*** Edit: Final rotor selection/install and track day performance on Page 3. ***
Looking forward to another track in March and I’d like to push the brakes more than during my last outing. My last outing was a refresher day after several years off and I was fairly conservative with the brakes, knowing I was only using street/track Porterfield R4S pads. They held up fine for the most part with me but after four laps with a pro driver at the wheel, they were at their limit.
I’m planning on swapping in Porterfield R4 pads up front while keeping the R4S in back for my next outing. Although I can probably use the same rotors due to compound compatibility, I may go ahead and spend a little on some 2 piece rotors for weight savings, better cooling and to protect the wheel bearings from the higher temperature range of the R4.
Anyone here using a 340mm 2 piece rotor on their track setup that they would recommend? I see there’s a handful of options out there, with the semi-floating Clubsport rotors at the lower end of the spectrum in the $500 range, with Neuspeed, etc in the $800 range.
I know I can spend a bit more and get TTS or Macan calipers, but I’m just interested in rotors at this point. Wondering if the 2 piece rotors are worth the expense.
