Default Anything between Hawk hps and HP+

Pretty simple street brake setup question:

-I installed some hawk HP+ 2 years ago.I totally liked the feel and the grip of those pads.But they where noisy has hell (even after a lot of bedding session) and of course they did produce a lot of brake dust.

-I then installed some hawk hps last year.I totally liked that they where low brake dust and they didnt produce any noise(100% quiet).But damn again even after some bedding session i didnt like the feel of the pads.Seems to slip instead of gripping...

What pads would you recommand for heavy spirited street setup that would be close to the HP+ without the crazy noise.

Already running some Powerslot rotors and got some braided brake lines.
Thanks

I've had good success with EBC pads. Have a look at the Redstuff and Bluestuff

Nope. I like the HPS for the street.

If they don't feel like they're gripping you may have overheated them and created too thick of a transfer layer on the rotor surface. You can try cleaning the surface of the rotors with brake cleaner and using a medium grit sandpaper to get the transfer layer off. I usually like to lightly scuff the pads as well. Then again, maybe you're just expecting too much of them compared to the HP+. (I'm not really a fan of the HP+ but that's a separate issue.)

Reds are nice but they take a little longer to grip then the greens. But I always felt the greens never gripped hard enough

axxis ultimates use to be but they are no longer made by PBR

the stoptech streets are very similar to the HPS but have a higher temp friction co efficient, in short they wont fade as fast but they don't have the bite of an hp+

if carbotech wasn't priced so high it would be fun to try some of their pads to see where they fit in

I just bought a set of Carbotech XP10's for my daily driver and I hope they will be even better than HP+'s with similar warm-up characteristics. I havent installed them yet, but will let you all know how they work...

The XP10 will make some noise on the street but will shine on a road course, if you are not tracking the car I would go with XP8 front and 1521 rear. When using Carbotech XP series pads the pre bed option is highly recommended, they have seen better wear and less noise.

Honestly, we run Hawk performance ceramics on most of our stuff and don't have any issues.

Well i dont have issue with the quality of the product and no its not a problem of disc or anything else.I also switch my HPS back to my hp+ and damn do i like the initial bite of those pads but cannot stand the squealing noise.

So my option would be some XP8 ?
But why only in the front ???
The bobcat 1521 and hawk ceramic have zero initial bites...
I gotta go read on this .

Most of the braking is done in the front. So, anything higher than 1521 in rear will not work properly because you will not generate a enough heat on the street, unless you go to the AX6 in the rear which tends to be noisier and dustier than the XP8.

Carbotech™ 1521™

The Carbotech™ 1521™ is our high performance street compound. The 1521™ compound is known for its release and modulation, along with unmatched rotor friendliness. 1521™ is also a very low dusting and low noise compound with an excellent initial bite. This compound's excellent linear torque production provides incredible braking force without ABS intervention. Carbotech™ 1521™ operating range starts out at ambient and goes up to 800°F (426°C+). 1521™ is suitable for ALL street cars, perfect for your tow vehicle or fleet vehicle. Carbotech™ 1521™ is NOT recommended for ANY track use.


Carbotech™ AX6™

The AX6™ is specifically engineered for Autocross applications. A high torque brake compound delivering reliable and consistent performance over a very wide operating temperature range of 50°F to 1000°F + (10°C to 537°C+). The advanced compound matrix provides an excellent initial bite, high coefficient of friction at lower temperatures along with very progressive brake modulation and release characteristics. Many drivers use the AX6™ for street driving as well, even though Carbotech™ doesn't recommend street driving with AX6™ due to possible elevated levels of dust and noise. AX6™ is NOT recommended as a race compound in most applications.


Carbotech™ XP8™

A high torque brake compound with a wide operating temperature range of 200°F-1250°F+ (93°C to 676°C+). Carbotech™ XP8™ is the first of our racing compounds. Good initial bite at race temperatures, high coefficient of friction, excellent modulation and release characteristics. Extremely high fade resistance and very rotor friendly. Perfect for track day use with any tire and can still be driven safely to and from the track. Carbotech™ does NOT recommended XP8™ as a daily driven street pad due to elevated levels of dust and noise. Carbotech™ XP8™ is a great compound on the front & rear of most open wheel and sports racers.

Every pad rotor combo are different, I can not say the noise will be less but, the performance will be a huge step up. If you start the XP8 on new rotors and pre bed option I think you will have no issue wants pad is at temp, Driving on the street with a race pad your going to have noise. A race pad is designed to work at optimal temperatures. Only Carbotech uses a 100% non corrosive compound so, it will not harm your wheels or paint

Default '03 63k miles due for pads and rotors, what to use?

I just purchased my last Corvette, an '03 with 63k miles. Pads are due for a change, rotors too I guess. Street driven, no track and not a hard driver anymore - I use motorcycles for thrills. What would you recommend, install all the stock GM parts from gmpartshouse? Thanks!

if you want low low dusting and a long pad life the hawk ceramics are a pretty solid choice

or stock,

either one would meet your needs really well

For those pads you will need a lot more than 4 coins.

Take a look at the Carbotech 1521 pad.

Carbotech™ Bobcat 1521™ The Carbotech Bobcat 1521™ is our high performance street compound that is our most successful compound. The Bobcat compound is known for its awesome release and modulation, along with unmatched rotor friendliness. Like our AX™ & XP™ line of compounds, Bobcat 1521™ is a Ceramic based friction material offering minimal rotor damage and non-corrosive dust. Bobcat 1521™ offers outstanding performance, even when cold, low dusting and low noise with an excellent initial bite. This compound’s virtually perfect linear torque production provides incredible braking force without ABS intervention. Bobcat 1521™ operating range starts out at ambient and goes up to 900°F. Bobcat 1521™ is suitable for ALL street cars, perfect for your tow vehicle, police cruiser. The Bobcat 1521™ compound has been found to last two-three times longer than OE pads you can purchase at a dealership or national retailer. That’s one of the beauties of Carbotech Ceramic brake compounds. Bobcat 1521™ is NOT recommended for any track use.

thanks for the feedback - I'll be replacing the MSRC shocks, rotors and pads soon.
