I know this thread is a little old, but I figured I'd throw in my .02 as I had the same question as I put things together on my car.
Thanks to strong recommendations from @
CSG Mike and my local shop, I ended up going with the Racesengs and have been very happy. While I can't comment on durability as I have only had the car on the track for three days since install, there is no noise from the plates, no movement in the adjustment once set and no other issues I or my shop have identified. They sure do look pretty as well!
I'll add a big thanks to CounterSpace Garage again as they have given me excellent advice every step of the way.
