I'm planning on upgrading my brakes and I see the Brembo cross drilled and slotted for such a good price everywhere, but where should I buy the kit for the upgrade. It seems that everyone sells one, but which one is the best for street use, no track duty besides the drag strip about once every three months. I'm planning on doing the lines and shoes also, so if anyone has any ideas please forward pics and advice.

Thanks

 

are you planning to change it to a big brake kit of just the rotors....

 

You're not upgrading your brake rotors unless they get larger. Cross-drill them, slot them, it doesn't really solve any problems. Hence the term 'big brake kit'.

For stock-sized brakes, fresh fluid bleed, and more aggressive pads work pretty well. Stainless lines make for a crisper feel.

If you're not tracking the car, you'll never use the extra heat-dissipating capacity of a true brake upgrade. But if you choose to do it, be sure to make it a functional cosmetic improvement

 

I'm not looking at getting the big brake kit, just replacing the rotors, pads, and lines. I know that one of my front rotors is warped, so I might as well put on something better then stock. I like the look of the cross-drilled, slotted Brembo. Where would the best place be to purchase them?? I see that the RX7store has a kit for 589.00 but I also see that Gothem has zinc plated rotors for 129.00. Which one would be better for the street. It will never see an auto cross track.

 

For the street, get this package here:

They aren't drilled, just dimpled. They give the look of drilled rotors without the possibility of cracking like drilled rotors.

 

That's a really good package price! Wow. Cost me about $600 just for a set of 4 Brembo slotted rotors from Tirerack...and that was a decent price.

 

That's the point, there's nothing wrong with the stock setup for that use. Just buy whatever rotors appeal to you. Cross-drilled rotors will actually be a DOWNGRADE in braking performance (not stopping distance but heat capacity). For the street, this doesn't matter.

 

Hawk HPS and EBC Green brake pads are both good choices for the street. Stay far far away from Hawk HP+ for street use.

 

All I did on my mustang when I had it was upgrade to brembo cross-drilled rotors, and It was a HUGE difference in stopping power in combination with some hawk racing pads.....plus then you no longer have to worry about warping your rotors - they are worth the extra $$. =O)

Sorry, but you are wrong. The rotors did nothing to help stopping power. What you felt was the higher friction of the aftermarket brake pads. And rotors almost never warp. Read the FAQ in the Suspension forum or at Stoptech's website.

Cross-drilled rotors reduce the heat capacity of the rotor, as compared to a solid or slotted rotor. Under severe stress (aka track or extremely heavy street use), cross-drilled rotors crack at the drilled holes. This is well documented. Don't ask why Porsche or Ferrari use them (or even the new Z06 for that matter), it's a customer aesthetic issue guaranteed.

 

Trevor,

here is the thread that Rynberg is talking about. It's true what he said. Crossed drilled rotors negatively impact braking performance.

I bought a replacement brake kit and it came with the Hawk HPS pads. Whats the difference between the HPS and the HP+?

Im not tracking the car, basically just for normal daily driving.

 

Cross drilled rotors help with dissipating the gasses that are generated during braking and can glaze the rotor and pad and decrease the friction of them. They are widely used by Formula SAE cars, in which performance most definitely comes before aesthetics.

 

unfortunately, that is no longer true. Current brake pad compounds no longer out gas. Also, most race cars do not run cross drill rotors. You might want to read that link I posted...

otherwise the more experience guys will kinda tell you whats up with this

 

We came to a resolution on this. If you want to change rotors slotted is more than enough. Plus in any racing series there exists something called "sponsorships" that help to say "fund" the sport. If Brembo example sponsors a race team and 90% of their buyers demande drilled rotors what are they going to put on their cars?

I think the most relevant racing series to look at is the Japanese GT Championships. Notice the GT300 teams all use Slotted brakes even though manufacturers have the possibility of choosing one or the other.

I agree with previous statements that increased friction due to break pads is usually enough and say that if heat dissapation is a requirement than slotted rotors should be more then enough.

Joined our forum just to spit out data that hasn't been meaningful for two decades? Modern brake pads don't outgas. Cross-drilling rotors reduces their heat capacity, period. They are a performance DECREASE. End of story. Next.
