Lowering superstrut options.

[TRD_ZERO]

My rear coilover shocks are poked. So i got some adjustable shocks to replace the coilovers. Now i need to lower the car a fair bit. The coilovers didnt lower the car enough anyway when fully wound down. So my question is what route do i take to lower it. Do i compress the factory springs and shorten the shocks. Or get a lowering spring, if so what brand and where to get them for superstrut. I want the option that wil help the shocks last longer.
