Hey guys im thinking about swaping some E46 M3 brakes on but from what i heard, swaping the rear brakes is not such a good idea. Would a brake bias valve to the rear brakes work? And is there any other way of swaping on the brakes without swaping the hubs? Are spacers between the hub and the brakes safe? | | | 04-16-2006, 05:28 PM | #2 | Senior Member Join Date: Jun 2003 Location: Greenville, SC Posts: 9,356 | Quote: Originally Posted by jbxblitz Hey guys im thinking about swaping some E46 M3 brakes on but from what i heard, swaping the rear brakes is not such a good idea.

The E36 325/328 vented front rotor upgrade is fine. If you want to go further, do the E46 330 upgrade. I believe there are people who have done M Coupe rear brakes. You do not want to increase your brakes in the rear. You can work out brake bias by using different pads also. __________________ ...steven BMW CCA #146825 1996 BMW 328ti • 2003 MINI Cooper S • 2016 M235i www.bmwcca.org | | | 04-16-2006, 11:16 PM | #3 | Senior Member Join Date: Aug 2005 Location: Southern Cal Posts: 113 | Sorry.. hehe my reason for the why is... my friend has m3 brakes and is thinking about giving it to me. soo i thought it would be ok since hes only selling them to me for cheap. i dunno would the 318ti brake master cylinder work on m3 calipers? | | | 04-17-2006, 12:29 AM | #4 | Senior Member Join Date: Aug 2004 Location: state college, pa Posts: 3,431 | Ideas don't become good ones simply because it is cheap to do so. In fact, it is usually the opposite that holds true. Too much brake in the back = back end sliding out = loss of control. Leave it to your front brakes, as they provide 75% of the stopping power anyway. Even putting M3 rotors up in the front is a hassle, with new hubs and min 17" wheels. Looks cool, but you'll just be adding weight without any benefit. __________________ I scream, you scream, we all scream for ZOMBIES. | | | 04-17-2006, 12:32 AM | #5 | Senior Member Join Date: Jun 2003 Location: Greenville, SC Posts: 9,356 | Quote: Originally Posted by aceyx Too much brake in the back = back end sliding out = loss of control.

It makes the car unstable. __________________ ...steven BMW CCA #146825 1996 BMW 328ti • 2003 MINI Cooper S • 2016 M235i www.bmwcca.org | | | 03-16-2012, 11:15 PM | #6 | Junior Member Join Date: Mar 2012 Location: charlotte nc Posts: 6 | 1996 318ti ok i got m3 wheels 17, 1997 m3 calipers , m3 disk m3 spindle is that all i need | | | 03-16-2012, 11:41 PM | #7 | Senior Member Join Date: Jun 2003 Location: Greenville, SC Posts: 9,356 | Off the top of my head, rotors and bracket for the caliper. __________________ ...steven BMW CCA #146825 1996 BMW 328ti • 2003 MINI Cooper S • 2016 M235i www.bmwcca.org | | | 03-17-2012, 01:51 AM | #8 | Junior Member Join Date: Mar 2012 Location: charlotte nc Posts: 6 | m3 brakes bracket? calipers dont bolt on to spindle ? i dont have no brackets | | | 03-17-2012, 02:00 AM | #9 | Senior Member Join Date: Oct 2008 Location: Los Angeles, CA Posts: 1,464 | Bracket looks like this: It bolts to the spindle (lower bolt holes) and the caliper bolts to the bracket (upper bolt holes) Add me to the list of people advising against doing this swap... | | | 03-17-2012, 02:47 AM | #10 | NOBODY F's with the Jesus Join Date: Oct 2006 Location: Ventura California Posts: 7,824 | I've read the "Size Matters" thread and all, but I'm still going to say that despite what others may believe, there's no way that the stock 318ti non-vented rotors and tiny calipers are going to stop better than the massive piston, larger diameter/vented e36 M3 brakes. Yeah, there's a brake bias issue. But on 3/98 and later ti's, they switched to vented rotors up front. What did that do for brake bias? As long as your fronts bite harder than your rears, you're gonna be fine. I mean, if your rears locked up before the fronts, that would be dangerous. Bluebimma has a solution "in the works" regarding M3 rear brakes and brake bias. http://i685.photobucket.com/albums/v...s/34df01b1.jpg Last edited by cooljess76; 03-17-2012 at 02:51 AM. | | | 03-17-2012, 10:18 PM | #11 | Junior Member Join Date: Mar 2012 Location: charlotte nc Posts: 6 | m3 brakes | | | 03-17-2012, 10:41 PM | #12 | Junior Member Join Date: Mar 2012 Location: charlotte nc Posts: 6 | m3 brakes how u got the back ones on i c he got them on in the pic | | | 03-17-2012, 10:52 PM | #13 | Junior Member Join Date: Mar 2012 Location: charlotte nc Posts: 6 | 46mm socket no one carry them | | | | Currently Active Users Viewing This Thread: 1 (0 members and 1 guests) | | Posting Rules | You may not post new threads You may not post replies You may not post attachments You may not edit your posts HTML code is Off | | | |
