Half shafts did not break in any of these instances. Yes it's tough to lay down these times and it's harder on an IRS than it would be a straight axle. Then again, I think most people prefer the IRS on a daily driver.

"official stance militant and aggressive with product support" Really? Heard few complaints from owners on product support.

On product defense in this forum, aggressive yes, militant seems quite an exaggerated characterization. I think any aggressiveness is in direct response to mischaracterizations of the product. We keep getting a bad rap for running a BMW diff whose LSD tends to be more safe than locking. But if you ever see a BDR take off in a straight line, we definitely spin both tires. LSD option there, and pretty cheap.

FACT: Nittos get us better times, but it's obvious we can stick to the 315 17" goodyears, standard diff with a decent gear like 346, play it safe on the half shafts (with the goodyear) and still pull some killer 0-60 (sec) times.
