Anyone have the brake ducts from Hard Motorsport?

So I have a brake ducting kit I put together myself that runs a 2.5 inch hose to the backing plate from a naca duct in the underbody tray. It works really well. But I chew through hose quickly even with just using it on the track.

I saw this piece of kit from Hard and thought it was a very elegant solution, but have not seen anyone running it.

Anyone have it? Apparently it gets the hoses out of the way of the wheel so you are not grinding on the hose all the time.

I was curious about ducting and using the outlet in the front part of the wheel well. and then running some tubing into an aftermarket backplate. seems as if they only have backplates for M3's so then we can take advantage of these ports. (not the cooler vent)

I don't really understand your question here. m3 is the same. The brake duct is on the same location as non m3.

I was thinking you dont really need the chamber part, but just have an adaptor to the port in my previous photo, and run tubing into a backing plate like this, so that the air goes directly into the hat of the rotor.

Not sure if this backing plate (M3) would fit/work on non-M cars.

The upright is different on non M and M. Read here for ideas. http://www.1addicts.com/forums/showt...php?p=22111627

On bNks334 1-er? Who cares how it looks if it works well. for him doing it. If you care about aesthetics on this mod then you don't really need it.

I ran across this last month and posted in the 1er forums about it...mostly said it was a waste of money for that platform. <shrug> They may be right. Still might do it.

All you need is two of these:


It was a cost benefit thing for me. I spent $50 and have fully functional brake ducts without any issues. Good enough or me , but I can fully understand how most people wouldn't even consider doing what I did.

I have riveted flanges on the back of my backing plates. I was looking at the HARD duct (just the part that attaches to the the frame) to keep from killing the hose so quickly.

Did you get an answer as to whether they will fit a 135?
