Now, class, recess is over....Professor RR in attendance, and yes, this WILL be on the Final:
The clutch case has incorporated additional rib reinforcements to reduce vibrations and noises generated by the drivetrain. The additional ribs have improved clutch case rigidity by approximately 10%. The differential has been beefed up considerably as well. By moving to an FCD material (from FC), the case rigidity was improved by 40% while the overall case strength was increased 20%. Gear fatigue resistance was also improved by 5% through a change in the shot peening method for the drive pinion gear.
I do not claim to be a Torsen expert, but some gearheads I trust have told me that the Torsen works in part by pressing against the carrier - this might explain how the few diff "failures" that have been posted with pics show a case failure. Plus, the CompTech mod reinforces the case. The ring and pinion are Miata base stock, but they have been shotpeened for added strength, including an improvement in the 2004 as noted above.
Hope this clears up the Q's. Cheers, amigos!
OT:
Tonight I am putting 6-LED lights in the 4 overhead courtesy lights in the TL. They look really cool (and very daylight-like) when the door is opened. The door accessory lights have been fitted with bright blue LED's to match the dash and center stack, and some kid at best Buy went bonkers when he saw it tonight. They look better than the bright Red incandescent ones in my bro's E55 AMG, which now has 12K miles on it with no trouble (pretty good for a Merc - that thing just has amazing straight line juice, but is it worth 2.5 what my TL is - not for day to day driving, and the S2000's handling makes my brother cry.
