So avoid Tein, as their base setups don't allow for independent adjustment of damper stroke range & ride height. For reference, most companies refer to this as "adjustable preload". But its a totally inaccurate term for the application. you'll want one that does adjust these settings independently.
If you were to do a more modest 1 to 1.5" drop then a good spring + damper setup would probably be preferable if just for the improved ride quality that progressive springs offer.
