The PIU rear bar is in between the ST and Steeda/AFE bars, so of course it’s an upgrade. There are a few threads with comments on the PIU parts already. The PIU rear shocks are also allegedly stiffer, which could be a great combo to cut down the understeer. I have these parts waiting to go on mine since I’ll be removing the rusted Steeda bar. All said and done, the PIU bar & shocks together all came in around $350, FYI. Not a bad deal at all.
