Why not just the new Magnumforce dropped spindles?
I wouldn't run them if you want to put wide 17x9 tires with 275/40/17 for a track/autocross car. With the dropped Magnumforce spindles you are limited to about 5" or so rim backspacing. And you can get 5.25 backspacing with stock spindles.
My car is about as low as I would want and still street drive it. And I don't have dropped spindles. I don't have bottoming out issues, but I had .99 Tbar and now 1.14 tbars.
