Okay I've started to look at getting a suspension for my 2002 9-5 sedan and am looking at the Bilstein B12 kit but the way its listed is really confusing there are 2 options
1.Is to chassis # YS3ES55CD1
2.Is from chassis # YS3ES55CD2

So if my vin is YS3EH45G923047954 I'm guessing I'd go with option 1. Correct?
Also does anyone have any experience using the B12 suspension? Ive also heard good things about maptun coilovers and konis,I want something very stiff and sporty for better handling and cornering are there better options? I haven't been able to find a clear answer anywhere.
Thanks for the help
