aftermarket 2way LSD setup(locking % strength)

[NickBW]

Hi, I'm currently in the market for an LSD for my ae86.. I'm leaning towards a Tomei 2way LSD which I have heard good things about. My dilemma is I'm not sure how I wish to have it setup, locking strength wise. Since I will probably to do more typical autocross and track days then drifting events as it being my primary street car I'm a little nervous about just going with the out of the box setup which I would assume is more geared to drifting since that is what the vast majority of the people who purchase them will use them for. IIRC kaaz's are set at 100% out of the box.. and for reference my understanding is that bmw m3's are around 25%. So any recommendations for good compromised setup to do it all? Also, assuming you guys recommend with a much lower then out of the box setup.. since I'm not focused on just drifting would the aftermarket LSD still be that much more beneficial to an OEM ae86 1.5way LSD?

Thanks.
