Kit looks complete/good quality. Track width is a good question few address. Lowering these trucks is all about "profiling" and not as much thought to other appearance issues and handling. Seller should give you track width measured by wms to wms (wheel mounting surface). Stock is around 56.5". Most (but not all) mustang ll kits use the same dimension. More often than not, this will give the front tires a sucked in look - which seems to be what most people settle for. Opting out of this look is possible, but often at a higher price point (like Scott's), look at all the manufactures & compare.
