Thanks guys - really appreciate the feedback...wish there was a way to easily multi-quote on here, but oh well...
So couple things
adding the spacer to one side will effectively make the rack wider, my biggest obstacle that I still think will be ensuring the tie rods are the same length, have to address how to get this correct, but it will keep pivot points in the same plane horizontally
the rack is already "slightly down" from the factory, BUT, with the subframe location, it should keep the tie rods parallel with the control arms, so i think i will be pretty good in that regard. the issue with going down too much more and keeping the L/R from the factory is then the rack very much becomes the lowest point of the car....again, not the end of the world, but something i would like to avoid b/c it will be use a lot on the street
front to back location is pretty close to where it was from the factory, so i dont think i should have too much impact to ackerman
The other option I have been thinking about is cutting up the oil pan, it is a very strange 2part design where some of it is aluminum with a steel bottom part, so I am going to see if i can modify the steel part enough to get the clearance that i need.
again, really appreciate the feedback, anyone else that has suggestions i am happy to hear....at this point i am thinking that it might be in my best interest to get my engine mounts made and start addressing the rack location after that is finalized
