Hello,
Has anyone have any good input about adding M calipers on front 70 914. Different rotors, thicker pads ? Any pros or cons. any help would appreciated. |

Positive- They have more stopping power (if you need/want it) than stock calipers.
Negative - They only work on 3” 911/914-6 struts and hubs. |

The rear 911 M calipers have a 3in bolt pattern like the 914 4, is there a rotor to use or thicker pad ? M calipers, except for the solid rotor model on 912’s use a vented rotor. To use M calipers on the rear, you need a 911 ebrake ( I believe early works best) and tangerine racing adaptors. And some grinding and welding. |

Sorry, the point isn’t very clear.
Using rear M on a stock 914 front? Probably not due to rotor & hub spacing. The caliper also uses vented rotors. If it’s some other configuration, probably not that either. 914 & 911 brake parts don’t usually play nice together. |

They have a guide rod on the inside. Will say that Sierra Madre sorted it out, after a few failed attempts earlier. From doing a 911 at the same time it looks like the rears are the same. |

that's what I do! Group: Members Posts: 20,065 Joined: 27-December 02 From: Port Hope, Ontario Member No.: 26 Region Association: Canada |
I have vented Alfa Brembos on the fronts with V-calipers, 914/4 calipers with spacers and turned down 911 vented rotors, on the rear.
The wife's 914 has M calipers on the fronts and welded /redrilled hubs with stock brakes on the rear. The project 914 will be getting Alfa Brembos on the fronts as well. |

This is a difficult post to follow...(maybe the coffee hasn't kicked in yet...)
The OP's initial question was installing M calipers on the front which was quickly answered. In post #3, OP comes back and asks (I think???) if 911 M rears will work on the front of stock struts (???). It may be helpful if the OP helps refine his question on what the end goal is...ie, street or track/autocross, eliminate brake fade, improved braking due to high HP engine swap, etc. I think it would also be helpful to readers if the OP specifies if this is only an enquiry for front brake upgrade options. Is the OP limited to a budget upgrade and not intersted in upgrading the struts? Just my $0.02... |
