[QUOTE="Norm Peterson, post: 16490953, member: 193960"] I hadn't seen either of those references before, so I'm going to have to spend more time with them. But MM's point regarding lateral axle motion due to the PHB working in an arc being only noise compared to the lateral tire distortion that's obviously happening at the same time is well taken. I've been aware of Watts links since before getting my '08 (which I bought new). But I personally feel that a mod like that need only be done when you can recognize that something about the car is causing a limit that the proposed mod can really fix. As a (now-retired) engineer, it's going to take more than videos from companies with parts to sell and testimonials (however well-intended, I'm not flaming anybody with that). Basically I need to recognize the need myself, and work out for myself whether any particular mod is likely to help. By way of example, I didn't even swap the truly soft OE suspension springs out on my '08 until the amount of nose dive under braking started feeling like too much. Most of my track time has been on OE springs and the OE PHB (though I did do a cheapie mod to stiffen the PHB's bushings). A little more sta-bar (Strano's bars), better dampers (yellows), and out-of-Ford-spec alignment settings are basically all I've done to the suspension. Well, there's the 285/35-18 MPSS tires on 18x11 Forgestars . . . Anyway, with my car in the above condition I have Aim Solo datalogging showing peak lateral g's of 1.3 and better, and over 1.2 at nearly 100 mph. The track is fairly flat and my car only rolls about 2°/g, so I doubt there's much error involved. My whole point being that at an indicated 1.3g, it's not the PHB that's limiting you.
