so i am about to build my rear end and have been thinking of getting the 03 cobra posi becuase i can get it for $175 new. I am also dropping my gear to a 3.73. But is the cobra posi going to hold up? BTW the 4.10's are for sale.

Get it, it's basically the FRPP diff with carbon fiber clutches. I run one!

i second that cobra diff. i have one, works great and its cheap. I still think you should keep the 4.10's!

I would keep them but i run out of rpm at the track so i have to run a 28'' tall tire which is fine but on the street i run out of rpm at 113 mph and 1st through 2nd spins an then 3rd whines out way to fast so i might as well go with a 3.73 it will better for the street and the track. plus i just picked up some brand new 26'' slicks for $250 =)

I've used the Detroit Tru Trac for about 4 years now after going through 3 t-loks very quickly.

You must be getting it the same place I as I did for that price lol

I've been told the posi will hold up just fine but if if I coulda afford it I woulda gotten a tru-track
