They get so ratty, the black cleans them up so much behind the black wheels. It can be done while they're on the car too if you like. Good stuff.

Super interested, sent a PM.

FCiscoX5M · 06-12-2022, 02:09 PM

Also very interested, PM sent.

I had a custom bracket manufactured and also custom brake pad was manufactured to fit the rear GT4 caliper and also to cover the whole area of the rear rotor... I'm pretty sure Tronik's pad leaves a bit larger rust ring on the rotor... so the brake pad I designed with help of the manufacturer in California (Porterfield Brakes - made out of R4-S compound) is almost twice the size of the OEM and it covers the whole rotor like OEM without any additional rust ring and also looks like the front OEM pad- the portion that is sticking out the caliper..
The pad I designed also has the brake wear sensor slot and it's a low dust ceramic pad made out of their most aggressive sport compound...
swap is a simple and straightforward thing..
breaks work great, maintain the OEM feel since the rear 4 piston ratio to OEM size is about 101%...
I ended up spending over 3 months developing all this and seems like went through a bunch of pad designs and different brackets....
all in all this whole kit including pads without stainless steel lines ran me about $1300 so compared to $1600 plus pads from Tronik I think it was a no brainer...
If someone is interested in this PM me. I can get these for you... I'm definitely all for getting rid of those ugly rear floaters!

Enjoy!

Hey bro I’m interested in this setup for my x5m…
2017 oem color calipers.

Total cost to 33311, Lauderdale Lakes Florida.

As an alternative, Tro-nik Engineering offers these kits for many brands of vehicles. This is where I got my rear Brembo calipers from. However, they didn't come with rear pads, but the pads are easily sourced as they were used on a variety of Porsche from Cayenne, Panamera and 911.

Hi, the kit runs $1150 shipped to you.
Pm me for details.

Blue By You · 08-15-2022, 09:02 AM

IMO Cbozz's kit is way better just for the simple fact that the caliper doesn't arch in the opposite direction of the rotor/wheel. That is a design flaw in my eyes. The Cbozz kit is aesthetically better, hands down. Something I plan to do in the future as a reward to myself.

Seattlesquash · 08-15-2022, 10:22 AM

Me too, already talked to Chris a while back and impressed with all I seen/heard, just sorting some other things in life first but getting close. Can't wait, thanks for great product/service. Cheers

Totally agree, should have been like this from factory. In saying that this upgrade looks just that, like it came from factory! Looks amazing.
