Brake Options

For some background, I've replaced my rotors once already at 20k miles and pads twice now at 40k miles. Meaning I've gone through 2 sets of rotors and 3 sets of pads. All on street driving. I have a stock car lowered on coilovers, this is my first "sports car", and I'm in my early 20s. Also, I blew the turbo on my fully stock car at 40k miles.

For pads I'm in between iSweep IS1500/IS2000 and Hawk HPS/Street 5.0. Anyone have any feedback on any of these? Also, does anyone know if the Hawk pads work for 2022 models? I know they changed the pin locations for late models and I haven't seen anyone mention anything about running Hawk pads on late 2022+ models.

As for rotors, it seems to be a lot more complicated. The options seem to be OEM/r1concepts/brakeperformance.com. I've read a lot about the differences between drilled/dimpled/slotted and I think I'm leaning towards dimpled and slotted because I don't want to risk cracking the rotors and having to replace them but I also want better cooling and the brake dust to be spread out of the rotors. The problem is R1concepts only offers drilled and slotted rotors and I'm afraid of them cracking. Can anyone support/contradict this based on what I've said. Am I just scared of a 1 off type of situation or is cracked drilled rotors a common thing? I'm also scared to go with brakeperformance.com as it looks like the construction of the rotor is different. From the images I've seen, stock oem rotors have two surfaces with veins connecting them. The rotors from brakeperformance look like it's a one piece and I'm afraid it may be too fragile for my style of driving.

As a side note, my style of driving is very aggressive and I want to get a set of rotors and pads that can take the abuse without having to replace them every 20k miles as in the past. I also want a slight upgrade in braking power over the stock 348mm brakes without having to switch to a $3k+ big brake kit. I've already dumped enough money in maintenance/mods to get a g80 into this car and I'm not looking to splurge a ton on braking for a sub 400hp car.

You mention you drive aggressive yet don’t want to replace parts at frequent intervals. That alone is a contradiction.
Even the highest quality of parts need higher frequency of replacement than standard oem.
Regarding pads, I’d recommend CSG endurance pads.
For rotors, OEM or the M performance big brake kit (dimpled).

I just saw the price of the CP compound and my mouth literally dropped. Almost $500 just for the front two pads. About $900+tax for all around. This is definitely out of my price range as I also need room to spend on the rotors. Any other good recommendations? What would be next up behind the CSG CP compound? Project mu?

I got a set of EBC reds and only installed the rears, as the front pins changed, and the performance is better than OEM but has me wanting more. I'm not willing to go all the way to CSG pricing but is there any options that would be a good upgrade over EBC reds that also have good resistance/durability?

As for the rotors, are there any other options? I've already gone through 3 sets of OEM rotors so I really don't want to go with that option again. Again, the M performance big brake kit is far out of my budget for what I'm willing to spend. Any other recommendations?

I’d recommend reviewing the brake pad thread that goes over options from all sorts of brands. Highly informative thread. Personally, I used the hawk HPS 5.0 for the street and we’re just fine before I switched over to CSG. I’d also recommend upgrading to SS Brake lines for a more firm and consistent pedal feel.

Most stick to the oem rotor. There isn’t really any cost effective rotor options. The only upgrades available are at a price point that is only justified if you are hardcore tracking the vehicle and need higher performance. Even so, most of us that track replace rotors with new oem.

I actually ended up getting the iSweep IS2000 pads and am planning on putting them on the same stock rotors I have now. It's hard for me to justify replacing them because the thickness is still a decent amount above the min spec and it would change from a $700 brake job to a $1700 brake job and at that point add in SS lines and change fluid and your 2k in. I just bled 2k for a stock turbo replacement so I need a few weeks to take a breather from that.

Min spec - 34.4
front right - 35
front left - 35.6

Min spec - 22.4
rear right - 22.9
rear left - 23.6


I'm thinking about getting SS lines anyways now and changing the fluid myself. I want fluid that will last a long time but still performs better than stock. From what I've read the recommendations are toward Motul RBF 600 dot 4 fluid but everyone says you have to change it every 6 months vs oem being every 2-3 years. Is there a balance of maybe something in between the two?

Yearly brake flushes should be adequate unless you're frequently tracking the car and heating up the brake fluid.
There's plenty of options for rotors if you decide you want to replace
https://www.turnermotorsport.com/BMW...KE+ROTOR+FRONT

Keep in mind the more aggressive your brake pads are the more they will wear your rotors. My car is at 27k with 3 track days and i'm just now looking at replacing the rotors due to minimum thickness.

Who is charging you $700 for pads and SS brake lines? That seems a bit high unless that includes parts and labor for all 4 corners(?)
As others have mentioned, there is no in between but yearly flushes are fine if you are not tracking your vehicle.

iSweep IS2000 front pad is $365. Rears were $200. Stainless steel lines were $200. $40 fluids. Thus you have a $800 brake job assuming you do the labor yourself.

Yep, makes sense. I forgot you decided to go through with isweep. The good news is once you move forward with this setup, the only maintenance for quite some time will only be flushing the upgraded brake fluid once a year.
