I have spent endless hours researching car lifts for my low ceiling garage (100") at a reasonable price. In addition, I completed a mega-analysis of forums dealing with different car manufactures. I stumbled upon a Porsche forum and found a person manufacturing liftbars for Porsche. I contacted Ken, at info@liftbars.com, who told me that he did not make liftbars for BMWs. I began working with him (actually only supplying him a few measurements) and he is now making custom liftbars for BMW. One type fits all 1 and 3 Series (1998-2012), another for the Z4, and one for Minis too. His prices are incredible. Using a low-profile hydraulic floor jack (lifting range from 2-5/8" to 23-3/4") and 6-ton jack stands, I am raising my Z4 close to 2' between my jack-points and floor. More than enough room for me to install brakes, rotate tires, and install a new exhaust system. His website with an animated GIF, contact, and price information is: http://bmw.liftbars.com
