z4m bumper

If I recall you have to do a bit of cutting on the M undertray edges to fit the non M, nothing too drastic

Sorry but I don't understand. If I have M bumper, M central undertray and side undertrays from the M aswell, what possibly cannot fit there that cutting is necessary?

[maxman]

If you fit the m undertray only,you have to do a bit of cutting on the std side trays to make the m undertray fit.That is the way I fitted mine and I have had no problems.Hope this clears it up.

[Panta Rhei]

Yes, it does. Thanks.

A couple of questions if anyone can help, if i have a M undertray without the M side undertrays will i still need to cut the M undertray, if so if i have the M undertray and the M side undertrays will that fit without cutting.

And the last question is do you really need the M side undertrays will it fit fine without them

It says a few posts above. If you have M undertray (you don't cut this) and you can use original side trays but they will need cutting.

Not sure if you use M sides. I assume that no cutting would be necessary.

As above, M bumper and M undertray are left alone, if using M lower corners they are also left alone. If you have standard lower corners like most who do the conversion do (me included) when you offer up the bumper you will see a small area where the fangs foul the lower corners, and you just have to cut a small section out of the plastic and then it all sits fine. It’s honestly not hard and you will see exactly what we mean once it is offered up

Certainly nothing to worry yourself about.

Shameless //M front end conversion snap

Not the greatest of photos, but you can see where I have trimmed the plastic in the red circles.

Hope this helps

OP don't bother, go for the aero setup, i think its less common and much cooler!

I bridged the gap by screwing in a bit of plastic

Cost about £5. - the undertray is so expensive

Guys, does Z4 M bumper require the piece below? I thought you attach undertray to bumper itself and here in my car there is additional connector between bumper and undertray.
