No posi? WTF
 

Alright well I was messing around on my friends street and he told me to do a burnout, so I left a pretty long burnout down his street. Anways he sends me a picture and its a one tire fire!

So on top of what I already have planned for the car, would a used 4th gen rear end be a decent idea? Should a rebuild be in order if I decide to go through with it? How hard is it to do?

Input needed!

Not sure what your best route would be, but my car did this the other day, it ALWAYS grabs posi, I linelocked second, and then walked it out, and the next day.....one leggah haha

If you are a 6 speed get a built rear like a 9" if your auto a stock rear is fine

^^I second that, blew my rear end on bald tires with half throttle

Automatic. Would I be better off with an ls1 rear end?

ls1 rear end is the same except the brakes and rear diff wich hasnt proven to me its stronger. Plus you would have to swap the brakes over anyway. so LT1 rear with a higher(numerically) gear would be best. the highest gears GM used in the A4's was 3.23 im guessing you dont have them as they came in special packages in the LT1. SS/WS6 Mostly. So get a 3.23 or 3.42 rear end. BUT with getting a used rear end you run the same risk of That posi being on the way out too. just some food for thought.

Get whatever you can find with the least miles there are small differences tothe posi's but i don't feel any are stronger then the other.

I Mine has 3.23 gear option. Only reason I asked was because of the brakes because I want to upgrade them at some point.

But when I go through with this, strength really is the same for all 4th gens (minus the sixers)

mine has 3.23 too :crazyhi:

Ive got a Moser 9" for sale, wont break that one :)
