Ok so after reading many threads on here about putting Mopar stage 1 springs on my car it seems i have the self adjust shocks in the rear. But after following instructions on how to tell if my car has the stp package on it it seems it also has that. Is this possible to have both? I thought i read on here that stp cars have bilstien shocks. My car is a 2012 r/t with a six speed...are all six speed cars stp cars? Understanding i haf to change the shocks if they are self leveling to get the lowered effect i want with the mopar springs how will the stp effect putting these springs on it if any?
