Tyres are good.

Brakes

Back on pads set 1 & new rears.

Front pads are done. So it seems I can manage 12 sessions on a set. Seems to be safer to swap after 10 tho. The pistons travelled far and already tore the new dust boots "-_-

Calipers discolored due to heat :3 but no fading \o/

Uneven pad wear in front. Rear left internal pad nearly gone, outer piston stuck ?
Need to rebuild all 4 calipers. Dust boots are shot.

Installed nismo fuca with -2.5deg front camber. Improved tire wear :)

17/03/24 open pitlane with speed4fun. Pads lasted 4 hours. Swapped around 3pm. Front right dead again despite extra camber. Shaved off 4 seconds off PB. Brakes (diff ?) got so hot that we lost TC/VDC, was super fun experiencing that mid corner :p At least we discovered the car is very progressive when sliding. Anyway, I’m retiring the Z from track duty. I’m building an un compromised dedicated mx5 nc trackcar that hopefully drinks less fuel and eats fewer brake pads and tires ^^"
