Currently everything is stock as a rock - OE 296mm rotors and the standard Nissan/Sumitomo caliper with an unknown pad. At the cars first track day at Wakefield on 28/5/2011, I had a lot of vibration and not a lot of stopping power by the end of the day. Stopped well enough at first though, but I wasn't pushing it too much.
I am definitely up for rotors now and have been quoted for a pair of DBA4000 XS which with decent pads I understand will do the job for a while. It's relatively cheap (under $800) which is a factor.
And here's the but: I'd like to be doing more track days ideally once per month or every two months at least. If I spend more on a brake upgrade now, will it save me more later and most importantly will I be doing better lap times sooner? If the answer to this is yes, then I need new, bigger wheels and tyres as well so the costs are escalating exponentially!
Who thought motorsport would be expensive?! haha
