Thanks for the feedback guys.
I think I'm going to go with an upgrade to the stock system for now. At first I was just looking for a simple upgrade to the stock setup, and didn't want to bugger around with getting different setups engineered.
Now that we're looking at doing more track days, hillclimbs, etc, the stock system may not be good enough, but it will be interesting viewing for people now that we're shooting it all for the web site.
I can already see you being right mystery_kid, but we'll bake the HPXs now that I've got them before switching to the A1RMs.
So the upgrade for now is a set of DBA 4000 series rotors in the new Clubspec T3 design, which we will be evaluating for DBA, the QFM HPX pads and a set of Stoptech braided lines.
Still trying to get my head around brake fluids, but I think it'll either be the Valvoline Performance DOT4 or the Motul RBF600.
Depending on how this setup goes we may move to 350Z/GTR Brembos Alex, but it'll be a worthwhile exercise either way I think, now that we're doing some evaluation work and some write ups/videos on what we learn.
