Son just got a 05 was wondering best way to lower it just springs or or struts to seen other cars both ways don't wanna screw this one up. Just wondering what's best way to do it thx.

 

Assuming he still has the stock dampers, they are very likely shot or almost so at this point. That means shocks and springs.

If you want to do it right the first time, buy the Bilstein B14 PSS kit for $1,000 shipped. It will give you very high quality shocks that will last a very long time and ride height adjustability, which solves the hit or miss nature of using lowering springs. The ride quality will still be very good, albeit it sportier, as the springs are not too stiff like some other coilovers.
