they are a lot better design front disc chris
should have no more cracked holes
I have found some EBC discs and cetainly cheaper makes that the vains do not both vent the same way - should draw cold air to the centre of the hub and hot air out the outside of the disc. So you get one working correctly and the other cooling the wrong way.
You may not see any effects from this but recorded the temp diff on track in the vx and is quite a bit more (I do have cooling ducts also, so that may be effecting also)
Glad to see you are still lookingafter my old silver bullet
TBH find the greenstuff pads - DANGEROUS! Yellow a bit better but since trying some proper pads I have never looked back
