If you off road do not get cross drilled discs, dimpled and/or slotted are fine though. I purchased MTEC awhile back, so decided to check the 'service record' on my long running thread on 'MUD', it turns out I fitted them in December 2015, I cannot believe it is over three and a half years, anyway no issues, so I am a thumbs up for MTEC kit.
