For sale is a set of lightly used 3.636 R&P gears, previous owner stated he installed them but preferred an alternate setup over these, so they are still in like new shape.

These make for a nice, long gear ratio for boosted Miatas, especially those with 6-speed transmissions. Will require professional installation.

MazdaSpeed Motorsports lists them for $500 new and it seems no one else is listing them at this time, so asking price is $425/shipped in the U.S. OBO. PayPal only.

What you see is what you get:

 

Bump for price drop. Emphasis on OBO.

 

I will holler at stan, I think he wanted some.

 

So tempting...

 

Cruise in 6th at 80mph at 3400RPM FTW with this.

 

DO IT!

Yup. One of my favorite parts of having 3.6 gears on my NA was cruising on the freeway at nice and low RPMs in 6th, but not so low that I couldn't give it a little right pedal and quickly accelerate. Another was having a usable 1st gear.

 

To rest peoples worries about 3.636 and a 5 speed... i did it all of last season.

Its great and gives you nice long gears to keep you in boost vs the super sort gearing and this setup (3.6 and 5 speed) is probably better suited to larger turbo cars.

 

Sold.
