So I'm thinking about getting Brembo GT (black caliper) for my coupe. There is option for cross-drilled vented or slotted rotors? IS there a performance difference b/w the 2? Personally, I like the look of the drilled rotors, but are there advatnages/disadvantages b/w the 2. I guess the GT kit just covers the front and it is recommended to buy brembo rotors and pad for the rears (but using stock calipers). For equal cost, however, I think I could get a 4 piece stoptech or endless set?

What do u all think b/w drilled and slot rotors?http://www.hrpworld.com/index.cfm?fo...action=product

 

To answer your question,

Typically, drilled rotors have a higher tendency to crack than slotted when put under high stress. If you are just doing street driving, either will work.

The interesting thing is that based on those pt#'s, both the 332 and the 355 use the exact same caliper. http://www.brembo.com/NR/rdonlyres/9...eadingKey4.pdf
That would mean the 355mm kit has more brake torque than the 332. This isn't necessarily a good thing as the exact correct amount of brake torque is required to create a balanced braking system which minimizes stopping distances.

The comparable StopTech kits is considerably less. Our 332 kit is $1995 and the 355 kit is $2595. For about the same price as the brembo GT kit, you could get one of our 6 piston kits. When we move to a larger rotor or have more piston calipers, the piston sizes are reduced to accommodate for more leverage provided by the larger rotor, or for having more pistons.

 

^^Thx for your input. It seems the brembo gt kit is overpriced and not necessarily tuned for maximum brake performance. Could you please point me to a site/contact info to get moree information on comparable stoptech BBK's for my 05 g5 coupe? Thx!

 

unless you're tracking your car, you won't notice a big increase in performance. aftermarket bbk's essentially eliminate brake fade which you will not experience in daily driving. it's mostly for looks on daily drivers.

 

^^agreed. mostly for looks. But if I think the oem brake feel is kinda soft, even for my daily driving, is there a less expensive option (like just changing brake pads--or is that not recommended?)

Also, will most BBK's create substantial brake dust at the expense of minimal brake fade after extended braking use?

 

you can try getting stainless steel brake lines and new pads such as the hawk hps.

 

http://www.zeckhausen.com/Nissan/350Z.htm has probably one of the best descriptions of the big brake kit. He used to be a Brembo dealer as well. Our website is another great place for information. www.stoptech.com

Brake dust is primarily a function of the pads. In general, with performance(minimal fade and more aggressive bite) usually comes more brake dust.

Lower the amount of dust output and that brake pad will also have less performance. There might be some pads out there that can improve performance with less dust, however the performance will not the quit as high as those that output more dust.

A Stoptech BBK will stiffen the pedal quite a bit. All our BBK's come with our stainless lines that have a pvc plastic coating over the stainless steel to keep small debris from being working into the lines. I believe the goodridge lines that come with the Brembo's do not have this coating. The most flexible part of the entire brake system is usually the caliper itself. Under pressure the OE caliper will flex. By switching our that component to a much stiffer caliper, the brake pedal will become much firmer.

Yes, the primary reason for big brake kits is to increase heat capacity, but tertiary benefits include increased pad selection(since the pad shape is different from stock) as well as a faster reaction time of the brake system, meaning the time from constant motion to full deceleration is reduced.
