Has anyone with a 2005-2009 Mustang GT, running an automatic transmission, installed a "Street Fighter Ratchet Shifter"? I have been reading the information on the TCI website about this shifter, but it is pretty short. Not all of information listed, and I have not found any reviews yet from customers who have purchased this shifter.
Is it worth it? Does it make a considerable difference or improvement in performance? I have been told by some other car enthusiasts that it is simular to the "paddle shifter", or like the "slap" electronic shifter in the RS and RST cars. Is there any truth to this? Or is it just for looks?

Thanks,
