Cheers for the help, think i best consider this undertray too, or I may attempt to make a joining undertray out of some ally or plastic if i can get hold of some

Jeez, didn't think you needed the undertray, I wasn't going to replace it. Whats the price on the undertray?
I got the centre grill from eBay BRAND NEW for £6, so was a bargain 1 bid sale!
You can save some cash by not buying the two metal brackets for the side ducts, as from all accounts the ducts are very secure without them, and I think they're about £40's worth so a saving can be made there.
I've got mine all ready, just needs spraying but cant find the time to get it done :? (and now the undertray too!)

The M undertray was £70ish from sopers
My old non M tray was ripped from its mounts while doing a country side hoon
I was just lucky it didn't get caught under the front wheels...
In short the 3 inch gap sucks the air in, but once above the tray is has no where to go and so forces the back of the tray down, so breaking out of the mounts (which are £25 each)
If you have converted to an M bumper you would be wise to get the M Undertray aswell
PS you do need the brackets for the air ducts as these too will move and be ripped from the mounts at higher speeds - no point penny pinching on upgrades such as these

The US thread I read states they're not needed, and I agree, as they're held on quite securely in the hatch in the wheel arch liner, and the other end sits behind the bumper opening. I can't possibly see where they could go, and the joint between the bracket and the duct is minimal anyway. Its not like the duct could be pushed through a smaller hole than itself and into the wheel, and its a duct, it allows the air through it so the forces on it are less.
Like I say, this is what others have stated when doing the conversion.
Personal choice, but I guess £40 for the brackets is cheaper than being left with broken air ducts that have damaged their mounts beyond repair
I may just be too cautious, but if they were not essential why didn't BMW save on cost and weight and not fit them to the M...

I agree about the bracket to some extent... the brake ducts are very secure without the brackets.. they dont move at all..... however the only thing holding them against the bumper is in the arch liner.... one big stone, breaking your arch liner and goodbye brake duct... so as ranski says for the sake of £40 its worth it
