its all relative..it depends on how you drive ( ie are you an ex honda owner who likes to "chirp" gears) .. how much power are you making ?.. what will you be doing ?.. all that adds up.. for a daily driven (responsibly) car with less than about 350 ft/lbs .. some mild launches .. but no side stepping .. i'd say the RA stuff will hold up fine..

its all in how you drive it.. how harsh you are with launching.. i know plenty of guys in ausralia who break dog boxes with 8000 RPM side stepping .. and quie a few on stock trannies with 400 ft/lb ..its all in your driving.
