Do you already have the Monroes?
If you don't, SAVE YOUR MONEY and spend it on something worthy. BAT, Koni, etc..
Monroes are adequate OEM replacements for old folk with leaky struts on their beige cars. If you're considering lowering springs, you want to team them with performance struts. Make sense?
If you alreayd own the Monroes, it's not gonna be the end of the world, but definitely don't spend money on them if you haven't bought yet.
