who makes best coil over front suspension

The biggest question, FoxMopar, is what you are looking to do. Is it to be different, auto-x, cruiser, daily driver, etc. Getting into a full coil over set up can be expensive! An HemiDenny or RMS will drastically change handling dynamics. What do you plan to do with the rear suspension.? Depending on where you are headed with this build might determine how well everyone can point you in a direction!
