There's a thread in here where I wrote about them. Search for my name and Dinan or PSS10s, it's in the same thread.
Basically, I wanted them because they are a no noise option, and I was OK with them only adding a bit of camber. I'm at -1.4* with the plates and lowered 1" up front. With M3 arms I would be over -2*, which is the grand plan. But I will just wait until the bushings are worn in the stock arms before putting in the M3 ones.
CSL replicas are now CSL counterfeits. Jesus saves, like Valentine1.
