Right now I have only raced on the QM. In my 95 lude that I totalled last fall I ran a 15.57 and backed it up with a 15.59 for my best time. The 94 lude I have now is stock and I haven't ran the qm in it yet. I would love to do an autocross someday when i get all of my suspension done, but that wont happen until later in the summer.
