Suspension help

Seeking information on how to stiffen the rear of my 2006 VW Jetta TDI.
Replaced rear shocks and still bottoms out if I’m loaded with people or equipment.

I’ve heard someone say to put Wagon springs ? Or coil overs ?
Any help is welcome thank you.

I bought some rubber coil spring inserts from autozone. The ones that you snake around the middle of the spring while jacked up. Made a big difference and raised the rear a bit too

I put these springs on both of my 2006 Jettas. It slightly raised the back end of the car and they no longer bottom out.
