i did this with my buddy like a week and a half ago on an ST185. I have not tried this on any other car but I'm sure it's probably very simliar anyways
Infact I'll post an indepth write up of it now, but i don't have pictures..
Things you'll need:
-5mm hex socket IS ABSOLUTELY ESSENTIAL HEX KEYS WILL NOT DO THE JOB AS THEY BEND WAY TOO EASILY
-12mm socket and a socket wrench
-12mm ratchet or wrench
-four 3/8" washers
Things that came with your whiteline swaybar
-yellow bushing, grease, D brackets and the swaybar itself
Steps to success
-ok, first thing you need to do is get your car up on jackstands and take off the wheels.
-next step is to locate the endlink that is connecting the strut to the swaybar.
-use the socket and socket wrench on the nut that connects the strut to the endlink to loosen the nut. this might take quite a bit of effort there is significant rust or if there's a lot of dirt wedging the bolt in place.
-After you loosen the nut take your ratchet or wrench and take a firm grip of the nut and then put the hex socket in the center. Have a friend hold one while you torque the nut off. This takes quite a bit of patience, and if your car hasn't had the endlinks touched in a while, make sure you use some cleaning agent to clean out the hex hole. This is not a part you want to strip and having dirt packed into that hole makes it so much easier to strip if you don't clean it out first.
-there is no tension on the strut pushing down on the swaybar when I had to do this, you may have to use a rubber mallet or something to push the bolt clear from the strut.
-Do the same for the other side
-now if you've done this part, the next few steps should be super easy in comparison. unbolt the d bracket and take off the old worn out bushings on either side. the sway bar is held by it's endlinks and bushings and if done correctly, the stock swaybar should be able to move freely only restricted by it's surroundings
-snake out the swaybar and TAKE NOTE OF HOW YOU THREADED IT OUT. I took it out from the right side of the car to the left. it's the same for both LHD/RHD. How I did it was i lifted the side of the sway bar up on the right side of the car, moved it towards the front of the car and pulled it out with the left end of the swaybar pointing towards the ground and just barely skimming the dush shield on the brake disc
-unbolt the endlinks AND MARK WHICH END IS WHICH, (i just marked the end that goes to the sway bar with a piece of chalk) from the stock swaybar you should now have these things:
new whiteline swaybar
-essentially you'll want to do everything in reverse so connect the endlinks back together with the new swaybar (remember we marked the end that connects to the swaybar?) and torque it enough so that it won't fly out.
-snake the swaybar back in the way you took it out. if i recall correctly, it goes over top of the diff and exhaust. I did this going from the left side of the car to the right. This is done before the bushings go back on because it's much less messy and much easier to get in without a piece of bushing constantly moving from side to side on the swaybar
-once you have it where it was supposed to go, grease up the yellow bushings and slip it on to where it was positioned on the stock swaybar. put the new washers where the stock bolts go and bolt the d brackets back into place.
once you've done this, rebolt the endlink to the strut and put your wheels back on!
