Coils Springs... Any Brand Better Than Others?

[C10_ustacould]

Looking to swap springs in the "Ole Girl". It has cut coils only in the front (3") and 5" drop springs in the rear, we'd like a go to 4.5/6 drop. We'll be adding drop spindles with a drop spring up front versus the very short cut spring only. My first build used ECE springs, and the trucks I've had since have used CPP springs. Seems to me the ECE springs were a little tighter, less spongy than the CPPs if that makes sense. The black KYB shocks that came with my ECE kit lacked control in my opinion but I think the grey KYB Gas-A-Just units would calm that down.

With all that said, what are your thoughts on the differences between ECE and CPP springs?

Pic...just because.
