Attention all NSX owners.
The reason for this posting is to try and clarify details regarding concerns about the NSX leather interiors produced by Northwest Automotive Leather.
My name is Steven and I thought that you should know some information in addition to what Jeff Albertine has expressed. First, he is absolutely correct. We, by accident, sewed six "J" hook plastics inversely and consequently found and contacted an experienced upholsterer in Marietta, GA., so that this could be corrected. As far as the door panels are concerned, due to what looks like will be a large participation of NSX Prime members, we will for the first time offer pre-sewn, (ready-to-install) panels. (Hiya Jeff; we realize that you may feel somewhat unjustly left out because you had to pay for your panels to be sewn. Please call me personally and as President I personally will see that you are, in one way or another, taken care of)
Now, down to the business of things. For those of you who have not called me personally for answers to any concerns that you may have, I urge you to call me toll free if this posting doesn’t answer or satisfy any of your questions.
1. The first quality control system to be implemented is that a single production cell will be responsible for all aspects of quality. Usually, production cells may work on a variety of manufacturer’s models within a given day. However, to ensure that Group Buy participants receive problem-free kits, only one cell will deal with the NSX parts.
2. Fit is determined not just by product design, but most importantly by the installer. No disrespect to all do-it-yourselfers, but not everyone can be a doctor, lawyer, financial planner, dentist, electrician, etc. Therefore, please try and understand that the installation of an interior is, for the most part, an art form. Any one of you could install three individual NSX leather interiors and take a step back and examine your workmanship. What you would quickly discover is that even though the leather covers were produced within the same tolerance of quality, they somehow look slightly different from one another. This is due to the fact that the installer could not exactly reproduce the method of installation used for all of the seats. Most of you will probably get an 8.5/10 rating for the install. However, a professional installer would probably get a 9.5. This is what they do for a living. They are upholstery specialists. The average amount of time required for a DIY install =5-6+ hours. A pro install =4+ hours. The national average hourly rate is $50.
3. Leather Quality 101:
The leather used to produce the NSX Prime Interiors is Monza-H Top Grain leather. This is the same leather which is produced for Mercedes in Europe. Its sister leather is the Montana SC, which is produced for BMW in Europe. Both Items exceed British Automotive Specification Standards. Let’s be clear on one thing; Top Grain Leather is NOT the same as split leather. Top Grain is the first layer sliced of the hide. Split leather is the junk cut from underneath. Top Grain has a beautiful, suede-like underside. Split leather has a crummy, cardboard/particle board-like finish. Top Grain is used to trim the finest automobiles. Split leather, which used to be headrest/arm rest/steering wheel exclusive, is now finding it’s way onto more popular vehicle seats than would be acceptable if the public only knew.
4. Leather Quality Advanced: This leather is full penetrated and drum-dyed, unlike split leather which, (for cost purposes) is usually batch dyed in a greyish color which becomes it’s foundation. Scratch a typical split leather-colored red/yellow/green and this greyish color will surface. However, scratch the top surface of Northwest’s leather, and red/yellow/green would jump out at you from the underside. Our Leather also meets all fogging & Flammability specs.
5. Stitching Quality: All thread used for the first stage sewing process is a CBB 69, manufactured by Coats Bell, which is one of the largest suppliers of thread to the automotive industry. The thread used for the double needle top-stitching is a CBB 138. To reduce costs, the automotive industry trend is to use a CBB 69 or 92 smaller diameter for the top-stitching. We at Northwest believe in giving our customers the best product components despite the industry trend of going in the other direction.
6. Foam Quality: The foam used meets and exceeds automotive specifications. It is a medium density, open cell foam construction which fully complies with international standards. NOTE: Take a blow torch to our foam and you’d be hard-pressed to warm your hands. But, take a lighter to some of the other foams used in competing products and you might want to gather around and pull out your marshmallow sticks!
7. Machine Quality: We employ a fleet of Juki/Adler fully automated, single needle walking foot machines. The double-needle machines are $15,000. Juki postbed machines. Single needle machines are equipped with a sewing guide which increases sewing accuracy.
8. Factory Warranty is the same as special edition programs for Mazda, and Suzuki. Three years or 36,000 miles.
9. Installation Notes: The plastic plugs which everyone will be required to remove when taking off their original covers, will break. It’s inevitable due to the rigidity of the plastic used to make these plugs. If you flip your seat to expost the underside, you will notice the front corners of the seat bottom, Acura had phillips screws anchoring the interior trim. This is what we recommend using to fasten the outer frame components to the seat frame itself. We will sew a medium density polypropylene arrowhead plastic to the covers which will provide a solid anchoring strip. We will do the same for the front end seat area.
A late addition of material selection preferred synthetic suede, same-type of material that you will find in many European and North American show vehicles. NO EXTRA CHARGE. Call for available colors.
In conclusion, please call with ANY questions. We have responded to may inquiries during this past week, and have hopefully satisfied everyone’s concerns. We regret this late posting as it should have been done as soon as the first concern was expressed. We invite you to continue for as long as you have concerns to post on the forum, or
email but we can’t emphasize enough how limiting a posting is compared to a live conversation with an authority on leather interiors. Thanks very much for taking the time to read this, and have a nice weeknd.
