[Can't kech me]

daydreaming here, i'm set in stone that i want either american eagle 225's or boss 338's in chrome. when i lower it ( hopefully soon ) i'm gonna go with sport truck direct's 4/6 economy lowering kit. to add a little rake i may replace the 1.5 inch drop coils that come with that kit with 2.5 inch coils. i know that their deluxe drop "b" come with a towing bag kit for the rear and new leaf spring for a smoother ride. but is it worth it? because it's nearly $300 more expensive...
