jesse gs30

I have an 06 lexus gs300 rwd and it's currently sitting on Megan ez street coilovers but they aren't stiff enough is there a way I can change the springs on them to make them stiffer? Or wat coilovers are the stiffest out in the market? Help me out please thanks

You can do custom spring rates with BC Racing coilovers.
