Full Floater Rear End
 

Does anybody have a Mazda rear end with this setup? Guru Racing used to offer one of these, but no more. I know I can get this with a Ford rear end from Speedway Engineering, but I like my Mazda rearend. I've already modded it for higher oil level, inboard dams to keep the oil in the pumpkin, attachments for tri-link and panhard rod, etc. I also want to keep my original 'SE rear brakes, which I have matched my front brake bias to.

A big motivation for this is my new engine (13B-RE with 60-1 turbo), which should make at least 350HP. I imagine I might break one of my original axles.

There are lots of V8 guys running in excess of 500 hp on a stock FB rear end, don't fix it if it aint broken, if it does break look into some Mosier axles.

IMHO.

Thanks -- that's good advice. I can't afford to make the swap right now anyway, but my fear is that I'll break an axle while I'm at speed on the track. With a full floater, I'd retain the wheel -- and possibly control.

Awww.. That was a cool looking kit too. I could just never find anyone to import it.

lol......sorry Pele

Full float isnt going to be a huge advantage on such a light car.
The only real gains on a rear disc application are that the axle shaft no longer supports the weight of the car,and that a broken axle shaft is easer to extract, since its independant of the bearing/housing.

Flanged,weight supporting conventional axles will take that power with ease......its still just a 2 rotor. Not to dismiss the power youll be able to make,but typically,3-4 rotors are the ones that tend to make super-destructive amounts of lowend torque.Try Moser for some strong,stock replacement axles.
And dont forget,disc brakes out back will help retain the wheel if the axle breaks.Ive broken axles on my rockcrawler and Ive always been able to keep moving.The bearing,retainer and disc/caliper interface will keep things together,except for perhaps a little drooping.

I liked it in concept for if I trash a diff at the track, I don't need a slide hammer and shop press to replace it.
