Project Infiniti G35 Part 2: Improving Stopping Power with Brembo, Project Mu and DBA

By Mike Kojima

In our last edition of Project G35 we set out to improve our handling with some suspension by KW.  To keep things in line with having a balanced performance daily driver we next turned our attention to the brakes.

Our stock front brakes are your typical pedestrian single piston floating caliper with a rotor of moderate size.  They are OK for street use but not any sort of track or hard use.

Our G35 is a street machine for the most part so we felt that having the latest in extreme floating rotor gigantic brakes would be overkill.  We didn’t want the NVH of floating rotors or the potential noise of hardcore performance calipers and pads on our daily driver.  However we did need better brakes.  Although Project G35's brakes were adequate for pure street use, on the track, they quickly faded away after about 2 laps even at very moderate speeds while instructing students.

Our rear brakes are like the front brakes except that the rotor has in internal drum for the parking brake.  This makes upgrades more difficult.

For a low cost and highly streetable solution we decided to go with what the Nissan factory picked as a high performance option for the Track Package 350Z, a set of used Brembo calipers that we bought from a local Z owner who had recently upgraded his brakes.  The Brembos are 4 piston front and 2 piston rear with the proper piston sizes and proportioning for the G35's master cylinder.  Unlike Brembo's racing calipers, OEM calipers have anti rattle provisions and dust seals for a long street service life.

Looking forwards to the more power element of things. The VQ seems to do allright with basic bolt-ons.

So close to my Coupe's Brembo setup with the lines from GregV, Motul, and EBC redstuff pads and EBC Ultimax Rotors. Better than new. Fantastic pedal feel and with a lot more tire than stock, traction to match the improved braking power. The crap Nissan put on the Brembos stock *shakes head*...

@ Fly'n_Z - past the intake/exhaust,etc. the JWT FW/Clutch, the plenum spacer mod and tune made a significant difference with my '04. Responds well to basic bolt-ons, seems to appreciate additional grounding, too. And dropping that 30+ lb dual mass FW for 11 lbs of JWT just woke that motor right up. But the stock ECU, that tune has to go - it just sucks up above about 5500-6000 rpm. Mine rocks and blows through 7k now with a real kick in the pants surge from 5k to around 6900-7000.

I may be wrong, but I question your wording that "Motul resists absorbing moisture from the atmosphere". All brake fluids (except silicon based DOT 5) are hydrophilic so that they intentionally absorb all water in the sealed brake system, thus preventing the water from corroding the lines or vaporizing at a low temperature. Not absorbing that water would be a bad thing.

Don't worry about it.

@Steve

– Sounds like my setup too on my 350. Although I feel a little envious that Mike's grocery getter is more hardcore that my car which I use on the track! I went with the cheaper DBA 4000 rotors in front and blanks on the rear. Your ECU tune sounds amazing, as is the engine doesn't reward revs.

It almost has the top-end happy of the '05-06 VQHR w/o the less impressive torque down low. I never had the plenum spacer alone pre-tune, so unsure how much that contributes to the upper end changes. Know what u mean, my '03 Z was all done by 6500.
