I bought my car, and the guy was telligme that it had an HKS shortthrow. I looked at it, and it just has an HKS shift ****, and I cant find any labels or anything on the shifter, so I assumed he was either lying or ignorant. Oh well. But, I have a shift knowb from an STi that Ive had for years, and it fit both my FB and my freinds FC. I would assume that it would fit an FD, but either they dont or I have some kind of short shifter. I have no idea.

 

I think most Mazda's have the same thread pitch for the shifter. I bought a fairly generic GReddy **** that's supposed to fit most Mazdas and some other Japanese cars. Fits my FD great.

 

I took the rx-8 shift **** off my FD and it is now on my FC vert. So, yes

 

Well, WTF. My shifter is way too small, diameter wise, for the ****. I gotta figure out what shifter I have. Time for some pics I guess.

 

I believe the S5 ***** have the same thread as an FD, but the S4 are different.

 

^^^^ Correct.


The S4 (and most pre-1989 Mazda cars) had a 10m thread pitch, the S5 RX7 (and most post-1989 US Cars) have 8m thread pitch.


These numbers might be backwards, but you get the point!
