Alright you suspension Gods out there i come humbly before ye, hear my plea. ok on a more serious note, i bought some used coilovers that came with "swift" springs, i'm having my doubts if they are actual swift springs or rather some other type of aftermarket spring. From what i see from the boxes the front springs are rated at 12kg and the rear are 10kg. however on the springs themselves they are marked with completely different markings, 21kg in the front and 17kg in the back. i'm completely lost, i'm new to the suspension world. are these swift springs? if not can anyone help me ID them? please help me you guys, thank you.

I'm not an expert but i highly doubt those are Swift because 1. Swift put their name on the springs and I don't see it there. 2. Swift springs have more stroke, less coils. You can try to email them and ask?

Also according to the part number on the box those are 20kg and 16kg
