I'm sure you are prepared to hear people call it another Mustang 2 suspension when the only component that is M2 is the spindle. I hear the same thing with my HDK. This leads me to my next question. Did you look at using an aftermarket GM type spindle? There are tons of options out there for height and steering arm configuration options, which make them attractive to me. There are even options for spindles made to accept a corvette or late model mustang hub. I'm not familiar enough with them to know how different the SAI is compared to the M2 spindles. Speedtech makes a killer forged aluminum spindle that I'd love to try on my HDK. They are kinda cost prohibitive just to "try".
