Lambo gated shifters aren't all that to be honest., drive one, you'll see.

In your case, if you find the shifter requires too much effort, then you may want to invest in an extender. I know some ricer **** at CR with them, so asking around on there, may lead you to the seller.

Otherwise, I have a stock 5-speed shifter with the aluminum bushing. It takes a day or two to break in, but after that the shifting is pretty solid. I get some occasional notchy-ness, but its rare. The rest of the time, I get very solid decisive shifts out of it.

I think new fluid and filling the turret should help a lot also.

what about the metal shifter bushing I see for sale. I would've thought that was the main shifter seat bushing that would clean up the feel. Ive driven some spec cars with horrible shifting but I'm not going to spend 250 on a shifter. seems a little steep for this style of shift mechanism and its on back order anyway. well this will give me something to do after I finish all the big stuff.

The “Short” shifters that just make the top of the lever shorter bury the shif **** down in the console closer to the trans tunnel are completely retarded and just a stupid Idea.

For me the short throw shifters that alter the fulcrum and extend the shifter taller and closer to the steering wheel while maintaining a shortish throw are a worthwhile investment.

Never could shift the six speed with the accuracy of the five speed until I got the tall bent shifter from Miataroadster

http://www.miataroadster.com/miataro...s/g-63251.aspx

Super well presision made, double bushed pins, and proper ergonomic design. I love it on the track. The improvement over stock is very significant. the closer proximity of the **** to the steering wheel allows for qiicker shifts and better control of the car overall while shifting. Better for those corners that put you in a situation where you have to shift while cornering.

For the five speeds there are some cheap ebay ones that work pretty well.

The metal 6-speed stuff from Mazadaspeed is nice in my track car, but that trans has never shifted well.

The longer the fulcrum arm the more force applied at the other end(connected to tranny) with less effort. Go take some high school physics
I don't care how much longer you make the throw on the shifter and how much more leverage you put on it, it's not going to make the shifter feel any different. If it would, we'd all like 6-speeds more than we do. Ryan G went with a shorter throw, so high school physics tells you it takes more force to engage the gears because he reduced the lever ratio.

really the shifting is pretty good, I just dont like the feel of this shifter, it is smooth, just the throw is too short. it just makes me nervous for driving on the track, having to think about every shift is not my idea of a good time.

I'd pay a lot of money for a conversion set-up like that on a Miata.

Most people are effectively retarded...and yes, you're in that group.

I have it. It has transformed the way my 6speed shifts. 2nd gear crunch is completely gone except for initial stone-cold startup shifts, and even then it's less than it was previously warmed up. Reverse is easier to engage. The tall angled shifter is closer to the wheel and easier to reach. The gears are easier to find, and every shift is smoother than it was before.

And my stock shifter had new boots; it wasn't a torn boot contributing to the poor shifting feel.

The Aisin's may not have the overall internal build quality that the 5speeds do. The MR short shifter is definitely a better unit than stock, and definitely shifts better. End of story.
"Crunch" noises aren't from the shifter, the noises are a symptom of gear engagement. I've driven a car with the MR shifter on a 6-speed a few years ago. BellWilliam is not talking about the boot, he's talking about the plastic bits inside the neck, on the shifter mechanism. They wear out and should be replaced with the metal Mazdaspeed pieces.

Ever driven an S197 GT500? OMFG, that car will make you appreciate the Miata 6-speed. You never know when the gear engage, the throw is enormous, and it's a guessing game on gear selection. You really never feel anything engage, just a visual confirmation that you're in the desired gear, or you've run out of throw on the shifter.

C's get degrees.......

I would draw you a damn picture but I really dont give a $hit if you dont understand. It's obvious you have no engineering background what-so-ever.

Thowing out some arbitrary numbers here. If the top of the stock shifter is 8" from the fulcrum(moment) and the the bottom arm is 3" and say it takes 10 lbs of force to shift into gear.

After some math that comes to about 9Nm for the moment(of the fulcrum) and 29lbs of force on the bottom arm tip to the tranny.

Now, lets make a short shifter so lets legenthen the top of the shifter to 12" from the fulcrum and shorten the bottom to 2".

So with the new measurements of the SS it only takes 6.5Nm to shift into gear given the forces into the tranny are the same. With that moment the force on the top of the shifter is down to only 4.85 lbs of force.

Cliff notes:
Huster(retard) will not understand this
You can effectivly shorten throw and extend the shifter while lessening effort to go into gear.

Edit:

Math for everyone

10lb(44.5N)x8"(.2m)=9Nm

9Nm/.07m(3")=129N(29lb)

129N929lb)x2"(.05m)= 6.5Nm

6.5Nm/.3m(12")= 21.67N(4.85lb)

C's get degrees that get them management jobs at Starbucks. It's pretty clear you have a background of engineering shitty solutions since your solution didn't solve the original problem of shortening the throw.

Can you please explain how the 12"-2" lever provides a shorter throw on the 12" side than the 8"-3" lever on the 8" side?

tl;dr
You can't get the same work out if you put less work in.

Stock everything with a ebay "Delrin" (nylon) shift ****. We make sure bushings are fresh and preloaded. Mazda parts book has a numbers for shims to preload the main cup bushings. Been running Amsoil MTG but also testing Redline heavy shockproof gear oil in the 6 speeds trying to make the shift forks last longer.

This is relative to my interests. Although I liked the MTG, I can feel it "get thin" after the first couple laps and I basically have to shift without the clutch after that, where depressing the clutch pedal is more of a formality.

I guess with 200-hours on that trans I can't complain.

lol @ more work at a reduced ratio. I'm going to take my floor jack, take half the handle off, move the fulcrum in, and try to jack the car up. That should work with your analogy. If I'm getting Cs, you're fucked.

The SAABata will have nothing above the rubber boot on the tunnel so I'm going to try the shortie that came in the car. Likely I will leave the short shifter and and add an extension to the short shifter as I hear it is more positive than a stock shifter.

great this sounds promising. I can get a shifter for free/cheap from a friend who is parting several cars. so are you recommending the aluminum bushing or the plastic one? is there a procedure for setting the preload?

I'm a ricer *** with Said 2.75" shifter extender.

I also have an aluminum shifter bushing.

and a Stainless steel clutch line.

Buy this from me
