Big Brake Upgrades via the BMW G series catalog

[DarkZupra]

Install completed, took it out this morning to bed them in. Performance is fine but brake pedal feels like shit. Going to have to bring them to by buddies shop and have him ISTA bleed them. Sigh.

@DarkZupra Not sure if you saw these yet, but adapters to space out the rear calipers for the M rotors:

Yep did see that. Glad he is selling them seperately now. I decided the cost to get a set of those over from Europe wasn't worth it for me, but its a good option to have.

Brakes properly bled and feel great now.

I went over everything and it looks like I spent about $3700 on this project. Some of that is the rear G80 rotors I cant use, so hopefully I can sell those. Some of it is getting the calipers refinished.

I suspect if you spend some time finding good used parts (and buying the right parts the first time), you could do this for between $2500-$3000 all in.

Now someone buy my BBK so I can pay this off

Hell yeah! Thank you for taking one for the team lol. Ill keep this thread in mind when/if I decide to upgrade. Always kinda liked the SignatureWerks ZL1 kit but this is interesting

Could def do it for cheaper than 2500-3000. Just have to be Ebay patient.

Just remember 18" wheels no longer workie.

Its certainly possible. Using my costs, minimum spend would be:

4x Calipers - $1300
Front Caliper Adapters - $350
Front Caliper studs and nuts - $90
Pads - $400
4x Rotors - $700

Thats $2840. Could you get calipers a little cheaper? Sure. Rotors cheaper? Maybe. But Id suspect $2500 is around the minimum, unless youre ok with some REALLY beat up parts. Just my 2c after running through this project.

Yea it does add up quickly. You just need the larger OEM carriers for the rears. No need to purchase whole calipers. That said, I purchased good condition whole rear calipers for cheaper than new OEM carriers alone.

Ohhhh thats right. I need to go through this thread and make a facts sheet lol

Hello guys, I bought g30 brake kit and 370 rear caliper from G11, Now I upgraded my m340i to 374front and 370 rear, but the question is, What are the pads compatibility? The G30 pads from 348 mm and 345mm works on 374 and 370? Or is different, because no vendor know this when they sell this kind of pads. Thanks
