Is it just me or is the rear brake caliper on the new M3 shameful?

mwh2009 · 03-05-2021, 06:00 PM

Seems like they could have done a lot better cosmetically. Even if not dictated by performance needs.

snareman · 03-05-2021, 06:53 PM

Perhaps a larger caliper apparatus for appearance with the same sized actual brake part?

Ilyam5 · 03-05-2021, 06:59 PM

electronic hand brake screwed it over.
All cars have those ugly calipers now. Looks do not bother me but the pad replacement is a pain
One needs a BMW comp to address the brake to replace pads in rear, will be PIA at the track. I'm thinking of just putting g DTC 70 pads in there and leaving them there for the street too.

Genius!! time to start a business selling clip on covers that look like 2 piston calipers

Small rotors, ugly.
Small calipers, don’t care as long as braking power is sufficient.

Big bulky calipers can actually look like ungainly and heavy chunks of metal.

Even Ford managed to incorporate an electronic handbrake along with decent rear calipers on the Shelby Mustang, as do several other manufacturers...

TigahRouge · 03-05-2021, 10:55 PM

The rear caliper looks like an after thought!!

That is also one of my negative impressions- a single piston rear caliper in a performance car....excuses be darned

Is this possible to do on the G8x? Maybe with a custom bracket and use the smaller caliper strictly for the handbrake? Is it possible??

BzsBimmer · 03-14-2021, 12:00 PM

I’m interested in the aftermarket options that will allow larger rear caliper replacement and still provide rear parking e-brake capabilities

kart23 · 04-15-2021, 03:45 PM

Cosmetically? Sure. It doesn't look great, but do you honestly think it needs bigger rear brakes? I'd probably rather have the ~10lbs of unsprung weight savings.

BzsBimmer · 04-15-2021, 04:08 PM

I’d say as long as rear pad swaps could be done in the paddock that match the performances of front pad selection or driving dynamics could be severely mismatched. The track junkies I guess will have a way to swap out both axle sets and not use parking brake assist.

Argument could be said for most all brake setups... focus only on front and no need to add unsprung weight to the rear and leave them alone...

D_SheerDrivingPleasure · 04-18-2021, 08:21 PM

is a brake pad swap on the g8x any different from the f8x...punch tool + hammer to remove spring clip?

Sedan_Clan · 05-03-2021, 08:56 AM

It'll be interesting to see what rear caliper options come out. I will admittedly miss the aesthetic beauty of the F8X brakes.

I can confirm you don’t need a computer or anything to swap pads on the rear as I did them already after two back to back track days

^ good to know. Pre production fear mongering with people saying you need a computer etc. to change rear pads.

Sucks that they don’t last long on the track.

FrozenGT · 05-05-2021, 03:42 PM

Rear bakers are fine! Why on earth are you buying brakes just to look pretty?

Turn off the DSC/MDM. The stability control works largely through the rear brakes, and they will wear much faster than expected.

Of course, the alternative is crashing, so maybe you should just leave it on.
