whats the difference between these 2? i want to get some cross drilled rotors on my track model z....would it be cost efficient to upgrade from the OEM brembo's to the big brake kit?


yes i used search.

 

since you already have the track brembos just upgrade the rotors much cheaper than the other route.

 

From my understanding Brembo only makes front BBKs for our cars. Brembo offers Grand Turismo BBK upgrades as well as Sport brake rotor upgrades for your existing OEM Brembos. The GT series BBKs are light weight 4-6-8 piston calipers with 1 piece or 2 piece "floating" vented rotors up to 15" in diameter. They are really nice but kind of $$$. Plus you won't have a matching rear set unless you paint the rears red/black or the GT BBKs factory Brembo gold.

 

Depends if you do a lot of tracking. More than likely, it won't be cost benefit for you to switch on a mainly street car.

 

Crosse drilled is an aesthetic upgrade only.

Upgrade pads if you feel you need more torque, not rotors.

 

well i plan on tracking the car maybe once or twice a month....as soon as i figure out how long a set of tires will last.

i do some aggressive driving in the hills, and have already experienced slight brake fade with the oem brembos...i want to get cross drilled (but not slotted) rotors, and possibly some better brake pads when the time comes to change them out. what do you guys reccomend i get? and whats the price range for just the rotors?

 

Cross drilled is the wrong way to go. Slotted is the better way.

 

really? i read that slotted rotors eat up the brake pads too quickly..whats so bad about drilled?

 

Drilled have a tendency to crack.

 

drilled can also increase the brake fade feeling

 

Plain rotors with appropriate pads are still the best choice when it comes to durability and maximum brake torque generation.

Centric makes plain replacement rotors for the Brembo Z. Get sportier pads if you have pad fade. Slots can help that, but pads wear much faster then.

 

+1

 

If you really want to get x-drilled rotors for a OEM Brembo equiped car, you should try out our two piece rotors.

The one piece rotors can't be drilled because of the pillar vane design which are posts between the friction walls.

 

So what, with the brembo brakes it takes like 30 min with a pair of pliers to change the pads.

 

I think most are concerned about price of replacing pads rather than install time...

 

I thought amplified brake torque comes from using a larger lever (larger diameter rotor)?

 

Yes you are right. But it might be difficult to fit a larger rotors on the existing caliper setup...

A higher friction coefficient (μ) or more clamping force will increase braque torque too.

The easiest and cheapest way in our case is to mount different pads.

 

But, aside form the cheapest and easiest, is the braking performance that will be seen by upgrading to a Big Brake Kit with higher coeffecient pads vs. the OEM Brembo kit with higher coeffecient pads validate the price difference between the two?

 

Good question. The answer will be dependent on personal tastes. Ultimately, tires and suspension is what will slow you down. Any brake system that can overpower your grip will be sufficient. The Brembo setup coupled with proper race pads works very well. To give you an idea, most guys I know how track their Brembo equipped Z do not upgrade to a BBK.

Personally, I don't think that the cost of the BBK is worth it over keeping an already existing Brembo setup. I put my money on track time, tires and suspension bits. Plus, a larger BBK will be more susceptible to pad knock back.

If upgrading from the "regular" brakes though, I'd go with a different BBK. StopTech and AP come to mind. Others might be good, but I haven't researched them.

 

Have you guys tried Axxis ULT pads in the Brembo's? I think they are very reasonable priced.
Front retail, ~$50
Rear retail, ~`$66

I have no idea why the rears are more expensive. Probably not as commonly produced.
