Megan Racing Coilovers Install Question

[Zreberlcoe]

When installing the Megan Coils, you know how much to cut just by measuring the inside of the tube they give you up to where the machined inside changes diameter? Not to where the threads start right?

incase you're still wondering when i installed my megans i cut about as high as the shiny part on the coilover it worked great
