Massive X5M Brake Upgrade Coming

rcsup1 · 06-18-2019, 11:14 PM

After seeing the innovation hardparker did on the X5/X6 brake upgrade I decided to take it to the next level.

I purchased X5M Calipers with brake pads on ebay but then ran into an issue when I purchased after market rotors from brakenetic.

You can read about it here https://f15.bimmerpost.com/forums/sh....php?t=1572371

I just purchased OEM F85 Rotors albeit at double the cost of the brakenetic ones, which is why I waited so long to get them. That just be arrived today.

I will detail the install here once I receive the hardware from hardparker. These brakes are massive 395mm monsters. I did not realize how big they where going to be!!! Coincidentally that also happens to be the size of the new X3M/4M Brakes.

I just replaced my brakes, so wont be doing this mod anytime soon, but interested in how it goes for you. Any idea what the minimum rim size is needed for clearance? I run 18" with snow tires in the winter, so wonder if those would fit or if I would need to get new rims for winter. I run 20" rims in the spring/summer/fall.

Merlin82 · 06-19-2019, 08:11 AM

Definately looking forward to a write up on how the install and everything goes. Will look awesome.

Pretty sure you need 20" wheels to run these.

TheCoolX3 · 06-19-2019, 09:27 PM

I hunted near and far for some X5M calipers and rotors but no sauce short of new ones from the dealer. I wish I saw them on ebay before I did my brake service!

Interested to hear about how things clear!

Me to..lol I will let you know here! I found these on ebay you just have to keep looking they do come up more often than you think. There are 3 sets for sale right now.

Seller wanted $750 for mine. I messaged him and offered him $600 and he accepted.

TheCoolX3 · 06-19-2019, 10:02 PM

To eaby I go! What style of wheel are you running?

Could you pm me pics of your custom intake please? Thinking about doing the PR coil kit and will have to get crafty with the intake.

Wheels are 20x9F and 20x11R Bravado Tribute. They are intended for Camaros so I had to have the center bore machined out because it was to small, but I got them so cheap I couldn't pass them up.

PM your email and I'll shoot you the pics with a right up on the intake.

Kiemyster · 06-24-2019, 03:13 AM

holy shit this is gonna be sickkkk! what color is your X3 btw? really looking forward to seeing how this comes out. I'm gonna swap out my rotors for drilled stoptechs in a few months and just gonna pull off my calipers and spray them white or blue.

really hyped to see your setup installed!

rcsup1 · 06-24-2019, 12:50 PM

Thanks, I just got the hardware from hardparker and it looks great!

The car is Black Sapphire Metallic. I am painting the brakes BMW Austin Gelb Metallic.

Pic of the car and hardware.

ThomasR · 06-30-2019, 05:14 PM

Very interested. I would like to know if these would fit my 2015 X3 staggered stock wheels.

rcsup1 · 07-01-2019, 01:36 PM

I'll take plenty of pictures once I get them on. I started prepping them for paint last weekend when my die grinder broke. I'll try to have them on this weekend.

You will most likely have to run 20" wheel to clear them.

ThomasR · 08-18-2019, 07:49 PM

So did you get them on? Can you take some measurements?

rcsup1 · 08-19-2019, 10:56 AM

Not yet I have them stripped and ready to paint. I have just had way to many things going on but will hopefully get them on soon.

x3sm · 08-20-2019, 10:19 AM

cant wait

rcsup1 · 08-28-2019, 09:02 AM

Finally sprayed them last weekend. Not my best work but I was in a time crunch. I ordered curved brembo decals but was sent straight ones in error, so I had to reorder. Unfortunately the guy is in Israel so it takes quite a bit of time to get them. I'll try to install them as soon as I get a chance.

rcsup1 · 09-17-2019, 09:12 AM

They are on! Trimmed a little bit of the heat shield and used hardparker's bolt and spacer. I haven't had a chance to really lean on them hard yet but they look amazing!!!

Still waiting for the brembo decals to get here.

TheCoolX3 · 09-17-2019, 10:39 AM

Gosh dang that fills it out nicely! Glad to see these finally installed! Ill have to start assembling a kit for my X3

rcsup1 · 09-17-2019, 07:00 PM

Couple more pics.

najnad · 09-18-2019, 06:55 AM

Whats the stock braking distance? Would love to know how this upgrade effects that.

rcsup1 · 09-18-2019, 09:11 AM

I have no idea what stock braking distance is. Brake upgrades are mainly done to improve brake fade. I can tell you that initial braking feels much improved over the stock brakes and they look amazing

.

My commute to work is short and in the city so I haven't had a chance to really put them to the test yet. I'll report back once I get on the highway and hit them at 100 plus. That will be the real test.

hardparker · 09-20-2019, 07:50 AM

Nice setup, rcsup1. I think you may be the first to be rocking the X5M brakes. What wheels are those? Did you use the stock hoses and wear sensor? Any shots of those pretty spacers? Lol

Published stock braking distance from 60 mph is 125 feet. Stickier tires will make more of a difference than brakes will, most often, at low speeds. My braking tests with Dragy showed identical results with X5 50i front brakes and Firestone Firehawks on shit pavement around town.

I couldn't find braking distances from 100+ mph speeds, but I can tell you the bigger brake setup is far superior there. Instead of smoked brakes and white knuckles, it just hauls down. Fast. Confidence inspiring, rather than frightening.
