Ece 4-6 with ridler wheels?

[72tutone]

Well I bought the ece 4-6 drop kit and much like other ece guys the backspacing on my 6.5 rally wheels are too much and therefore require me to trim the lower a arm gutter back some. Well another problem has arose and I believe the answer is the same to trim. The tie rod from the spindle is also hitting the rim, so I've come to a dillema. I have since sold my rally wheels and I'm interested in the ridler 20x8.5with 4.5 bs and 20x10 5.5 bs. So what I'm trying to find out is if backspacing is the issue how is everyone running drop spindles on the bigger size rims? Is it the sheer size of the rim where everything is nicely tucked inside the rim? Or will problems still persist regardless?
