a little complicated to explain. but as commented it only keeps dirt out, and I pull/check all my brakes between every DE event. got the 951 in the shop now for the full spring track prep.

good luck.
The URO scraper rings look just like the Porsche ones for the 930 calipers, the place in China probably make all of them.
