saw this on ebay thought someone might want to pic it up(rx8 shifter cheap)
 

It's cheap but it's a 6 speed knob and it is falsely advertised that it will fit on any Mazda shifter. They only fit on rx8s, s5s and FDs.

no shit huh? I didn't know the s4 and s5 had differant threading? Crazy

Can u get an s5 shifter into an s4 tranny? You know..just for those s4 people who would one day like an rx-8 shifter ;)

yep

its going to suck when u go into 6 gear and its actually reverse.

Yes....that would suck.. :p:

ya i can imagine. when i was learning to drive i tried puting the car in reverse when it was rolling forward at like 2 MPH that scared the shit outa mee my dad thought that it was hilarious untill he remember we where in his car :D

Ya, but anything over 2 MPH and you are locked out of reverse. So shifting from 5 - reverse is impossible.

Now, I wonder if these are the "light-up" knobs, or if it is just a replica?

its impossible to downshift from 1st gear, but brittany spears did it in a ferrari...anything is possible.
