start by jacking the car up and taking off the wheel. take the lower shock absorber bolt out and set it aside.
now take the rear sway bar bottom connector link off, this requires another jack to jack up the rotor and lower control arm up until there is no tension on the sway bar link.
take off the brake line assembly so there is enough slack when you lower the second jack.
last take this bolt out and push down on the rotor and the spring should slide right out. thats it i hope you guys dont have any trouble with this it is very easy. and if you have questions just ask. these are tein s tech springs cost was 200 dollars and the ride quality is awesome. this car rides great now and will take corners like a champ. happy wrenching.
