The skidplate came in the mail very vell packaged (for a skidplate) and had a single small dent on the back edge of the plate, not a big deal. All required hardware was included along with a few extras, and the downloaded instruction manual is great, and there is even a video to assist with riv-nut installation. It is apparent that significant thought went into this kit. That being said, it is not the quickest install (for one person on a garage floor) and for what it is, removal will be a mild pain as well (though not as bad as the OEM NB undertray for you miata owners). It is a very solid unit, but I may go back and add a couple spacers to the rear since it is contacting the subframe (though I've heard no rattling yet). I'm very pleased with the overall result considering the design of our cars. Customer service was excellent as well, as I had to call corksport when I over-tightened a riv-nut. I'm hoping to see a mild MPG increase on the highway since this really improves airflow under the car in addition to the protection.
