I received the 7/8” thick wheel adapters from Motorsport Technology and they looked great. They were definitely a quality product. I brought them to my Vette mechanic to swap out the C5 wheels for the C6s. I also purchased Shraeder TPS. The C6 wheels fit perfectly without using the adapters. If they were installed, the wheels would have stuck out beyond the wheel wells and as a result would spray dirt onto the rear fenders. The Schrader TPS worked as expected without any programming problems. I’m writing this as a follow up and as an FYI for members that are planning to do a C5 to C6 wheel change. The mechanic told me that perhaps the adapters would’ve been needed if I swapped out to C6 Z06 wheels. I thank the members that provided me guidance for this project and I hope this helps others that are planning a C5 to C6 conversion.
