I know that the older throwout bearings had issues and that there is a new part that fixes it. I am not sure if the exedy oem kit I bought contains the new or old bearing.
Assuming I got another old bearing, what can I do to prolong the life of it? I always hear that the throwout bearing should outlast the clutch, but it certainly was not the case for me. Does shifting at higher rpms cause quicker bearing deterioration? I am assuming the bearings have a set life expectancy of rotations it can go through. If shifting at 2-3k can help the bearing last longer I may consider to do that.
Anything else other than getting off the cluth faster affect the throwout bearing life? My old throwout bearing crapped out at 80k. No serious power mods besides e85 for the last 50k miles.
Wanted to get some handy tips on how this all works. Thanks for your thoughts!

I'll ring up our resident TOB expert @
Tcoat for his thoughts.
My understanding is that the TOB on these cars is going around any time the engine is running. It's just called upon to "work" when you push the clutch pedal down.
Therefore, the less you drive your car - the longer the TOB will last - daaaa
The fewer times you push in on the clutch, the longer the TOB will last - another daaa
It's also my understanding is that the old TOBs went bad because they ran out of lubricant. Heat is their enemy, therefore the less the clutch is used when the drivetrain is extremely hot - the longer a TOB will last.
If your replacement kit included the "new" TOB, I wouldn't worry about it - it will probably last longer than you keep your car.
If the kit contained the old type TOB, you might budget for a replacement in another 80,000 miles. But, I still wouldn't worry about it.
