OP

is the suspension bottomed out ? Can it be adjusted any more?

If it can and is dual perch adjustable- id consider to simply upgrade rear or front and rear swaybars to increase handling potential.

But if all you want is more lows and more cambers then I can't help. Check your existing setup and see if it can get you where you want. Also speak to JDMYARD In regards to an adjustable camber kit front and or rear
