Stiffer springs needed

[AlanSRT4]

Well around where I live with just 2 let alone 3 or so people in the sedan it rubs now and then and just has always felt to mushy for me like when you shift how you just feel it rock way back.

what at an inexpensive price could I get to lower the car a little and stiffen it up all at once. want to avoid the high cost of coil overs again on this car like I have on my other. thinking there has to be some combo of lower springs with a higher weight and maybe new shocks from a different toyota vehical or soemthing that might do it up
