To tighten up the steering on an AE86 we would replace the power steering knuckles with non power steering knuckles. The steereing is quicker. Lock to lock is reduced. Make the car more like a go cart. Power steering....... The MR2 is pretty light in the front end, and steering is pretty easy as it is. But in the interest of reducing driver fatigue I have a thought of installing power steering. I can take the rack out of my black AE82, along with the pump and brackets. The lines would have to be fabbed, but that won't be too difficult. Just a thought.
