Shift Mechanism Modification

[Slickvic]

]Hey guys, i am not that great on forums so i wanted to ask you all for help.

i have a 2007 true red mazdaspeed3

i was looking if there is any thread that might mention the Pitch and Diameter of the shifter Shaft, the silver stick that the shift knob screws into to.

i want to find a dial Machinery piece) that could be screwed on the shaft and create more and longer grooves , after doing so i will be taking out the washer that holds the shift boot in place and cut the shaft about one inch so i would have a shorter shaft. (just personal preference, for me it is a little bit more comfortable having it sit lower)

im aware that sell this type of shift linkage but im on a very tight budget and i have a friend that works in a shop and has access to all these tool so i fig i would make it myself but to help him help me, i need to find the these numbers.

do so, and do so properly, i want to find the pitch of the existing groove (i think that is what its called) and the diameter of the stick so i can cut and make it properly.

i have one worry though... where the stock washer is in place, it seems that the diameter of the shaft gets a tiny bit bigger.... would anyone know about those diameters too?

i kno this is kinda a hard request but i feel that if we kno this information we might get some other cool modifications to stock shift linkage without spending too much money.

i tried calling mazda dealerships and nothing. i been trying to get a hold of mazda corporation itself but i cant get a hold of them.

i have the tech manual for my car, i will be looking for it in there too but i dont think they have it.

if the information already exist then i apologize for the rant, i wasn't able to find it. (gah)

Thanks in advance

Not meaning to be a smart-ass at all, but if your friend works in a shop, couldn't he just take the measurements if you drive the car to the shop? I would think they have the proper tools.

Beyond that, I might call TWM Performance, a sponsor of these forums. They make a popular short shifter, and probably know the numbers you need. Might be a little odd to call a company & ask them for help in not purchasing their product, but worth a shot.

Why hassle with all that. Get a short shift plate from JBarone and a weighted knob from E4 Performance.

I believe he wants to actually lower the shifter.

hmm. so i haven't been around for a while. is the plate what everyone is doing instead of shifters now? i still have my old TWM unit installed, but i knew someone would come up with this since most cable actuated transmissions have always required just some sort of adapter for shortening the throw, instead of a new stick assembly. my 8th gen si has a little adapter that was made by comptech before they went out of business.

I'll lend a helping hand here because I've been working with Vic on this project.

What he is trying to do is shorten the height of the stock shift lever. Because he is doing this on a tight budget, buying the aftermarket TWM shifter is not an option, so, he is trying to modify the existing shift lever.

The problem is the z-bend that is in the shift arm from the factory. Because of this z-bend, it's not possible to simply use a die and add threads to the existing shift lever. He already has my J-Speed SSP shift plate so his shift throws are shorter than factory.

For those who are interested, the thread pitch and diameter of the stock shift lever is M10x1.25.
