How reliable is m235 xdrive in occasional tracking?
Hi.
I plan to buy m235 or m135 xdrive and gonna use it on track rarely (4-5 sessions a month). Here is the question. How reliable is stock (with semi-race brake pads) bimmer on track? I won't use any jb4 or something like it, 326hp is more than enough for me. N54 was very unreliable on track, especially with automatic gearbox. What about n55 and 8AT? What about awd? |

30 track days over 3 years (and 45000 miles) and not a single problem with my 235, on or off the track. after coming from an n54 with tons of problems, i expected the same from n55. however, i was pleasantly surprised.

It was the first time that I had the experience of driving a car so hard that brakes went to the floor - quite a puckering experience. The brakes came right back after a short cool down and I was blown away with how the car handled and put the power down. I asked the instructors what was done to the cars to take the track abuse. The answer I got was "nothing". I think that's a testament to how the M235i is built.

My 240xi zf8 has been phenomenal. Twisty roads of Germany and pushing 370-400awhp and not even a hiccup. The zf8 in these cars is by far the best auto I have ever driven (with that said, I've never driven the PDK Porsche trans which I hear is the same if not better than the zf8).

the auto tranny can handle up to 550 whp without issue.
it can handle heavy abuse. the x-drive can take track abuse very well, if your advanced, run in dsc off mode for more of a rwd feel. the mpss tires are complete shit, so invest in a separate set of wheels and track tires. ebc yellow stuffs are great street and light track pads, but will dust heavily. PFC 08 or Pagids race pads work wonders for a full track pad temed with cross drilled bmw rotors (oem part) and stainless steel lines and motul fluid.

My 2015 m235xi with 45k miles, does awesome at the track. Just came back from Palmer Motorsports in MA. Great challenging tracing with massive elevations. I get some extra traction in spots where front/rear wheel only drive cars just don't. Paddle shifting in Sport+ w/ Manual mode. It's the closest you can get to a full manual without the extra work I just need some longer fingers or longer paddles, i moved my hands down to 9/3 to use them. I'm usually up much higher at 10/2.

I heard that N55 is very "hot" engine (high water and oil temp), much hotter than s54 and other m engines.
What is its average mileage before rebuild? |
