Says they exist for $599. welp. Buying this next months play paycheck. Someone try it put to make sure it is not made of hopes and dreams.
Am I missing something here? Has this always been around and I am a noob ***?

Is there an update on the 6 speed gearsets, though? I can't see how a 3.3 in a high power car, aside from giving nicer shift speeds, is going to do anything but shorten the already short life of the stock 6 speed.

for me, the thought of an extra gear on my 4.10-5speed (3.3-6 speed is roughly equivalent through 5th gear) with extra power capacity is win.
edumacation much welcome

No you've got it. Moving the fail point to a gear that previously survived illustrates my point. Which is, numerically decreasing the rear end ration increases the torque seen by the transmission gears, and for a longer time. So the transmission, unmodified, will break earlier than before.

Well hopefully MF puts together some affordable, drop in 6 speed gear set that holds a decent amount of torque to go along with the 3.3 R&P. Then they will quietly put up for sale somewhere obscure on their website and not mention it to anyone while people scramble to buy old used 3.6s. Then they take my mom out for a nice seafood dinner and never call her again.

Ordered my 3.3s last Thursday. That will be the ideal street R&P regardless of what tranny you use. It lets MF keep a nice close 6th gear in their gearset and it lets T5 guys run a .82 OD box instead of trying to bandaid it with a big deep .63 OD. Still haven't decided if I will put them into a Torsen and take my 3.63 hi-power OSG out, or swap the 3.63s in the OSG for the 3.308s. The $1800 race LSD in a daily driver is a little excessive but it hooks up so nice

The 3.3 would probably be nice for auto X with the 6 speeds. Makes 2nd about like 2nd on a 5 speed with the 3.9 which seems to be a popular setup. 7200 rpm gets you to 65.6 mph in second. No more bouncing of the revlimiter on every straight or having to shift to 3rd. Or if you have the power and feel like hurting yourself it should do 176.5mph in 6th.....yeah right..... They do have an open road race out here in western Nebraska. Not sure anyone runs Miatas but they are supposed to be the answer to all car questions right?

Been talking to Mike about the 3/4/5 gearset. I'm going to send over Miata and BRZ/86 versions of these gears so he can have a look, figure out how close they are from a manufacturing standpoint, and start getting these laid out. We have installed a Miata gearset from another manufacturer for into the BRZ/86 case with some modification, but they weren't intended to be used this way, so I am approaching the project with interchange as an intention not an afterthought.
MFactory rates their aftermarket gears at 500hp so that's the expected target. Mike says they have a stronger alloy if more capacity is required above that mark, but at a somewhat higher expense. No idea what costs will be for a set in either alloy, gotta get deeper into the planning so likely won't know for a while.
Jacks will be working in-house on development of hard anodized, billet 7075 aluminum forks for the Miata AZ6 at the request of a member here. The BRZ/86 forks are different so our existing work on that platform won't carry over (we have a 3-4 fork for that already). If I can get my engineer to focus on it I'd like to think we'll have at least a prototyped set sometime in June for test fitting.
Anyone have any ratio requests, thoughts, opinions to share? Since we are approaching this from the ground up it may be possible to tweak things a little. Keep in mind that we are only focused on 3/4/5 at this time.
If there's any wider interest in the 3.3 R&P I'll talk to Mike about pricing for a group buy.
