I have the "street" version
They both use the same mounting plate and mechanism. the difference is in the lever itself. The race has a one piece, short lever while the street re-uses the stock lever so it sits at stock height.
One advantage of the street and using the original lever is you do not have to disconnect the shift knob from it like you would for the race version (some people have had there knobs come loose after with the race).
People have also noted more vibration/noise with the rip shifter in general and more so with the race version but IDK, I think my street version is just as smooth and quiet as the stock, and it is a HELL of a lot more precise than the POS stock
Check out the picture in this thread
Ok, I am confused.... it shows the race version. (and why the B&M shifter sucks so baaad) the street is cut off with a mounting plate for the stock shifter (hard to explain exactly so...)
