Jason,
Yes I have. A number of years ago, I installed a MM Road and Track Grip Package on my wife's '06 GT vert (Tokico D-Spec, H&R Sport Springs, MM CC plates, MM Panhard Bar, Eibach f/r sway bars). It had the same affect...much crisper ride. I recently installed Ford Racing RLCA relocation brackets and Eibach RLCAs....this took care of the axle hop under acceleration.
Recently, I installed what is essentially a MM Road and Track Grip package on a fellow BMO member's 2012 Boss 302. MM CC plates, Koni Sports, Ford Racing P Springs, Ford Racing RLCA relocation brackets, Ford Racing Panhard Bar, and Eibach RLCAs. OEM Boss 302 sway bars remained on the car. All of these components have been used together as well by a number of BMO members with similar results. Vast improvements in ride, performance, handling, turn in, reduced nose dive...far better than stock. With this set up, there wasn't any increase in NVH....no rod ends.
When I spoke with Kenny Brown prior to buying the AGS-4, his goal was to reduce the number of adjustments and fiddling with suspension set ups as the vast majority of folks with adjustable set ups don't use the adjustments. So, the AGS-4 I have on my LS is essentially non-adjustable (with the exception of the front sway bar)....KB did all of the engineering and testing, which works for me. Even after experiencing the dreaded steering shudder (likely induced by changes to the suspension geometry and steering feedback) which the EPAS rack solved, I'm still a satisfied customer.
