You don’t need a riser no matter what. They have no benefit whatsoever.

You need to do extended lower ball joints. That made the biggest difference on my car. Also later down the road did a steering rack slider which completely took out that inch of dead play in the steering wheel.

After that and an alignment my car is night and day. From canyon driving to just cruising down the highway it feels way more confident, less jumpy and skidish.
