I wondered how the ceramics might be bedded in so I asked iSweep, and got this back:

“For iSWEEP, there aren’t really any special methods for bedding in the brake pads. If the customer drives for 3-600 miles on a regular basis, then it will naturally become bedded in.

We have had some issues with customers performing the traditional bed-in methods which we strongly believe that our non-metallic compounds do not require.

So if the install is done correctly and properly, they should be good to go. “

Good to know I can just drive and that’s it!

It is a simple as the compound composition.
It will not stand the heat temperature for track usage. Hence track guys always uses a track specific pads where it dust and squeal way more than any car manufacturers stock pads.

I wish they could tell us more details about some of these non-metallic compounds.

Wait, WHAT?? Does your car cheat physics?

Maybe because the rear pads are 3x smaller than the fronts they get eaten up faster?

...what? What does "X brakes get used more than Y brakes" have anything to do with physics? I'm talking about more dust being visible, not "given the same amount of usage the dust is more on one than the other"

You wrote: the rear brakes get used more than the front. Not sure how else I was supposed to interpret that.

You have a car that already has more than 50% of it's weight on the front wheels, and when you brake, you transfer weight forward. I'm sure I'm not telling you anything you don't already know. You know, momentum, moment of inertia, central axis of rotation and all of that.

So given that, not sure where you were coming from when you said your rear brakes get used more than the front. Unless you were trying to say that your rear brakes are worn down faster then than the front since they are smaller? But it's physically impossible for them to do more work.

You realize that not all 4 brakes can be/are used when you press the pedal right? It's not an equal pressure applied from the system, as far as I've read, which is why the rears wear faster. At the very least, TC and stability control will utilize the rear breaks *specifically* for its functions, leading to more use on the rear brakes.

Of course. But TC/Stability control would be the only way the rear brakes would be used more than the fronts. By a country mile, because, as I said, physics. So unless you're getting those systems to activate a lot, the front brakes are always going to be doing way more work.

As for what you've read, those who have toasted the rear pads on track have said they are running systems off, negating that point. Which leads to one of two conclusions. Either "systems off" on the dash does not truly mean systems off, and the car is still using rear brakes for torque vectoring or stability control or second that the stock pads are so small that even though the rear brakes are doing far less work than the fronts, the fronts have more ability to absorb heat because they are so much larger than the rears, and the rears just disintegrate.

I'm honestly leaning toward a combination of the two, more so the latter than the former but without monitoring the braking system during track use, I don't think we'll actually know. Either way, it's a problem...the rear brakes are not up to the task they're given, which is a shame.

iSWEEP IS2000 installed and loving them so far. Zero noise and took five days instead of one day to notice brake dust on my black 826M wheels. Very happy!

I just installed mine. First brake job in a while - I have 5k miles and I didn't have to spread the pistons at all which was nice.

The hardest part was removing the wear sensor (I wasn't sure on how that connected). I ended up disconnecting it when the pad was completely removed just to be safe. And then of course, trying to get the caliper and pads back on the rotor took a little finagling but wasn't too bad.

A small bit of the red caliper coating seemed to chip off the back of the caliper which was annoying. Right near one of the pad pins. I'm not sure what caused that.

Anyway, haven't driven a ton, but initially the grippiness seems a little lessened, but the pedal feel is good. And - SO QUIET

I do hope they hold up for some spirited driving and a novice track day.

Do you all have a lead on who has these in stock? I wanted to order these sooner than later.

I bought the 1500's, I have about 500 miles on them know.....I absolutely love them. They brake great, and almost 0 brake dust....wow.

[christianb5s4]

Just ordered the is2000s from RG who confirmed they have stock. FYI for anyone else interested.

Hi all,

I’ve decided that since I was the guinea pig here with the IS pads, I’m going to ask all of you to donate me each $100. So far as r33_RGSport I think it’s only fair and the right thing for you to do is a little kickback as well.

Otherwise if none of you are up for it, enjoying these pads as much as I have is good enough 👍

Now you've all got me thinking. How different is the amount of dust on the 1500 vs 2000? Also I assume both of them are silent, squeal-wise.

I imagine it's more, but is it a lot more that if you don't plan on tracking the car, you wouldn't even consider it?

I would say about 10-15% more.

I've had both. The 1500s are about a 95% reduction over stock. It's a massive difference. The 2000s are probably about a 60-70% reduction over stock. After about 100 miles of road driving on the 2000s the brake dust is noticeable, but not nearly as bad as the stock pads.

With the 1500s I didn't even need to use Sonax, just soap and water and it pretty much took care of it. With the 2000s I have to use Sonax probably every other weekly wash, and the wheels come out pretty much clean without having to agitate the Sonax (to get them truly clean you'll need to agitate).

I've had no issues with any kind of noise from either set.

Braking power, IMO is much better with the 2000s over the 1500s on the street. I have not tracked either set. I upgraded to the 2000s because I am planning on doing some track days, but also because I was not happy with the stopping power of the 1500s on the road. YMMV on that though.
