When I get some time, I'll log the difference in clutch slippage in Normal and Sport mode for you guys.
Normally I'd have the data already but I rarely drive in Normal mode.

Did you read these? These aren't Wiki-anything. The Scribd paper is a peer-reviewed article written by some of the designers of the transmission in our car.

NONE of these citations state that hard driving is easier on a transmission. This bears repeating-Nowhere does it state that driving hard is easier on a transmission.
What IS said, is that slippage damages clutch packs. A firm shift, while easier on a transmission, is unpleasant to most drivers and potentially unsafe. Slippage creates a more pleasant driving experience and a more controllable vehicle. This slippage must be designed and accounted for in stress testing.
What you and I state are the same:
If you dump a clutch at 6,000rpm the clutch pack will be exposed to far many more revolutions of slippage, than dumping the clutch at 2,000rpm. Why? because it takes the clutch a longer (rev/time) to match the input rpm. This slippage eats the clutch pack.

Ugh. This post kills me. So I was right and just doubted myself. The other people posting sounded like the knew what they were taking about and had the scientific proof to back it. But now that you put it in a different perspective (dumping the clutch or slipping the clutch @ 6000rpm's) I see that clutch wear is not as bad in sport mode! TY

I've got a 2011 RA and I always drive around in Normal, but as of late i've been driving around in sport because it is cooler to listen too. I'm only leasing my RA for 4 years then i'll be free and clear of all upside down payments from my old Lancer and then plan on buying a Evo... If we still have evo's in 2015?!?

no true. Sport Auto shifts "automatically" at a much higher RPM than Normal Auto. Sport Manual doesn't shift until you tell it to, hence "manual" (to be perfectly honest I haven't tested if it will auto shift at red-line or simply bounce off the rev limit. Way more damage than I want to intentionally cause on a $10K tranny 
)
