First check the bunp steer to see how bad you might be. Then you are likely going to need to lower the rack (not very easy) or raise the tie rod end. The last setup where I was able to raise the tie rod end was accomplished by drilling out the upright to accept a bolt for the tie rod connection (1/2") and using a rod end (heim joint) for the tie rod end with a threaded adapter (to attach to the rack). Then you can add shims/washers under the rod end at the upright to get the best compromise bump steer. You will likely not get "zero" for all the range and thus will have to trade off the results. I tended to set the front end closer to zero under bump and sacrifice a bit under droop. Thus the tires with more load (bump condition) will have a little less toe change. The rack needs to be a few inches longer (at the in board pivot points) to get near zero bump throughout the range. The result is the car is much more stable at high speeds and under hard high speed braking.
