I'd love to say Mazda did it to balance the car with just a driver, and they may have, but my Tundra has a similarly angled driveshaft for some reason. It creates a vibration at certain speeds.

By pure dumb luck we ended up just off zero for the drive shaft angle and right at zero for the included angle. We're going to measure once it's all mocked up again to make sure our DS is not exactly at zero.
On a related note for anyone with mysterious driveline vibrations, set your PPF height according to the FSM and compensate for crunched frames rails (they're the reference).

So we learned something interesting about the NA/NB while measuring our final driveshaft position. Our target parallel angle was 1° which is where we are. While measuring it, we noticed the OEM NA/NB driveshaft angle is 1° laterally. Looking forward form diff, the shaft angles towards pax side just a bit. Not sure if the diff mounts are angled, or the diff casting is asymetric. Looks like the OEM shaft is actually 0° vertically but right at the ideal 1° laterally. We ended up with that same lateral offset as well.
So when is the SuperMiata Version of the Quaife Conversion kit going to be come available. Just blew up my first 6 speed for the year. Made for a very short Track day last weekend. I Have 5 more
thankfully. I should'nt be to upset, it lasted a full year.

Haha, never. The number of worldwide Miata owners willing to spend $12k on a transmission kit can be counted on one hand. Beyond that there is no margin whatsoever. Not a small margin, no margin. If you are one of the folks with that kind of budget, I would suggest contacting Hitech in Irvine for a duplicate of the mounts they made for us.

Offering a "kit" makes zero sense from a business POV. Emilio was kind enough to share his journey so followers like myself are not going in blind. Props E!

Which Geartronics gear **** load cell did you get? The line one? Geartronics - Sequential gearbox electronic systems - Flatshift Pro . Where did you install it? The geartronics paddleshift system seems heavily overpriced but I suppose it is a niche market.

Emilio, which lever type did you choose? QGE60G00X where X denotes lever type.

The lever shown in the picture. It is also in the bill of materials for the Miata kit, not sure what the part number is. I contacted geartronics and asked them to send me a shift **** with the correct thread for the lever. That is all I purchased from them, we are not using their Electronics.
When I clicked through on their page previously, I didn't see it listed in the kits. Looks like it is QBE60G-Maz0X where there is X=1-4 and the variables are helical vs straight cut and double overdrive vs direct / overdrive. I'm assuming dog / straight cut gears for yours. What ratio set did you choose? (direct / overdrive or double overdrive) .

Thanks! Looks like QBE60G-Maz02 . I see multiple gear sets offered there and then different options on their spec sheet.
These are the gear ratio sets I saw. Is the first one the one you got? The last one I only saw in the spec sheet that didn't seem to be Miata specific.
Spur 2.400 1.840 1.482 1.260 1.104 1.000
Spur 2.240 1.694 1.333 1.150 1.000 0.889
Spur 2.240 1.840 1.482 1.260 1.104 1.000
Yes, I am serious about this gearbox after I go through my existing 6 speeds.

I assume you will do the math for your project and decide what works best for you.

Yay Brexit! These Quaifes are now more affordable than ever!
I look forward to the day you get it rolling E! Remind me again what motor this will be paired with?

Don't remind me, I bought it about 2 months too early didn't I? For now it's going into Taxi with a 180 horse 2 liter. The plan was to go into the OGK but frankly I think the ogk might not get built for a few years now. We have sort of switched gears and are focused on building our S1. That said, our S1 will be built to be somewhat competitive in ST2 and ST3 so we can drop the Quaife into it and have some fun once or twice a year with the Vettes.
