yea, my bad - sorry about that...


i'll keep that in mind next time i'm cruising the autobahn at around 180 mph or so... which brake setup would you rather have..?

here's an excerpt from stop-tech's website - just an FYI:

"Why do I need a big brake upgrade?"

Modern stock brake systems, for the most part, work well for a single 60-0 or 80-0 stop, and average daily street driving. The typical performance enthusiast will quickly push the stock brake system beyond its capabilities.
Driving style and other performance modifications such as increased horsepower, tire and suspension upgrades quickly add up to overpowering stock brakes. A big brake kit will provide increased heat capacity, which means substantially more resistance to brake fade and caliper distortion with multiple stops from high speed. A firmer pedal due to stronger and stiffer components, as well as better modulation characteristics under threshold braking are also typical with a properly balanced brake upgrade.

 

Not buying a car because of the brakes is crazy.

 

Don't consider myself crazy at at all. The stock OEM Nissan brakes just had no feel and were to grabby for me. Why buy something I don't like? The Brembos are a great asset to my car, and influenced my decision. In other words, they pushed me over the edge to get the 6MT Coupe. If they weren't there, I would have held on to my old car, and bought something else latter on.

If Nissan wants to dump the Brembos thats their decision, but to blame it on performance issues just isn't right. They should just come right out and say its all about the $$. I totally agree with Lou about the grabby stock brakes. Every time I get a loaner I almost put myself through the windshield because there is no feedback and then all of a sudden they catch hard. Also, I just considered the Brembos icing on the cake. A base 6MT with Brembos/leather for $32.5k was an awesome value. While I wouldn't pass this car up if it didn't have Brembos, if I were buying soon I would jump on a 04 ASAP.

 

One of the main reasons I was considering the 6MT coupe was for the Brembos. I will likely never take the car to a track, but love the look.

To me, the Brembos are just like getting a new set of rims. The rims will likely improve the appearance, but not the performance. Love the looks!

 

everytime i'm at a stop, i look at the next car next to me, and i'll catch the driver looking at my Brembo's all the time. just today, this woman had a base coupe, coudn't tell if it was leather or not, but she has the 17"s, and i even caught her checking out the Brembo's. plus, everytime you see brembo's it reminds you of all those exotic cars because thats what most, if not all of them uses. didn't nissan had thier own 4 piston front, 2 piston rear setup like the 300ZX's had? i wouldn't think it be that hard for them to come up with a almost look alike setup..

 

i think if you measure 60-0 distance after few round on the track, you will appreciate the brembo. but i would agree that for a grandpa driving on the street, they are no more than the name.

 

johnny, i get that too, when im at a stoplight or something i always catch someone looking at my brembos. =)

 

thanks but i was looking for the G35 one..

 

Why is the Z still have Brembos even when they said its causing problems. They even add it to the conv as a option. I think its rather odd.

 

The Special Anniversary Edition "Z" has 'em. Real 4 Pot Brembos. Tsk Tsk Infiniti.

Actually, G35_TX, its not the PADs that prevent fade. A grippy pad will significantly improve the stopping distances of a car and better lines will improve response. However, if a person wants to prevent fade, he or she would need new rotors and preferably more pistons in calipers. I say this because fade is the result of a car's inability to dissapate heat when the repeatedly being subjected to hard stops. While a better pad MIGHT help, it also might not get heated up sufficiently to work well on the street in the case of this hypothetical pad.

I do think those people who get big brake kits with 8 pistons and 15 inch rotors, who think they are getting better braking power are crazy unless they drive a dedicated track car with at least 450 hp. I'd say these show almost no improvement versus say a 4 piston setup on the street and light tracking and also that really, it would just slow the car down due to added rotating mass.

I'd say the stock Brembos are pretty nice, although they dont seen to perform as well as the stock brembos on the EVO.

 

Yeah the Evo brembos lead the car to stop from 60 in 100ft that like the best ever for a sedan let alone a stock factory car.

 

yeah..
when comes to brake distance...
it dosen't metter if the brake is 2 ,4 6, 8, 12 or more pistons
it will stop almost the same distances
on the same car..
to have more port is to prevent fade on track for 10 to 15 plus laps

so...TX when u say autoX or track...
how long did u run ur car on the track..to notice the difference?
don't even talk getting fade on an autoX..!

 

Brembos on the roadster? You sure? Sorry for being thick, but I did not remember reading that.

 

I believe it, but why are the Brembo's better? Do they deliver more force? More reliable force? Better cooling? Bigger brake surface? Is it the multiple pistons? Or are they more durable?

Back up the claims. If the Brembo's are better tell us why.

I wonder if one of the pad manufacturers has done a comparison? Setup two identically equipped G's or Z's and use identical braking pad compounds and brake fluids. Switch the calipers and see which caliper does better.

This is probably one of those things, you can spend the big bucks on great caplipers, and then blow it with cheap pads or fluids or lines.

If you want better stopping you have to go all the way. Brembo's with Axxis pads, Stainless lines, and premium fluids, and don't forget the rotors. Go all out and get a better cylinder and the damn thing will stop on a dime, heck half a dime. Skip one of the parts, and you run the risk of fade or slagging the pads. Then you are just praying for a nice straight piece of road to coast to a stop on.

 

So if I upgrade the brake lines to better ones for the standard brakes will that do anything to improve it?

 

I wouldn't dare go out on the track with the stock (non-brembo) setup. I've been to track days where non-Track model owners completely toasted their brakes after a couple 25 minute sessions (and many of them even had upgraded pads and lines). The stock rotors and calipers were just not designed for any sort of track use. The Brembo setup on the Track model is much more suited for the track. It can take a lot more on the track without complaining. I would recommend upgrading the pads to higher performance ones even on the Track model Brembos though. The stock pads will carbonize too much at the kinds of temperatures you see out on the track.

But even the Track model (heck, even the big aftermarket ones) has it's limits--you still have to be careful with your braking to prevent it from meltdown. Afterall, the Zs weigh 3200+lbs. (and who knows how much you fat @$$es weigh). If you are planning on seriously racing your cars, you'll have to trim the weight of the car significantly. *sigh, this car would be so much better if it weighed a bit less...*

 

I've been reading this thread w/ some amusement. I am not a braking expert, but the point about brake fade on the stock v. Brembos can't go unexplained and no one has managed to discuss it yet..

Brake fade is a function of several things. First, fluid. Boil the fluid and you trap air in the lines and you get brake fade. Not likely to happen under most reasonable street conditions. Will occur at the track and under abusive street conditions. That's why racers bleed brakes every race weekend. Second, choice of compound is a factor. Hawk Blues need HEAT to work properly. So, they are not suitable for the street. But at some point, all pads can no longer absorb any more energy. And when they can't absorb energy, you get fade. Third, the types of rotors used also affect fade. Whether or not they are vented and/or ducted and the material. If the pad has absorbed all the heat they can, and the rotor has done the same, brake fade. The heat is no longer absorbed by these two surfaces and the heat disipates up into the fluid, which results in the aforementioned fade.

The Brembos are a different design than the stock rotors. The Brembos are 4 pot, opposing piston design. So, you have two pistons on each side of the rotor pushing onto the rotor to stop the car. This is a racing design and one that is preferred, but it costs more and has more moving parts. It is a better design because the braking force is more evenly distributed along the four pistons, on two sides of the rotor.

The stock G35/Z rotors are a sliding design w/ pistons only on the inside surface. When you hit the brakes, the pistons push from the inside and essentially pulls the outside pad to the rotor. Nothing, other than the caliper braket is acting on the outside of the rotor.

So, without a doubt, the Brembo design is a much better design.
