Dropped Spindal Question

[carkrazy1987]

I reviewed all the previous post of dropped spindals vs drop springs, but i did not happen to see what i was looking for. my question is at what size tire do u start to run into the tire to tie rod contact problem. i plan on running either a 17x7 or 17x8 up front, and drop springs are my first choice. i was just curious to find out what size tires could be put on my nova with dropped spindals. i wana lower my car 2 inches, but i may want to lower it 4 in, thats why im askin. r should i not bother trying to go that low cause of ground clearance issues. Thanks
