I'd suggest calling them or sending them an e-mail. I don't believe what you have noticed would make any difference but contacting them will help you feel comfortable.

I have one of the plates and I really like it. I also have their maincase and a few other parts. All excellent.

With my plate, I don't use studs, lockwashers and nuts. I use cap head screws and flat washers. I believe this is what WEVO use when they build racing transmissions. The high quality cap head screws are drilled for safety wire and I use a little blue loctite as well. The safety wire is a little bit of a pain-- but I I have gotten rather good at it. I am sure for 99% of applications, the studs and nuts are fine. My application is a pretty stressed one.

Since you had the original plate come loose, I would do a really thorough inspection of everything-- either yourself if you have the experience or have a really good shop do it. I know from experience that there are some subtle types of damage that can be existent but difficult to detect. These can lead to future mysterious and expensive failures.

Anyway, I doubt the characteristics you have noticed make a difference, but when in doubt, just send WEVO an e-mail. They are absolute experts, and really stand behind the design and manufactured quality of their parts. We are lucky to have companies like them making key parts for the cars.
