Stoptech lines have a molded plastic reinforcement around the end fittings that reduces the fatigue of the line in this area, allowing the passing of the whip test with ease. We also noted the quality of the fittings and the superior fit of the Stoptech parts in general. This is a welcome change after many years of jury rigging most braided brake line kits with zip ties, Adel clamps and other devices to get a safe fitment. It is refreshing that the Stoptech lines simply slide right in with no hassles or fiddling around.

Last in line for our brake upgrades we replaced our stock, stale never been changed before Japanese fish oil brake fluid with Motul RBF 660. Motul’s RBF formula is one of the best fluids, performing nearly as well as or better than uber expensive exotic stuff like the legendary F-1 brake fluid standards Castrol SRF and AP650. When brake fluid gets really hot it boils. Boiling fluid has bubbles in it that are filled with compressible gas. The compressible gas causes the brake pedal to drop to the floor. This is another type of brake fade that must be avoided.

Motul’s dry boiling point is an amazing 617 degrees F with a wet boiling point of 400 degrees. Motul works so well that our teams race cars need only bleed the brakes once a season, instead of the typical once a race. Most brake fluids absorb moisture from the atmosphere. When the brake fluid absorbs moisture its boiling point rapidly drops rendering it less effective. Even though the brake fluid is contained within the brake system, it still can quickly absorb a surprising amount of moisture from the atmosphere that is inadvertently drawn into the brake system.
Some brake fluids can deteriorate greatly from this phenomenon with as little as one heat cycle of the brake system. Motul resists absorbing moisture from the atmosphere better than most brake fluids so its inherently high boiling point lasts longer than most fluids. If you do manage to boil Motul, surfactants in the formula cause the bubbles formed to rapidly dissipate and you get a recovery of your brake pedal feel.
The brakes on our G35 feel much better. The brake pedal is firm and confidence inspiring. The brakes have good initial bite and a low pedal effort. They are also quiet and squeak free like, well stock brakes. We have yet to revisit the track but we know that the brakes will perform much better than stock and with a pad change, very well. Most of all since our Rays wheels have such a large open area, the Brembos and DBA rotors look much better than stock! The fact that we did not have to spend much money to get this level of performance is even better.
Stay tuned, in future segments of Project G35 we will work to get more power from the engine.
