I am looking at the jack-be-quick as well for my 2012 Roadster that I just picked up. I sent an email to the company with some questions I had and this is the response I got back from them:
"Hi Matt, thanks for your interest. The front and rear or the rear alone of the R3 can be lifted with the one bracket, depending on the placement of the jack. The JBQ for R3 if so mounted just aft of the center of balance. If the left rail is placed under the JBQ you will lift both wheels. If the right rail is, you will lift the back wheel only. There is also an available bracket for the front if you want to lift the front by itself, but we may need to talk about that as there have been some fitment issues with some equipment.
Bob @ JBQ"
Maybe I am being dense (wouldn't be the first time) but I am not picturing all of this. If you want to raise both tires up in the air and you put the left rail of the lift under the bracket to lift up both tires, then where is the right rail going under? There is only one bracket being sold so is the right rail of my lift going up under the casings? Also, with this system do you have to take the brackets off when you want to do an oil change and drain the sump? Thank you for the help!
