Lowering springs

[Bob24]

I am thinking about getting some lowering springs for my M45. I have seen the ones from Eibach and saw them on a forum member's car and it seems like a nice upgrade.

The springs themselves are reasonable at about $200-250 but does anyone know what kind of labor it entails putting new springs on? I also wonder what, if any, effect it might have on my factory warranty.

Anyone have any idea?

I bought a pair of Tein S Tech springs and I buddy and I started putting them on and then kind of stumped on it, but we have figured it out now and are going to give it another shot when the weather warms up. I do know the rears are a lot easier to do then the fronts
