The Best of 2021, #5: Project DBA R35 Nissan GT-R, The Ultimate R35 Brake System, Nismo/Brembo Carbon Ceramic

We have had excellent luck with Endless RF-650 brake fluid in our racing and time attack endeavors. It not only gives great boiling performance but is the least compressible fluid on the market giving a noticeably firmer pedal. RF-650 is finding its way into many high-end professional Motorsports nowadays like F-1, Indy Cars, IMSA, and NASCAR.  If it’s good enough for these, it’s good enough for our GT-R.

First, we disconnected the ABS sensors lines and brackets holding the brake lines and sensor lines and got them out of the way.

Next, we disconnected and plugged the brake lines, you do not want to risk getting air into the ABS pump, it is a bitch to get back out by bleeding!  The DBA R35 has special stiff brake lines to improve the pedal feel from the factory so we did not go with braided steel lines.

  1. As always, great content. Thanks for all the info on parts I can only dream of having. I feel I can’t even afford to read the article. (I’m one of your IG followers and long time SCC subscriber)

  2. With such a difference in rotor diameter and a greater difference front vs rear, does the brake bias change at all? 40lbs of rotating and unsprung mass saved is crazy. Makes the price seem realistic if you’re chasing the absolute best feeling possible.

  3. I had always been told that larger rotors on a street car are actually detrimental, since it takes longer for them to reach optimal temperature for good braking. Does the same apply to carbon ceramic rotors?

    1. That’s not true at all. Bigger brakes allow you to run streetable less aggressive pads on the track. Race pads will literally eat rotors on the street in a few hundred miles. Big brakes allow true dual-purpose use. More brake power is typically also easier to modulate.
