Have you upgraded the Brakes on your g29 Zed 4? Pads or Rotors by chance?

I’m sure the Zupra community has, and that is probably my next stop…

Any information is highly appreciated. Thank you in advance.

No, for street driving I haven't had any problems. I get the brake fluid changed every other year.
Excessive brake dust is my complaint with our brakes.

What do you hope to improve?

I own an M car currently and I am not easy on brakes and I understand these brakes are prone to fade when used repeatedly while sport driving

I’d expect to upgrade the rotors and pads as well as change to better fluid

Changing fluid annually is a great idea so you’re very smart to be doing so as often as you do…

Yes, I’m using an AP Racing BB kit (6 pot) and it’s way better then the standard M brake (4 pot Brembo).
For normal driving the standard brake is more than enough,but I had problems at higher speeds (200km/h +).

Do they fit under the 19” OEM Wheels by chance !?

According to the vendor's description, they do.

Thanks I was looking at my phone I couldn’t see that. Thanks for putting it out.

My brakes are getting worked on in the shop today. If you do aftermarket brakes, I would assume the warranty from BMW is no longer applicable?

Over 70 mph (*wink wink) and in the wet and when overheated my brakes were ineffective, but I think something is wrong that will be corrected. I'll let you know what they find.

Warranty on the brakes sure… however they cannot void the warranty on anything else unless it’s directly connected to what was altered or changed

Keep me updated on the outcome please

Yes, it fits the 19” wheels. The caliper is designed to work with up to 390mm rotors but it would fit only with 20”.
Regarding the brake discs is important to know, that AP racing has NO kit for the Z4. It means, that the shop (Whifbitz, Essex…) offers a mounting bell, which fits only one disc type. Whifbitz works with 390mm brake discs (made for Audi RS6) and it turned down to 382mm for common use. I guess you could go for the 390mm if you has 20”, but you should ask them.

Another option would be the Stoptech, with an 380mm BB Kit - 2800 EUR special offer.

I appreciate it

What are you using for rear pads?

Did you change lines and what fluid are you running ?

At the rear I’m using the EBC yellow stuff pads with Paragon discs.

It’s also a 2piece disc, but not full floating like the AP.

The brake lines comes with the BB kit.
Fluid is the BMW OEM. However for hard track use is an other fluid recommended with higher boiling point.
