+1. Get it. Don't be a *****.

 

1.5 way or 2 way?

u should just get new axles from rx7store.net

 

a buddy of mine with a 2 rotor shattered his diff, so he got in on the cobra rear end group buy. I saw the parts, they are all top notch. Looks VERY strong.

also, a 1.5 is probably what you want unless you're making a drift specific car or very high speed track car.

 

Ok guy's thanx for the info but how much power can this kazz diff handle???that is what i would like to know..

 

I am wondering more so what the stock casing can handle?

The kazz diff i am sure will take 600+ ft lbs but will the case explode before that much like crisspeeds?

 

KAAZ !!

 

****.... in less than a year i will be running a 20B FD puttin around 500-600rwhp....

my plan is to go for rx7store aluminum driveshaft... kaaz 1.5 way... and rx7store 300m axles


what do u guys think... will it be ok?

 

Don't forget some sturdier diff bushings.
