Update: Reached out to the company and turns out the incorrect washers were sent with the kit. They are sending the correct washers so the kit can be complete. Great customer service! The correct M6 washers will provide the needed support.

First photo shows wide washers are provided with the bolt kit. The following photos show no washers installed with the bolts. Sure enough, upon receiving the kit, M6 washers were only provided and were as narrow as the flange of the bolt. So narrow, to the point where the washers would unevenly clamp the underbody panels. This does not provide the same coverage as the OEM washers. There were also no washers provided for the M8. The M6 bolts were also unnecessarily long, and should have been closer to OEM sizing. This kit could have been worse, but it really needs to be revised to include washers with similar width as the OEM to provide the needed support when torquing the bolts. Originally bought a second set for another GTR but will be returning. Will probably buy a different brand in the future to replace the ones I currently installed.
