I have an open 8.8 with a 28 spline mini-spool, and 4.30 gears on it all done and on my bench here, about to be installed. I've got Nitto 555R Drag Radials out back now, in 315 flavor, which hook better than my previous 335s did. I've heard about people killing their diff's at the track with the drag radials, but what parts are they killing? I'm putting the stock axles back in for now, since this is a part by part project, and am wondering how much I am pushing my luck by launching hard with my new setup. Thanks!
