Hey, my car builds dust and swirls just like everyone else.





. . . you just have to look at it at the right angle from about six inches away to really see them. :lol:

well stated! i tried to polish all the swirl marks out of my car last weekend and gave up after i finished the dented hood. and still ended up spending 6 hours waxing. now that it's been a few days there's pollen and pitch all over it so i can't even dust it off.

I park outside in tahoe, with some work being down in the meadow to kick up extra dust. I only wash my car when i see some cheerleader car wash going on.

that and the Holh oil change + car wash for $22. (if you bring in your oil, and the filter is 13 anyways) what a bargain !

I have axxis ultimates and love them. The brake dust isn't as bad as everyone says. The dirt on the rest of my car keeps up with my wheels so I end up washing regularly anyway..

Yup, Axxis Ultimates front and rear.

Cool. What are your impressions so far?

no impressions yet, have to order them, then I'll install them.

As I'm seeking new pads for my 04 STi I thought I would post this reply from a guy that I contacted from the site. He seems knowledgeable.

See below.
*****


Heya..ok..pretty much Stoptech has a pretty wide line of option, but they
have a few things that just are not considered to be good pads anymore
(Axxis and Ferrodo)..and they have most of the world of good race pads
(PFC and Hawk), but are missing some new stuff on the retail market thats
been private labeled to NASCAR Busch and Nextel series for a # of
years...Raybestos.


Here is a list of relative strengths and weaknesses that I can answer to,
directly.

Hawk:
HPS, not as good as your stock pad for track use...but better than MOST
over the counter no-brand pads, and better than most non performance
minded OEM pads.

HP+, better than most any stock pad, but VERY dusty, and very agressive
HP+on
rotors. And for $350ish for a pair of front rotors for an STi, its a
terrible choice..and still not a good pure race pad, and its an iffy
street pad just because its so horrible on rotors.

HT10, a pretty darn good race only pad..no street use. Dusts enough to
want to clean it often, but -never ever- get it wet..clean it. HT10 dust
will damage your wheels, it'll stick to it and corrode to em. These will
cost a set of rotors per set of pads.

HT14, a more aggressive pad than the HT10, but too grabby most people
find...and worse on dust and rotor wear. But you shouldnt judge dust
levels on race pads, its what they all do when used hard.

PFC:

PFC01 is a better pad than HT10 by this much: <--> (two fingers close
together) in my personal expereience. Same rotor wear, and dust
characteristics as the HT10..dont let it stay long or get wet. Still eats
rotors.

Ferrodo:
I stopped selling all Ferrodo products about 2yrs ago, they changed
something in their pads..not sure what, but theyre not the old Ferrodo
that used to have a stellar name.

Pagid:

Pagid has some OK stuff in the full race Black, Yellow, and Grey pads, but
for the cost you can do better. Other than some stalwart old school
Porsche racers, I get no requests for this more than once or twice a year.
There is simply better to be had.

Axxis:
Friends dont let friends use Axxis. Are you my friend? :) Seriously, they
make a pad that feels nice and grippy at street temps, but they cannot
carry into track temps and retain good friction.

I dont trust any brake
manufacturer that gets defensive on the phone when you ask for
friction:temperaure charts. Axxis, EBC, and Carbotech are some of those
manufacturers. I try hard to be objective, but I take my cues by what I
see my customers, class members, and _competitors_ use on the racetracks.
Those are not seen there.



Here are two manufacturers not listed by Stoptech.

Porterfield:
PF has a few options for you, both for street+track use, or track use
only.

R-4S: This is their street pad that is capable of limited track use. In
an STi you have to give up some speed and agression to use this pad..its a
"hack" to put it best. You want a GOOD street pad that can take track
temps..the problem is the street manners of the pad means that the pad
shouldnt be hard on rotors. The R-4S compound is not. You MAY see up to
3 sets of pads on your car before you need to replace the rotors, and
generally you dont need to resurface between pads, the R4S pads dont
groove heavilly, you can add new pads and they'll bed in perfectly. Your
22k mile old stock pads probly have a good ridge of wear at the edge of
the rotors already. Once you turn those, you wont have much rotor left
before having to throw them away. So back on topic..to retain the
characteristics of a savvy street pad, the friction levels at high
temperatures just are not there. This compound is good to about 900d.
Thats some aggressive driving for sure, but not balls-out either.
And..the harder you are on them, the more they will dust, and the faster
they will consume themselves either. Its the nature of any performance
pads to wear faster as youdrive them closer to the edge of their
limitations. These are great front and rear...dont just do fronts, you'll
overwork them. You have to bring up the rear friction levels to match.

R-41: This is a cool new compound. It offers race frictions at street
temps. The chart in the aforementioned datasheets shows a wide temp
range, but the pad material starts to feel soft over about 600d, so its an
_ideal_ rear brake pad when you need more work out of the rears. If you
wanted a sweeet street only setup, Id go R-4S up front, and R-41 in the
rear. This should work OK on the track as well, Id like some feedback on
it if you do. Rally racers tend to like it because they can fine tune
their rear brake bias easier on it.

Race only options..

R-4: The original Porterfield race only pad. Pretty darn good, long
life, dust isnt severe, and rotor wear is still VERY friendly.

R-11: This is the new stuff this year. It has a killer friction and
temperature range, dusting isnt horrible, and the rotor wear is no worse
than the R-4. If you get into bombing speeds, I would also use this in
the rear. I would put these up against the HT10, and PFC01 race only pads
in a heartbeat, and I think this one's better.

Raybestos:

Raybestos has three options that are new to the public market. ST41,
ST42, and ST43. The only two that matter are ST41 and ST43 really. ST42
is good for low temp race use, and there are better options..but back to
the gooood stuff.

ST-41: You will not find a higher friction, higher energy, rotor FRIENDLY
pad to compare to this. These things are just..brutally efficient at
braking on the track. Dust is somewhat _low_, rotor wear is unusually
_low_, and they can take so much heat..that I am selling these in
situations where racers are bending the backing plates of other pads.
However, its only suggested to use these on the fronts of cars that have
either ABS, or very large race rubber with some downforce. Theyre wildly
awesome pads.

ST-43: If you dont have ABS, or need killer rear pads, these are the
perfect match to ST-41's in the front. They operate a tad colder for the
rear, and match the ST41 friction levels, they just do it more calmly and
slowly.



So..if you wanted a pad purchase that you can street & track knowing that
track use is going to compromise your top speeds (you'll have to drive
DOWN to meet the pad to keep it from wearing out too fast..in other words,
work on technique), I would use Porterfield R-4S in front and R-11 in the
rear. You could save a few bucks and use R-4S in the rear as well and
give up a tad more braking power.

If you wanted to swap street pads for brake pads..and I think that if you
try a hybrid street & track pad just once, you'll find it cheaper to swap,
I would use R-4S and R-11 for the street, and Raybestos ST41 and ST43 for
the track. If you swap tires, swappin pads only takes a few minutes to do
these as well once you have done it once.

I need to confirm the price of the Raybestos pads for the store, I had a
killer sale price at the Rim Of The World pro rally last weekend, so what
you see online SHOULD be correct, but if you can afford me the luxury to
double check, I would appreciate it.

I also have the Motul RBF600 fluid, and the Motul 5.1...the differences..

RBF: For severe use, can take very high temps. However, it -needs- to
move thru your system steadily. After every track weekend, flush out a
few ounces of fluid, about two dixie cups per corner..period. Its very
hygroscopic, and the heat abused fluid will float UP the system to the
master cylinder. :)

5.1: For long term street use. You dont need to flush like the RBF
requires you too. But cant take severe temps..also much cheaper.

And..FWIW, I could make SS lines for your car cheaper than the $165ish
that Stoptech wants, I just need to know length, and the fitting sizes,
should be exactly..or about..10x1mm threads on one or each end, and
possibly a banjo fitting on the other.


You race it..we brake it..

Dean 2006-09-04 10:15 PM

While I can't say for sure, that may well be Geoff from Speedtoys. Geoff is also on this board occasionally and resells a couple of manufacturers pads. He is very knowledgeable, but may tend to favor what he sells a little IMHO.

Don't have time to go through his post in detail, but right now, it appears the best back for your buck STI pads are the EBC compound of your choice. Matt just beat the heck out of a set of yellows at RFR and apparently likes them. I have had good results with both the greens, and reds in the past.

Axxis makes good cheep stuff for the street, and autocross, but it won't hold up on the track. Unless I am mistaken, Axxis = Bendix - AU. Dismissing them is like dismissing Ford, or GM. You may not like what they make, but they are none the less a force to be reckoned with.

What do you want the pads for? What type(s) of usage? That will narrow the field substantially.

Check out earlier in this thread as well as these two others for more info. Let us know how else we can help.

I like mine, have a better "feel" then the warn out stock pads. LOL

Is the dude on this forum right or wrong? He has brakes that are larger then stock and he thinks he can run in SP. I don't think I'm confussed as this guy and believe increasing the rotar size on my wagon would put me in SM.

It looks like if you are prepped to STX rules, you can run in the appropiate ESP class, but you can't mix and match between the rules solely to get bigger rotors. As in, if you have a different mod that is allowed in SP, but not STX AND have bigger rotors, then you have to go to Street Mod.

Joeyy 2006-10-03 05:21 PM

Well, I think I could run in STX. So, if I increased the size on my rotors or calipers for STX, I could then run in ESP with that set up. I really don't know why I'm in ESP and not STX but for the compeditors. I guess it's back to the small print on the rule book on line. I really need a copy for next year.

Do you have a reflash? Boost mods are not legal in STX, but brakes are. So you can run the big brakes in ESP if you're sticking to the STX rules and not running a boost map.

Kevin M 2006-10-03 06:24 PM

We (meaning me and Dean) went through this one a while back. Basically, if you have an ST-legal car, you can slap DOT r-compounds on it (or not) and go run in Street Prepared. The only additional allowance you get is that you can run any size tire, whereas AWD cars are limited to 245s in STX.

qksubi 2006-10-03 08:05 PM

Ferrodo products are my first choice! For the street 2500 and 3000 for the track also for the track I really like the hawk HT-14 but they are really hard on the rotor!

doubleurx 2006-10-03 09:19 PM

Washing your car too much makes it faster requiring better pads. Just stop washing your car and you'll be fine.

A slightly kinder alternative to the HT-14's are the Hawk DTC-70's. They're good up to 2000F if I remember correctly, and they're not as hard on the rotors. But they're not really at all streetable.

They are definitely race only pads. I never got a chance to try them on the yellow car before I left, but the Hawk engineering rep I talked to at SEMA last year said the DTC's were a much better pad than the HT series. They have better modulation at the limit, which is something we were never satisfied with using HT's.

The DTC-70's seemed to work just as good as the (soon to be discontinued) StopTech Club Race pads, except that they didn't overheat w/o brake ducts the way the CR's would. As far as modulation at the limit, I didn't really notice it too much, but ever since I switched to race tires, I don't think I'm braking 100% as hard as I could be for as long as I could be...

I looked back and found a modification thread. Dean was listing everyones modifications. With his red WRX he had in STX, he listed a STX legal map. I checked with COBB and they have a STX legal map. I'll have to get a turbo back to run the map but then on to the brakes.

I think the rest of my wagon is STX legal exept for my current ECU map. So now I should be able to look into some bigger rotors and better calipers and run in SP with a ST prepared car.

On the only bad note, a bigger rotor may not fit my current wheel. Dean had to give them up do to brake size. Time to open up the check book again.
