Sorry dude just saw this, I used the 1m engine cooler for the DCT all I did is flushed it out as it does fit.

The 135 engine cooler is exactly the same.

The engine cooler I reused from the m3 by modifying the brackets no issues, 1m front bar works perfectly with the engine cooler.

No worries. This is the same thing I've seen others who have done the 1M body do, interesting that the 135 is that much different. The 135 oil cooler doesn't work with the DCT cooler lines, the connection point is too tall, and there's no way the M3 engine oil cooler fits in the 135. I ordered a CSF DCT cooler so that shouldn't be an issue other than the outer two duct screws not fitting. I'm making a custom oil cooler bracket for an aftermarket oil cooler... pain in the ass.

Strange, just check the oil coolers on realoem and see if the part numbers are different between the 1m and 135i.

The csf m3 dct cooler wont fit our cars as the ducting is different but possibly if you modify the m3 ducting and guard liner it may work, haven't looked into
it as it wasn't needed in my case.

There is so many variations between the models that what works on one doesn't work on the other and that includes the engine loom, that is why when you order parts you have to supply a vin and when people ask if a kit can be made the answer is not a chance.

The cores and everything are actually the same size between the 1 series oil cooler and the M3 DCT cooler, the only difference is the height of where the lines connect, and the two ears where the duct connects on the outside. The duct connection I'll just zip tie or something, not worried about it since you can't see it, the DCT lines are hard at the end and don't fit into the connection point of the 1 series cooler well. I can unclip the lines along the fame rail and they will connect but then they're flopping around and it looks half-assed.

May be totally different for the 1M, who knows.

You can see in Brintech's videos they just cut the outside mounting ears off the M3 cooler and mounted it up:

holllllyyyyyy shit! Awesome!


Yes, those crash bars fit. I have been trying to snipe some one Ebay for the weight savings. https://www.e90post.com/forums/showthread.php?t=1282179

So with quite a bit of trimming to the outside portions of the crash bar it does fit. I wouldn't do it on a road going 1 series since the tow hook cover won't fit any more but for a track car it seems like a great way to save 9 lbs at the best area on the entire car to save it.
