Shift Knob Infoo

[BoxerRumbleSTi]

So my friend has a lathe and is making shift knobs. Asked me what the threads were in the subarus. So I did some research and did a write up since I was researching.
General Shift Knob Thread Fitments:

• Subaru manual = M12x1.25
• Subaru Automatic = M10x1.25

Subaru Shift Knob Car Fitments:

• 5-speed (WRX, RS, Forested, Legacy, etc): The shift knob must have the M12x1.25 thread inside. The shift knob can be for the STi and it will still work. The best type to get is one specifically designed to fit the WRX by having a boot lip on the bottom. The boot lip allows the shift boot to clip onto the knob so it doesn't dangle in the air.

• http://forums.nasioc.com/forums/showthread.php?t=1686647#6 Speed (STi & LGT Spec-B): The knob must be M12x1.25 threaded inside. The shift knob MUST have a counterbore on the bottom to allow for the Reverse Ring to slide into the knob. If the knob is just drilled out and threaded (without a counterbore), it may interfere with the reverse ring, not allowing it to pull up all the way. Or, the knob will just sit atop the shift lever, adding unnecessary height to the shifter. Also, many WRX knobs have a deep clearance hole drilled in them, so they won't even screw onto the STi shift lever.

• Automatic 4EAT (Impreza, Forester, Legacy, etc): All automatichttp://forums.nasioc.com/forums/showthread.php?t=1686647# knobs that are unscrewable must have an M10x1.25 internal thread. The lever is just a plain threaded rod, so basically any knob with this thread should fit onto it. Clearance must be designed into the knob so it doesn't touch the console (only if it is very tall).

Nice write up dude! I will never be wanting for shift knob info again. Takes all the guess work out of knob selection.

I'll make it a sticky once others have a chance to comment.

Sweet. Yeah like I was sayin, my buddy has a lathe and been doing some knobs. Just got done powder coating one of them. He had messaged me because in MY area Im like the subie guru. He was like dude, you know the threads for a subaru. Then I figured "hell, why not do a write up because I might need this if I need to fix my Kartboy knob since its stripped" haha. Then if anyone else needs it, then its here.
