Is there a big difference in the brakes between the Brembos from the Track model to the standard breaks from the Base/Enthusiast/Perf./Tour ??? I say this because the the G35 sedan stopped from 60 in 114 ft. while the coupe with brembos stopped only 1 foot less at 113 ft. Anyone know the numbers of stopping distances between the Track vs. other models. Also is stopping distances hte only difference between the brakes???

 

I have the track but havn't driven any other model. The magazines basicly say that the brembos don't reduce stopping distance but are very fade resistant. In other words, after 5 hard stops from 60, the brembos will still be working at full capicity, the standard brakes will be taking longer to stop.

 

Braking distance in modern vehicles is dictated by tire performance, not brakes.

There's your answer.

phl 1002, please explain your tire theory on braking distances, Im curious

 

Light weight wheels make a HUGE difference. when talking about wheels you are dealing with rotational mass, not standing weight. It works out that 10 pounds of rotational mass is equivalent to 50 pounds of standing weight. So if one set of wheels weighs 30 pounds and another set of wheels only weighs 20, you aren't shaving 40 pounds of weight, you are in actuality shaving 200 pounds.

 

I believe what phl 1002 is referring to is the coefficient of friciton between the tires and the surface it sits on. It appears to be true that braking distance is dictated largely by the tire make up. Thus high performance tires will have better braking distance than "every day" tires due to the better compumd make up of the rubber, taking into account the same brake set up. There was an interesting article that explained this in more details in SCC.

 

The best tire in the world will not stop correctly without the right size rotors and pads. If you put a 9 " rotor with the same relative size pads on a Z I would not do 140 mph in the car and expect to stop very fast. Tires and brakes work together, they need each other and have to sized right to work correctly.

 

Agreed, that's why I said given the same brake set up, the higher performing tires will stop better than "everyday" tires.

 

tpfalkowski:

Obviously, if the brakes are underspeced the car won't stop as it should. However, brakes on production vehicles far outperform any street tires in terms of stopping performance.

Possibly, the brakes on the Z wouldn't be able to lock up the wheels with racing slicks at the proper operating temperature but I seriously doubt that.

The only way to improve absolute stopping distance with this vehicle is to improve its tires.

The Brembos won't fade, that's why they cost more.
