Finally pulled the trigger to refresh the look.
Installing M5 Rep Front, Mtech Rep side, and MTech Rep rear onto MY05 545 w/ Sport.

M5 Rep Front question
I was told that I could get OEM Mtech Brake Duct 51117896587 / 51117896588 to fit to the M5 Rep Front.
Is there anything I need to fit these ducts?
Or Brake ducts on M5 rep w/ fogs won't work unless you do custom work?

Mtech Rep Rear Question.
The Mtech rep new bumper comes w/ 24mm PDC hole but my current sport package bumper has 18mm PDC.
What kind of bracket/rubber grommet do I need to get to make my 18mm PDC work? Part # would be helpful.

Any help from those who have DIYed the install are appreciated especially if anyone knows the part #s needed so I could get them first while they are painted now

For search Nazi: I did my search but couldn't find a definite write up/answer

 

i'd like to know this too. it *appears* that only m tech and rieger include brake ducts, and i'm not sure you can get ducts for the other kits... suggestions anyone?

 

Many people don't bother with installing the ducts because there is no real way to securely fasten them to the grill. After installing the M5 reo front myself, I was determined to hae the ducts installed so I eventually ended up just using a black zip tie (mind you i'm not a big fan of zip tying anything) to go through a slot in the brack duct and it works perfect. You can hardly even notice the zip tie is there.

Here's a pic I just took:

 

thanks socale! appreciate the input! did you use your original ducts then?

 

+1

Did you upgrade from OEM Mtech to M5rep or regular sport package bumper?
Need to know whether the "zip tied" duct is MTech or Sport package duct.

And also anyone else know abt my second question?

 

I used the MTech brake ducts because they matched the profile of the grill area, the only difference is that they didnt bolt into place, hence the zip tie. I have been using this setup for some time now with zero issues and everything works as it should.
