I'm wanting to lower my C10, but not a lot. How do I know what kit I need?
Yes, dropped spindles are the way to go, and the aftermarket sells shorter stiffer springs for more drop if you need it.Chopping coils stopped being practical 30 years ago. You can order coils cheap enough with the proper spring rate at a a shorter height for around $100(G body guys have been running shorter s10 coils for years) . But in most instances a drop spindle is enough.
A drop spindle maintains the front suspension and steering geometrty and is the easy way to drop 2". Past that you can use shorter height with the same spring rate coils to drop another inch or so. After that your changing the geometry a good amount and need to customize stuff.
