I have the weir 12 plate rear diff mod. And I had tons of noise and chatter and popping. I contacted weir and he sent me out two thinner spring plates and now it works like its supposed to. No inner tire chirp on tight turns, no loud popping and great lock up and power oversteer
Not trying to thread jack but as I just upgraded a bunch of my drivetrain stuff with Jacks Goodies(TC/Tranny/Clutch) what made you choose quaife vs. wavetrack? I am assuming this is what you did or you wouldn't have made that reccomendation yea.
I chose the quaife over the wavetrac just because of quaifes long and great reputation. Wavetrac wasn't as known when I did the upgrade and I chose to go with something that had a stronger background. Both are great diffs and act exactly the same. I'm sure if you had both and did a back to back testing, no one would be able to tell a big difference if any at all
maybe its the grass is greener on the other side but I have an 03 and i would like to have acd. you can actaully tune the acd ecu and make it naturally oversteer, understeer however you like. if you search it on here youll find it.
