i installing all megan arms and coilovers, now the rear end is bouncy. i adjusted the dampening throught every setting and drove it around. still bouncy. before installed the arms i had the coilovers on for about a month and there was no bounce. will adjusting prelaod a bit stiffer help this issue. aligment is complete and on point.
anyone else has this issue?
my assumption is that the rear lower control arm ( megan ) may be causing this.
before i go about reinstalling factory rear lower control arm anyone have any suggestions?
