Don't want to go against the grain here. In general stock clutch for stock trans is a good rule of thumb. However a stronger clutch is not in and of itself going to stress your trans. It's only going to stress it if you take advantage of what the stronger clutch is capable of. Drive it in a reasonable fashion and it will not hurt the trans.
I replaced my stocker with a ClutchMasters 300 kevlar clutch. The engine was detuned to about 300whp/270wtrq. The clutch turned out to have a bad pressure plate. A LOT of shudder in it. Clutch was replaced under warranty: no vibration, very smooth. I drove it this way for five months, with a stock trans.
Pulled the trans to replace the stock gears with heavier gears. The OEM gears are in perfect shape. Moral of the story is . . .
(All you have to do is turn the flywheel. No need to replace it unless it has been overheated.)
Very true TwoCobras, but we have to ask ourselves who will actually do this and pay attention to it. Im probably wouldnt even count myself to do it. Thats the only problem there. But if new gears are in mind down the road, and a person can drive sensibly, then an upgraded clutch isnt a bad thing either.
