Hi Pete, they look pretty good, might try some different discs down the line, but to start with gonna use Oem items. Two reasons., firstly so l have a base feel to work from and I have had quite a bit of advice surrounding discs. Everyone can have good or bad results depending on driving style. Me personally I normally drive like victor meldrew, not cuz I am that old simply because even though she is on log, when you unlock all those horses, she is a thirsty girl, that being said when needed or wanted I can drive a car up to and over its limit, the only car I have ever owned to not get brake fade is my 79 trains am. Calibrate 4x4 turbo, Carlton 12v and 24v gsi's, Capri 2.8's, omega 2.5 and 3.0, Palermo 2.8td and my p38 so all in all I need a disc which will be driven through a very occasional flood, be durable, work from cold, and take some serious heat. You see if I put grooved-drilled-drilled and grooved discs on the front, I would want the rears to match, I have an OCD like that, everything has to be symmetrical, DVD discs all facing correct in the case, letters on my bonnet all straight ( ) etc so I have a lot of food for thought, a lot of areas to look at and things to investigate, how long have yours been fitted and have you had any noticeable issues wither Pete.
P.s. The stat mod worked out perfect, but now my timing chain guides have gone so she is laid up for a while and I have bought old 222k faithful p38 out of retirement for a while, not quite the same to drive but with the steering box believe it or not feels nicer.
