brake fluid recommendations

teknoprep · 09-28-2020, 06:45 AM

I only track my TT Z

Yesterday at pocono raceway I lost brakes on the infield turns and had to downshift hard and pump breaks

This was on stock fluid after 6 runs of extremely hard breaking from 145 to 60 using carbotech brake pads slotted stop tech rotors. It was obvious I boiled the fluid.

Put 4 ways on got off of race line and gave everyone point by's until pit row. At speed this is probably the scariest thing in racing to any driver other than knowing imminent death. So point to make is spend the money and get the fluid if you are ever going to track your car.

Car & Driver did the same thing back in 2008 on their first test drive and put the car into the wall

Get some proper brake fluid; even Motul 5.1 isn't really up to heavy track duty. Try Motul RBF600/660 or Castrol SRF or Torque RT700 for your needs.
