As a previous simple member of the forum for a few good years before I became a trader, just to add on what others have covered already, I liked and still love the community spirit in here with members and traders offering free advice and helping fellow zedders in need, with some of the traders going above and beyond or the extra mile as they say.
One thing I never liked is the "PM me for price" reply you get from some traders, but I can see that changing into a more open market now days. The price should be the same for everyone, so can't see why you need to PM instead of just posting the price up so other interested can see it.
Now back on topic, from my experience on both 350z and 370z best combo was DBA discs and DS2500 pads. Both available from TORQEN at probably the best price in UK.
