Rear sway bar install complete! This tops my hardest install now followed by S2000 Super Charger Install. There were a lot of parts had to be removed for such a simple component. Also had to dealt with dropping subframe which I never had to do.
In my opinion, Cusco Install guide was very good as long as you could follow the pictures. there are few things I'd add to the manual.
1. All underside panels should be removed. pairs by exhaust, pairs on lower control arm, & pairs covering frame brace.
2. When lowering Exhaust, use hangers. See picture below.
I used wire hanger to hang the exhaust instead of dropping to floor. If you are completely detaching exhaust, this would not matter but I felt better to hang it.
3. Before fishing the old sway bar out, mark which side is left or right. I had to figure out for awhile to make sure which side i'm putting it in. It's like a puzzle that can only be solved once to take it out as well as putting new one in. you definitely don't want "oops, it's wrong side.." Especially if you are doing this by yourself, you need to go back and forth side to side to take it out and put new one in.
See below as a reference how much you need to lower the subframe.
It is about 4 inches and I was afraid that I was going to break wire but I just managed not to.
However... After attaching subframe and torqued to the spec, I found this...
passenger side spring did not wanted to stay in place.... I heard pop but didn't think of anything as it was getting late.. And found this spring assembly not in place...
So I called it a day... you may have noticed I even bought spring compressor... Don't bother with this on rear spring since this would not work with rear springs of Supra. After a good hot shower, I searched for spring installation on bmw/supra rear spring installation and gave me pretty good idea what I had to do.
Completed the installation today. Believe it or not at this stage, almost all mechanical parts were in its place. Just needed panels. After all that, no missing screws to nuts/bolts, nor left overs. Done some test drive to see if I have any code. No code, car drove just like before. Hard to see if it changed anything at the moment. I just need to wait 'til March.
