Subframe options for stock sub aftermarket parts?

[DFRESH]

On the stock sub, is the reason for moving to the rack to get the outer tie rod ends away from the wheel? Wondering if you have to switch to different steering arms when you go to the rack. My outers are very close to my wheels (19 x 8's) now, no way I could go wider unless I was able to gain clearance by going up with the outer tie rod ends (shorter steering arms on the spindles) which would put them inside the wheel (from the back side of course). These are Speedtech (ATS) Spindles which have, I believe, a one inch drop or more drop. I'm planning on the Speedtech Sub myself since I have all their stuff for the front now and it works absolutely amazing. I just want to get a bigger tire under there at some point. Just wondering if I could get by for now with a rack in order to stuff a larger tire under it.
