The bolts at 20, (21mm) on Dellmasives print are torqued to 180Nm and a quarter turn so Dells breaker bar is a must to shift the sods. I would also recommend a 6 point socket rather than a12 and this attachment for the breaker bar.
I also had to use foot power on them with a breaker bar. I put Brembo on the rear and up to now are very good. I also changed my brake fluid while I was at it.
