Guys,
I recently borrowed this tool from a guy who's a long-time member of the old Yahoo group. He has a website now where he rents and sells the tool. He made it and it's very nice. It makes removing the bushing relatively simple. You can do it with the subframe on the car. The site is
www.onetrack.ca. If you have any questions let me know. I used on my E30 but it also works on Z3s and the ti. The are some blurry pictures of the tool in action
here.
