Position Of Steering Rack

[grim32]

Just wanted to ask a quick one about the position of the steering rack and get some tips on where i should be putting it. From what ive read height wise should be in the middle of the suspension travel, people have said there is heaps more to it but cant tell me what. Reason for asking is ive got a 93 lancer which ive put the evo 3 rear diff in and converted to rwd using a sr20. Im at the point now where i need to weld up a cross member, make engine and gearbox mounts and set pinnion angle on the diff so i want to get all the info i need right before i finish any of these things.

Car will be just used as a normal street car and maybe a trip to the drags but no track racing.
