If you've been wondering if the iSweep pads really throw less dust & just how much less than OEM...

Here are pics of a front wheel and a rear wheel after 4 weeks since last wash & about 800 mi.

Not only is there FAR less dust, the iSweeps' dust is just not as "clingy" as OEM. Wheels stay cleaner and are much easier to clean. Just a hose-off is all it takes to remove most of the dust build up.

The brighter wheel is the front wheel - it is exposed to the overhead lights more than the rear.

This ain't the only advantage of the iSweeps - they are also far quieter. Grab is at least as good as OEM, too.

i recently installed my isweep 1500 and the brake dust is night and day. after the new pads and several weeks of driving my car looks dirtier than my wheels. pretty amazing stuff

but i don’t believe the pads perform anything like the oem pads. Initial bite is completely different and would say the lack of bite. brake feel is much different

it feels like i have lost confidence in the brakes. i have a upcoming track day and thinking to switch back to oem pads.

maybe just my perspective but i question if the reduction of brake dust is worth the reduction in braking power.

Ehloo How intense of a track day? Most people do NOT recommend using OEM pads for track days, as you will wear through 1/3 to 1/2 of the pad (or more, people say) in 1 track day.

The OEM pads have a temperature rating of "G-G" which is why they have very good cold, and hot, bite. However, they are not built for extended high temp (or extremely high temps). You may want to consider a dedicated track pad if you want more than 1 or 2 track days out of a set of pads.

There is multiple threads on track day pads, and temperature rating of the OEM pads (most aftermarket pads have not been validated by the same testing procedure, so you cannot directly compare the temperature based coefficient of friction).

I'm only relaying info I have read on here (and data I reviewed for the testing procedures for friction ratings), as I only have 400 miles on my car and 0 track days so far.

[Ehloo]

i do maybe 1-2 track days a year and i wouldn’t say it’s intensive. my point if anything was i feel the stock pads actually perform better than the isweep1500.

i wanted to provide my feedback as it seemed much different than others which made ultimately make the decision to purchase the isweep’s

the brake dust improvement is dramatic, no brake noise. but i have to say there is a large trade off for those improvements. most reviews will say there is minimal or no difference in brake performance but do not agree with that all after a couple hundred miles.

i wanted to shed some light on the performance aspects as everyone concentrates on the dust and noise benefits.

maybe the isweep 2000 would of been a better option for me

Maybe I didn't spend enough time on the OEM pads to really evaluate any differences (?) I did swap the pads pretty soon into ownership. Yes I did notice a reduction in that initial grab but I liked they weren't as grabby at first press. I have had some butt-licks cut me off on 91a & have had emergency braking situations and all went well, thankfully. Thay the OEMs have even more stopping power, that would indeed be impressive!!

I'm like you, I only track a few times a year (nothing this year). And I am not a track monster - I love the autocross tracks more than the big tracks. I will get a track pad because I know the iSweep 1500s are not for track use.

I'm curious to see how the iSweeps perform in the CT cold.

[aerobod]

Going by this iSweep friction curve for each of their pads, the iSweep 1500s are likely FF or FE rated, the 2000 & 2500s FF rated (just under GG, though) and the 3000s GG rated, but without actually completing the J866 test regime, it can't be known for certain. ISweep also have some generic OEM pad friction curve in their chart that bears no relationship to the G87 GG rated pads, but is more likely a standard OEM pad fitted by most manufacturers to their average vehicle.

Its been mentioned on the G80 forum that 1500's are really designed for street use only.

I had the 2500's on my G80 and they felt just the same as stock to me. But where SILENT as a mouse. I guess the 1500's produce even less dust than the 2500's. But I could go a week without my wheels turning another color. I think it was mentioned that those who track or auto X should get the 3500's.

I will be getting the 2500's again for my M2 which I do no track. The brake dust reduction was massive enough for me with 2500's.

[Ehloo]

i didn’t even consider the 2500 as everyone said the 1500 were like stock. the reduction of brake dust on the 1500 is so dramatic and almost like there is no dust. i would drive 10 miles on oem pads and my wheels would be a different color. after 100 miles on the 1500 you can’t even tell there isn’t any dust.

makes you think how they do that. assuming much less friction

I'm am glad I saw this thread. I'm a newb when it comes to these types of things so have a quick question.

When you guys are swapping out the break pads to the iSweeps are you also swapping out the rotors as well? Is this something that is required? I was hoping to swap them out as soon as I can but if I am not able to swap them out right away would that cause some issues?

Also, are you guys buying the break wear sensors?

Thanks!

No, you rarely need to replace rotors when swapping pads. Maybe at 80,000 miles but certainly not when new.

Thanks for the quick reply! What is meant when people say "bedding"? Also, should I buy the brake sensors when buying the iSweep pads?

It is worth having spare sensors (one on each axle), as sometimes they can be damaged when the clip is removed from the pad, but just reuse them if you remove off the OEM pads successfully and keep the new ones as spares.

Bedding is matching the pad surface to the rotor surface, the procedure varies depending on pad type and manufacturer. Sometimes it is just driving gently for a few hundred km/miles, sometimes it is getting them up to the fade point and driving around to cool them down. The pads should come with bedding instructions.

Only buy the sensors if you’re clumsy and feel you may break one. I’m clumsy and did not, so…

You will want to have a thin 17mm wrench for the rear calipers. I bought these:

1500s are incredible. Feel same as stock to me and love the decrease in dust! Especially on silver wheels!!

I was going to have my indie do the work. I would hope they wouldn’t be so clumsy.

It really is super easy, if you feel like handing in your own. I wouldn’t call myself ‘handy’ in working on cars and this was an easy job.

I have over 5k miles on my iSweep 2000 and agree with you. The braking power feels so different from OEM. The car will stop, absolutely, but is not as dramatic. Be warmed the brake dust is way more than the 1500s but less than OEM. After 200 miles they look dirty but black, not cinammon. I would bet you would be dissapointed with the 2000s.

My car was very brand new when I swapped the pads, rotors had next to no wear. You shouldn't need to replace the rotors unless they're deeply scored or gouged - which you'd have to do anyway even if you didn't replace the pads.

[Ehloo]

guess nothing is perfect. they state the 2500 are 50% less dust and 1500 80%.

questioning the benefits of the reduced dust versus performance. it doesn’t feel like M brakes anymore

Agree! There will always be tradeoffs. I spent a few months thinking on going back to oems but could not convince myself to go back to the cinammon wheels… after that, I guess I got used to the 2000s… havent tought about it much lately. Whenever is time to replace them I will look up at other options.
