Depends on the flywheel that you're using. I recommend not to use the stock dampened flywheel, and to go with a MKIV Supra NA W58 OEM flywheel which is ~18lbs for daily driving. The stock one is great for daily driving too, but you get really inconsistent clutch engagement with the dampened flywheel. If you re-use/re-surface your stock IS300 flywheel, then you need to use a IS300 clutch. If you use the MKIV W58 flywheel then you need to use the MKIV clutch.
Search for the MKIV Supra flywheel thread in this forum and you'll see the info that you need.
