Product Description


Shifts are very smooth (almost too smooth, haha, I’m used to putting some force into it). NVH seems lower with the new insulation pieces.
- Kyle M.

After the installation, I drove around a little bit, everything feels great. I want to thank you for all your help.
- Phuon S.

The kit is well made and quite nice. Thanks!
- John B.

All I can say is wow!! This is the best mod you can do, bar none, if you have a 6 speed MX-5. The improvement is absolutely amazing – so, so impressed. Such a positive, crisp shift now. Extremely well-engineered.
- Rod E.

I usually don’t care for the way short shifters feel. They always feel vague and somewhat disconnected. Whatever you did is brilliant, it’s so direct. I’m just looking for opportunities just to change gears now. Excellently done, Sir!
- Erich W.

This kit is plain AWESOME! One of the best mods I’ve done.
- Todd C.

I’ve had one of Bill’s kits on every single Miata I’ve owned and I just bought ANOTHER one for my 6-speed car. Bill’s kits are complete, well thought out, and hands-down the best kit on the market that I’ve found. Bill is a damn good seller too, so I can’t recommend these enough. He’s great to work with and this shifter kit is on another level!
- Justin G.

Installed the 6-speed short throw shift kit in my Mazdaspeed. One of the best upgrades I have made to the car.  Easy install, great instructions, kit included EVERYTHING I needed.
- Peter F.

This shifter is a work of art, my friend!
- Brian G.

I had one of your fantastic short shifters in my Mazdaspeed Miata, then I purchased a 1999 5 speed. The 5-speed feels like shifting a truck compared to the throw on your short shifter.
- Andrew H.

I know what a Ferrari feels like after taking the Miata out last night with your short shifter. It’s amazing. I like the vibration, the crispness, the metallic sound, the heat, and of course the short shift.
- Jean L.

I can vouch for the quality of this product! Recently got one and anyone who drives my car can’t believe how good the shifter feels. I have a friend with a Porsche 964 and CAE short shifter and although it’s not 100% the same feeling, it’s really close. It made the transmission feel brand new again. Bill’s product is a great bang for the buck!
- Gil R.

Just came back from a run to test the shifter. It was all I’d heard claimed — like new only better. The only thing I was worried about was possible extra effort required because of the change in the leverage, but if there was, I didn’t notice it.
- Jack N.

I first heard about the MiataRoadster short shift kit after doing a bit of research online. I don’t buy anything without seeing some good reviews and my goodness, your shifter kit has rave reviews absolutely everywhere!
- Sam S.

LOVING it!!!!  What a transformation!
- Pete R.

This shifter is simply amazing. That is an understatement, but I can’t find the word to describe it. Installation was fairly simple and the shifter is well made. Everything is included in the kit. If you haven’t felt this shifter yet, you need to find someone who has used it. I highly recommend this kit.
- Anthony S.

Shifting the fulcrum means that a little more force is required to shift gears, but I actually like it better that way. I love the shorter throw — it’s definitely notched up the fun factor. The parts are beautifully made and assembly was a piece of cake — well done!
- Paul M.

We have one in our personal Mazdaspeed and this is will be the fourth one we’ve installed for a customer. Excellent product!
- Bob B.

LOVE LOVE LOVE this kit!! And you guys know I’m OCD about perfection. This kit IS perfection!!
- Randy G.

Wow! What a difference. The shifts are almost too short and precise. Totally impressed. My Miata went from “not sure what gear I’m shifting into,” to a precision instrument. On top of everything else, the darn thing is too pretty to hide under a shift boot.  It’s an outstanding addition to my 6-speed!
- Jeff E.

Your short shifter is my favorite one on the market. I have recommended it to many and installed a few as well. It’s a great product that works well.
- Ken H.

Just got time to fit my MX-5 6-speed shifter kit. Brilliant! Easy fit, well made, clear instructions, all good. It makes my NB8C’s 6-speed better than my NA8’s 5 speed!
- John F.

I received the shifter kit and installed it today and am very happy with it! The throw is very short compared to stock and I like it like that. Now it is fun to go through the gears when accelerating! Also with the stock shifter, if you have something plugged in the lighter, you scratch your hand on the connector going in 5th gear, but not anymore with the new shifter. It is not cheap, but the quality of your product is flawless.
- Max G.

Thank you for putting together such a well-engineered precision shift kit. This had to be a difficult task to improve something that didn’t leave much room to make any improvements. But then driving today I was really shocked you certainly did — and did by far. Everything about it all the way up 5 and down to 1 is just perfect and accurate with every throw. This shifter is worth every penny. Thank you and I will certainly speak highly of your product. Happy to have made my purchase.
- Sharon M.


As used in all of MiataRoadster’s sponsored race cars, my design is a true short shifter, with the fulcrum point relocated for better leverage and quicker shifts.

No more missed shifts, grinding gears, not being able to “find” the desired gear.

With a MiataRoadster shifter kit installed, any Miata transmission will be transformed.

You’ll fall in love all over again!

My unique tall/angled style shifter puts the knob 4” closer to the steering wheel so your hand can stay on the wheel more of the time during aggressive driving.

The shaft comes standard with a brushed finish. For $10 extra, I can have it polished to a mirror finish or powder coated (gloss black, matte black, wrinkle black or any other color of your choice).

Note for those with RHD (Right Hand Drive) cars: the shaft design is symmetrical, so it can rotated 180° and used in either LHD or RHD orientation.

Here’s my NA/NB Miata 5-speed and 6-speed installation manual.

Check out RevLimiter’s excellent illustrated installation manual (and rave review) of a 5-speed NA Miata kit. There are slight differences installing a kit in an NB Miata or FD. Email me if you need guidance.

Please don’t follow advice recommending using vice grips or pliers to move dowel pins in the stock turret. Doing so risks scratching the bore of the turret which will cause binding of the bushings on the shifter assembly.


We’ve determined that Mazda changed the design of the 6-speed transmission somewhere in between the 2001 and 2002 model years. So if you have a 2001-2002 6-speed, please check your VIN before ordering a shifter kit because the contents vary. If the last six digits of your VIN are below 220739, order the kit for 1999-2001. If the last six digits of your VIN are above 220738, order the kit for 2002-2005.


For NB2 6-speeds, Mazda enlarged the OD of the tip of the shaft (from 15mm to 17mm) and the ID of the hole in the turret (from 19mm to 21mm) vs. all NA/NB 5-speeds and NB1 6-speeds which share the smaller dimensions.

To complicate matters, all NB1/NB2 6-speed shafts have the same shorter distance between the axes of the fulcrum balls and tip balls vs. all NA/NB 5-speeds.

To economize on manufacturing our kits, MiataRoadster uses the same 15mm size tip on all shafts and uses proprietary thicker-walled bushings for NB2 6-speeds.

If you’re swapping a tranny, the VIN riveted onto the side of its case will confirm its source.

To the best of my knowledge, the breaking point between the Miata NB1 and NB2 6-speeds is the VIN ending in -220738. This should apply worldwide.
