i am also running to 12 infinitys but i do have a ratel on the rear door handle
other then that its perfect
The solution to fix the rattle on your rear door handle is rather simple.
All that is needed is a single FELT-FOOT... the thing that has sticky on one side and felt on the other side - they're usually stuck under items that sit on a coffee table so they wont damage the surface when the items are slid around... look under your lap-top or calculator and you'll find "rubber feet"... this is basically the same thing except its thinner and often green.
they can be purchased in a box of 24 pieces from your local store (Ralph's, Vons, Albertsons, Thrifty, Sav-on, Wallgreens, HomeDepot, OSH...etc) for about $1.99
take one of these little round "feet" and place it between your trunk and the handle (upon closer inspection, the install location will be obvious)
This solution also works great for the other door handles and to be used on your License Plate Frame
if that rattles too
these can be stacked if you need to use more than one
