i want a set, so long as its drivable for street
Its suitable for street driving as the ackermann angle is pretty much near stock. It is a copy of the c-one steering knuckles so you should get about 2.5 turns lock to lock. It will make the steering a bit more responsive (read - twitchy, as little inputs to the steering will equate to more than stock, due to reduced pivot distance) but you just learn to drive with it, and you get used to it pretty quickly. It will also make your parallel parking just a bit easier
These are also useful if your car is dropped a fair bit and your suspension arms are pointing upwards. These knuckles could eliminate bump steer and make the car handle a little bit nicer due to the extra thickness.
