what would be the reason to run these over coilovers???

Lower the car, but not lower the roll center more than the CG, which is what will happen when you lower it with springs or coilovers. It'll also keep the factory geometry, which on almost any car, is less than optimal when lowered. I don't know the details of an FD suspension, but I'd immagine it works best at stock ride heights.

So at the same lowered ride height with these + coilovers vs. just coilovers, the geometry will be improved, as will the roll couple. They're probably lighter too.

wow sounds like a worth while mod for a track guy

In other words, drop the car by using this, keeping factory suspension settings and ride "confort".

i wonder how those would work for those running 20Bs since they have to get theirs moded for torque steer?

You've missed the point. The point is to regain some of the lost geometry on an already lowered car in order to get better performance, but you could just lower it with these and maintain comfort.

20B's have problems with bump steer, torque steer is a phenomenon that affects front drivers.

as i understand it the bumpsteer problem with the 20b is do to some coversion kits relocating the the rack screwing the geometry to the spindle, these will not affect that. they will however allow you to maintain a much closer to stock roll center and camber gain geometry on a lowered car....I haven't run any of the numbers but i would be curious how much of an effect the change in king pin angle would have (how much castor will this add?).
