i agree. lsd made a huge diff. my car felt unsettled in the rear under hard braking. adding an lsd eliminated that. i dont get nervous when jamming on the brakes from high speeds.

btw, 7mm shims ?
i thought it was 10mm each side??

I have all the solid arms in the rear but was still getting the back end moving around under braking, kind of a scary feeling actually. Once I installed a Guard Club LSD, voila, car tracked solid as an arrow under braking. Matt set mine up with a 60 lb preload IIRC. With a moderate preload in the LSD, the rear wheels are effectively "tied" together and really stabilize the car as the back end unloads during hard braking. If you have an open diff, there is nothing to tie the back wheel together as they are basically freewheeling. The "wiggle" is generally also a way to tell if your LSD is getting worn out, your car becomes unstable under braking. Most GT3 guys run into this problem after only a few track days with the stock Porsche LSD as it is set up with a preload of only about 7 lbs and quickly wears out. It still locks under acceleration but is useless under braking. What type of diff are you running on your car btw?
