Which diff for a 4th gen? Auburn vs Detroit vs Yukon vs ??

I'm pretty sure my T2R finally bit the dust today. It was locked up after the last race and hopped and clunked its way into the trailer. I knew this day would come and I'm pretty happy with its mode of failure as it allowed me to finish the race. I can't believe I didn't feel it on track though, I imagine turn in should have suffered if the thing was locked up out there. I'm seeing Auburn makes a cone diff, Detroit makes a torque sensing diff, and Yukon makes a clutch diff. What are you guys' experience with these diffs? I'm wondering how they compare on corner entry as I figure all of them will leave 2 trenches on corner exit.

I've only had the Auburn... supposedly you need to send them in when they stop working. I think it still works, but i never follow me.

I tried!! Lol

I fried my t2r last year, I went with a true track.

I ran the Auburn Racer's diff for a couple seasons and it was good at first but the clutches wore quickly and needed a rebuild after 4-5 weekends. Got tired of that so I switched to the Detroit Tru-Trac the last couple years and am pretty happy with it. Same behavior with the way the car turns in and puts power down but without the wear issues.

I'd go Eaton Posi if I had a 10 bolt. My T2R has been reliable in the 8.8, I also have the boss 302r version which I heard is more durable to meet ford's requirements.

Is there a trend that Torsen T2R diffs are blowing up in the Camaros or have there been failures in the Mustangs as well? I hope it is a Camaro/torque arm/axle hop issue as I just installed a T2R in my Mustang with a poor man's 3 link.

I scoured the interwebs about T2R failures before buying my lightly used unit in 2012.

T2Rs originally were fine, *something* changed in the mid 2000s which is when the failures started, then they fixed something by the late 2000s, and no more failures. No one knows what changed (and changed again) and Torsen never publicly acknowledged what happened.

I haven't broken mine yet; had a close call with the ring gear bolts issue at Hallett but that wasn't the T2R's fault.

Mine was built in the early 2000s so no durability complaints here. Just wanna see what's what today.

Eaton in Misty's 10-bolt lasted for YEARS even behind 400rwhp. Only car I know of that never lost a 10 bolt. Currently running an Eaton Wavetrac (think Torsen but still works with a wheel off the ground). LOVE IT!

Matt,
Are you running C-Clips with the Wavetrac?

9" ford doesn't use C-clips so no.

My mustang which is running the 8.8" is still running the Eaton HD that I installed in 2002.
