1. I run 34F and 35R for both road and track. I was tempted to drop the rears a smidge on the day when they started to slip through heat, but looking at the sidewall wear I left them alone.
2. Endless RF-650. Not cheap given they used to use it in the Honda F1 cars, but it's proved to be worth every penny and the fluid is still looking & feeling good.
3. Front compound is the PF 01 on matching PF discs, and I'm using PF Z pads on the rear with OEM discs.
4. Loads and loads, I absolutely love these pads! Minimal dust, tons of stopping power & fade resistance, and they've now seen two UK trackdays + the Ring and I've barely touched them.
5. Given a healthy budget, I'd change the suspension for something a bit harder but without going much lower to save the front bumper, and I'd love to go for six-pot front and 4-pot rear brakes. Oh, and a supercharger to be able to keep up with the quicker metal!
Realistically though that would almost be a bit pointless as a Roadster (and a 350Z in general really) isn't the best place to start for making a Ring weapon, so I'll probably just fit a set of harnesses to give me more feel from the car and enjoy it as a fast road rather than a track. If I'd have had a few more weekends available before I'd gone the harnesses would most likely have been in, just a shame time didn't allow.
