Here ya go...I did up a short video, as it's probably easier to explain in words with the tool in front of me:
The only thing you may have issue with is getting the RTA up to ride height with the car off the ground. If it's an issue, unbolt the sway bar and you should be able to get there. You can always just remove the spring as well, which only takes a second. Make sure the e-brake isn't engaged.
Hope that helps.
Looking to buy a base E30 3'er coupe in or near CT. PM me if you're selling.
