ok my rear end is clunking like a **** and its time to replace and just do it right the first time.....so the two routes i was thinking of going with was A: kaaz 1.5 way and B: i called pettet racing and they said for 1000 bucks ill get a rear end with a rx7 lsd in it which is similar to a turbo 2 rear end and they are supposed to be like bulliet proof....anyways they both cost about the same.....this car is NOT a daily driver and i mostly drive it on the weekends...i just want something that is gonna handle good and be able to handle a track day here and there with 500hp to the wheels ....any help would be great thanks

 

If I was going to spend that much, I'd go all in for the 8.8 and be done.

 

Not interested in a Ford rear end

 

is the clunking produce by the diferrential or is it the bushings and pillow ***** on the rear suspensions?

is it clunking all the time while driving or only on stop and go?

 

if in fact the lsd is making noise you could get a S4 T2 lsd for less than 300 and install it your self if your good in DIY.

 

so i would just get the lsd for a t2 and put that in my fd diff case and be good?

 

it clunks when i shift to fast or i take off to hard

 

86-88 T2 is the best one

 

that maybe something else, did you replace the stock diff mounts?

 

doubt thats your diff. do you feel it in the transmission when you shift? or in the body of the car more? How many miles on the car? do you have aftermarket bushings or Pillow *****? 99%of the time the clunking from the rear is either pillow ***** or your PPF (power Plant Frame) is cracked.

 

well i went with the Kaaz 1.5 super Q which is their new line its supposed to be very quiet...just gonna rebuild everything with that

 

Let us know if the diff solves your problem and how like it. I assume you're installing new bushings with the new diff? We might not know if it was actually the diff or the bushings if that's the case.

What ratio did you decide to go with?

 

got the car back a couple of weeks ago and its driving great!!!! no more clunking and the lsd is not loud at all......i had them set the discs to 66% locking insted of the 100% because its a street car....no lsd engaging sounds nothing....i love it
