I wouldn't ask for your money and sell you junk.

These will be "race" caliber parts, made by a reputable manufacturer.

(That means better than stock gears.)

 

Who's the reputable manufacture?

 

No, Erat, that's the actual Name of the company "A+ Reputable Manufacturing"

 

This would be preferable to the 3.63 for me. I'm in when you start looking for $. I'll probably see it here before fb.

 

The manufacturer will be named when I post the details about the GB.

Thanks for your patience!

 

If there's one thing I know about Bill, its that when you buy one of the MR products, you're not just going to get that product, you're also going to get every part to install it, and then some other parts that go along with what you bought that you have to look up what they do because you had no idea that you actually wanted them, and you'll end up with a small tube of more loctite than you'd ever need to do the install. So knowing bill, the R&P kit will come with new diff bearings, a tube of grey RTV, some loctite, all the seals for the diff, and a crush sleeve eliminator kit, along with a few parts I didn't even know were in the rear end even though I've had a bunch of them apart and swapped ring gears before.

 

I'm guessing that Leafy is referring to the shifter kits. Thanks for the kind words, but the differential is, well, different.

I can't offer "crush sleeve elimination" as part of a kit because that's a specialized machining process where the machine shop has to have the actual pumpkin and gears in their possession to create a solid spacer tube. I can refer people to a respected colleague of mine who offers that service, plus others including reinforced saddle caps.

The following will be explained in more detail when I formally announce the GB, but my plan is to offer people two kit options: "Basic" and "The Whole Enchilada."

"Basic" kit would include the 3.3:1 ring and pinion, a crush sleeve, and a pinion nose nut. This would be for people low-mileage differentials where they are confident that their bearings and seals are reusable.

"The Whole Enchilada" kit would include all of the above plus (4) bearings and (3) seals. All of these would be genuine Mazda parts.

I can also arrange WPC Treatment as an upgrade for either option: WPC - Metal Surface Treatment / Micro Shot Peening

FYI, cryogenic treatment is not recommended by the manufacturer because the gears will be heat treated.

Thanks for your interest and patience!

 

Weir performance already makes the crush sleeve eliminator for our rear ends. So no need to have them custom made. They get around the custom part by having a basic solid tube made and having shims.

 

Thanks for the tip! I'm going to set up as a dealer for those and I'll make them part of "The Whole Enchilada" kit.

 

Just found out that I can adjust my speedo calibration with my Hydra.

 

A simple GPS device should take care of the need for a speedo. Or just tape numbers like O5pearl suggested, haha.

 

Was looking into doing this myself...easier to give Bill $.

Yeah I'm probably going to end up getting a set of these since they make the 6 speed gearing make sense. As much as I didnt want to spend this kind of money this year.

 

Get Adam (revlimiter) to make a customer set of gauge faces for 3.3 gears. Done.

 

Odometer will never be right.

 

What Savington said. Even if it was possible it would be difficult to make to scale and it would look really weird because it is a percentage scale not a fixed amount that it would be off.

 

Excuse my ignorance but why would someone want these gears? I know with 4.10's I use 3, 4, 5 & 6 on the track. Would I then use 1, 2 , 3 & 4?

 

Are you trolling?

 

If you're cruising at 80 on the highway would you rather be at 3850rpms with 3.90s or at 3250rpms with 3.30s?

I have to think above 300whp you're going to pick up some significant overall acceleration compared to stock gearing with a 6 speed. 3.90s are great with 100hp, but as power increases you're really rowing though the gears. Maybe it's different for all out track cars, but these seem like a great idea for those of us who spend most of our time on the street.

 

Of course not it was a serious question.
