I do not race my car, I drive it far distances for my own pleasure ! The tubular upper control arms correct the fact we don't get enough camber in our cars, especially over the years as things wear and "sag" . . . why did Moog bring out "correction bushings" ??? Exactly same thing !!!

The tubular upper control arms are NOT correcting a 3/8" taller spindle . . . and if you have an "old school" experienced mechanic, they can understand the car alignment issues better than "those racing their cars" . . .

I am putting my decision on parts usage on my "real world" experience and that of those whom I trust in the hobby . . .

With your thinking, then going to a 15" wheel/tire combo which may not have been stock on a car, is a no no . . .
