    Hi

    Im a very long way off but a M2 comp manual will probably be my next car.
    I like to do track days and was debating whether or not the BMW big brake option was worth the $.

    I was thinking the stock brakes might be better with some good pads, fluid and braided lines. This is due to the fact that you could then use a set of lightweight 18" wheels and some nice rubber which will keep weight down and cheaper tyre options

    The upgraded brakes are quite heavy and you need to use 19" wheels minimum which adds rotational and unsprung weight.

    Thoughts from fellow track junkies please.

    The M4 GT4 and M235i Racing run 18" wheels, so there is a set of parts that will fit. I think the M235i Racing uses AP on the front, with stock callipers and the Sport Brake Pads at the back.

    Hi

    Thanks for the info.

    Im looking for thoughts between stock brakes and BMW optional brake upgrade which includes a 6 piston front caliper and 4 piston rear.

    The front barely clears the 19" wheel, so avoid gravel traps...

    Assuming you are refering to the 6 piston.
    On further research I think stock brakes might be the way to go with 18" wheels, pads, fluid and braided lines.

    Thanks

    Braided lines on an M2 worth it?

    You could use the stock ones as the M2 is a relatively new car but if you are doing a lot of track days then braided lines might help slightly with pedal feel when your brakes get hot. No point replacing them on a road car.

    I think the 400mm option is great if you are running 20's, but any wheel less than 20" will get scored to death. Plus costs for pads are crazy, and probably discs.

    Get some weight out of it (seats) and use RS29'S OR RSL1'S etc

    Pfc08 pads last a very long time as do their discs.
    Definitely getting weight out is a win but the best weight reduction are wheels.
    I prefer 18" wheel and tyre options as they are lighter and cheaper and give you quicker acceleration and better braking compared to a 19" or 20"
