Wow, those Brembo Rotors are expensive$2000 for a set of four, I hope they last a bit.

Great read, pretty much cemeted what I suspected all along.

The stopping distances are basically the same ,except the Brembo package will offer more fade resistance.(and it looks real cool:drooling)

And that's WITHOUT the Brembo brakes and bigger rotors!

yes, the only advantage the Brembos offer is greater fade resistance ,as they cant improve on those stopping numbers.

Sure they could. Put on stickier tires.

Nice read that until multiple [6-8] 100 mph stops there was no difference in stopping distances.

The 90-96 Q front pressure at the breakpoint is 1067 psi when rear is 750+ and C caliper deflection might be 3-4 times more than a good 4 piston set up say 75-100/1,000th vs 25/1,000th.

Steel has a very bad coefficient of friction worse than cast iron rotors."Asperities, which are microscopic projections from the "average surface," play a major role in determining the coefficient of friction between materials. The friction depends on the asperities of the surfaces in contact. The pressure on an asperity is greater than the normal force, that it may deform the contact area "plastically" (asperities can weld together). Therefore, frictional resistance arises from sliding objects breaking and creating bonds created by asperities. "

The Brembo greater thickness means the walls of the rotor are thicker by at least 25% each and so is the venting air space! This probably doubles the mileage to warping.

With grippier tires [than the Pilots] the ABS would need to be reprogrammed to get below 100 feet [60 to zero].

The[tire/road friction coefficient would need to go to 1.21 vs 1.08 currently.http://hyperphysics.phy-astr.g....html

Keep in mind the G35 SEDAN stops from 60 mph in 111 feet (3 feet shorter than the 2004 Z-06).

And that's WITHOUT the Brembo brakes and bigger rotors!

And really soft pads (softer than what's already on there, which would be roughly the equivalent of steel wool...)

If members would tolerate 1500-2,000 mile street tire life a G or Z could be made to stop in 83-85 feet from 60 mph.

NB 1995 Williams Formula One 100km/h in 16.1 metres. = 53 FEET

Great information as always Q45Tech. Thanks.

dang, 53 feet...

As mentioned many of times, it's not just the brakes that stop the car. The tires play a BIG role in stoping the car. It doesn't matter if you got the best brake package in the world unless you've got the tires to back it up.The thing w/ the brembo package isn't that it stops the car quicker, it stops it quick REPEATEDLY, w/o fade. This also means that later, if you wanted to upgrade, all you'd have to do would be to change out the pads. Whereas w/ the regular brakes, you'd have to spend an ungodly amount of money on upgrading the calipers and rotors.
