My first track day in the M2

Doing my first trackday in the M2 at Bedford Autodrome on Saturday. Any suggestions for tire pressures etc? Will be a cold day max temp 6 Celsius (I realise americans use Fahrenheit hence).

I suggest 36-38* hot in F*. Sorry but you'll need to convert. I also strongly suggest upgrades brake pads. The OEMs are NOT up to the task ?- ask me how I know! I use Pagid RS29s for track days now. Easy on easy off. You'll spend more time jacking up the car and removing the wheels than you will swapping out the pads.

Ok, but please note that I did warn you. You may end up with OEM pad deposits on your rotors that you'll swear that they feel like warped rotors, and trust me, you don't want to go there. Here's some more info.

M2 brake issues with OEM pads http://f87.bimmerpost.com/forums/sho....php?t=1419776

Also do a search on M2 OEM brake pads on track. Best wishes!

If the car isn't broken in and you won't be running it hard you will be a hazard and frustration to the other drivers. I would hold off till the next track day when you can drive it properly and prep it as recommended. I would add to the recommendations above that upgrading the brake fluid is a good idea also.

I appreciate the sentiment, I will be running up to 5.5k rpm (plenty fast compared to the other stuff that goes on track days this time of year), ill just get out of the way of the other stuff... im not an advanced track day guy, have done a few in my cayman and also in my mini cooper s before that so not overly experienced. Just going more for exploration to see what needs doing. Are the M performance pads any good? Dont really want much squeal.

From what I've gathered from this forum. The M performance pads are better than stock but not as good as the "typical" pads run (Pagid RS29, PFC08) and more importantly are more expensive than the two I mentioned.

I personally run the PFCs with typ200 and am quite happy with them. I am at an intermediate level fwiw.

Both PFC08 and Pagids squeal like crazy off track. I and others switch them in as needed. It is very easy to change out the pads in this car.

Have fun at the track!

Are the standard brakes really as horrendous as people seem to say on here? Why would they fit them to the M2 if they're so crap? Hopefully will be okay on the day.

They're not crap - fine for the street. I agree that taking it to the track before it's 'broken in' is a bad idea, but it's your car.

They say they are the same from M3/M4 so I can only assume the M2 doesn't cool the brakes as well?

Is it different oil to the one they use regularly? Im not planning on driving the car very hard on the track. Max 5.5k rpm as per run in.

I looked into that earlier and theyre having the same issues. The problem is with the pad, not necessarily the calipers and rotors. The pads themselves are what breaks down, melts, crumbles, smears itself, disintegrates onto the rotor itself which as others have said makes it seem like the rotor has warped

That’s seems kind of weird for BMW to have pads on a M car that will do that. I thought that the M2 was supposed to be made for the track. You guys are recommending things that I used to hear on the 2 series forum for the M235i.

When I did my HPDE in my M235i ,my instructor said that the MPSS on my car were just ok for the track. I’ve always thought that was funny since all the reviewers and people on forums rav about them.

The MPSS are great as a summer sporty tire, for the street.

Curious. M Performance pads? These are an upgrade from the stock that come on the car?

I have yet to do a track day in this car. All my others have had upgraded pads.

Let me ask you this. What if you don't stand on them hard or go deep? How do you think they will hold up?

The OEM brakes are not horrendous and they are perfectly fine for street use. The problem is that the OEM pads break down and smear uneven pad deposits on the rotors when the pads and brakes get too hot.

Yes - definitely get the 1200 mile M service done before the track day. You'll want fresh oil in the engine and the rear diff before the track event.

Funny thing about the 235i and the M2 - I ran stock pads and rotors on my 235i for over 30 track day events. Yes - I used used plenty of pads during my 40 months of ownership. But- I never ever melted those OEM pads on the 235i. And yes, I did track the car on some very high speed, brake heavy tracks.

Now when I first tracked my '17 M2, I got horrible rotor deposits that took way too long to get cleared up. Now on my M2 I ALWAYS swap in track pads every single time for track events. I never ever want to go back to what feels like warped rotors.
