not to sh!t on your thread or anything, but arent those LS400/ UCF20 brakes? the LS430 is a UCF30. right?
from night pager:
they have a UCF30/ LS430 (third gen LS) brake kit and the caliper is smooth on the top.
I too have the LMS brakes before they put their logos on them and I was talking to Dave before he made the kit and asked him to do the LS430s because they were bigger and lighter but he couldnt get them to fit. But i guess nightpager was able to.
