Well I can tell you the difference between going with a NSX trained Tech at an Acura Dealership is hands over better quality and care than going elsewhere. The Dealerships take the NSX work seriously and will not take shortcuts as the liability is too great in their minds. My Santa Barbara Acura Dealership had the one NSX trained Tech retire. They will not do an oil change for me as they will not accept the liability for allowing a non certified NSX Tech do the car. It is not that they cannot do an oil change, they will not risk something happening as a result of not following the specific guidelines. Eibach is a good company but you can bet they do not do too many NSXs. They will take what shortcuts they can figure out. For instance using a impact wrench when the Factory calls out to do things by hand.
When I had the OEM springs put back on, I was told that there was concern that some of the treads had been damaged. They showed me the aluminum fillings. I was not sure what could be done if the threads were damaged, so I was getting prepared for having to have inserts installed if necessary. I am not sure that Acura would approve inserts, but from my Aerospace days I knew they work. But Tustin Acura contacted the Factory and they decided that replacing the bolts would be the way to go. At Tustin they torqued everything per the factory. They would not do the car unless they were confident. After all this is Honda/Acura's Pride.
I have uploaded pictures of one of the bolts as well as shots of the fillings on the threads. These pics were taken by one of the NSX Techs (Norm who has been there for 35 years) at Gold Coast Acura in Ventura. He removed the struts but was unable to remove the springs. Acura does not make a tool to allow repair of the struts. You are supposed to replace at $500 each. They put my car back together and did not charge me for all the work. At the time I did not know that SOS sold a tool for this specific strut. I contacted Sarah and she thought they had all the tools. Turns out she did not have the specific tool. By then I was able to inform her about the tool from SOS. They tried to see if someone local had one but ended up overnighting the tool from SOS to insure they could work on my car and do it right. I had informed her about the threads so she did her best to work with the Factory to insure the car was done correctly. The pic of my car on the lift is from Tustin Acura and it shows how my car is protected with the appropriate NSX covers. They are worth it.
Again, I have no skin in the game and could care less where you take your car, after all its your money. I am just telling you what I believe.
