I'm finally ready to order a set of springs for my m45. Now I'm stuck to which one to buy. I want to go as low as possible without needing to buy anything extra to fix the alignment and I don't want to worry to much on dips or bumps on the road but I do want a nice luxury look and feel along with the comfort level being the same but with more responsive and safe feel. I also don't want any issues when putting on my new set of wheels that will be 20inches instead of my stocks which were 18s. So out of the two Tein springs I'm looking at, which one would you guys go for? Also another thing to keep in mind is when I do drive the car I usually well not usually but Always have my wife and my two boys in the car, I just thought I'd put that out there for those concern about weight

. Anyway I look forward to making my decision soon and I hope you guys can help me out. I'm aware that the two springs are only made for the M35 but I was also told that they will fit with no problem on M45s
Good Night,
Jeff
