A track tool is the M4 GTS and to a certain extent the M4 CS.

Hopefully the upcoming S55 variant M2 will be positioned as such but this will be reflected in the pricing.

Maybe "track tool" is the wrong term, but it is definitely advertised and reviewed as a capable track day car.

When you look at BMW's own media promo pics, almost every single one shows the M2 on the track. Most reviews will describe how great it drives on the track and even handles better than the M4 at some tracks. Most of these reviews shows 1 lap. But you do see that from time to time, when pushed for say around 3 laps in warm conditions, it starts having cooling issues that leads to loss of some power.

Now BMW advertises one of the car's feature to be "Track-ready cooling system". http://www.bmwusa.com/Standard/Conte...s/default.aspx

A track ready cooling system should do better than heat soak after two 1/4mi runs or overheating from 3-4 hard laps. Now, I do agree that it is the entry level M car and there shouldn't be huge expectations of it putting down killer lap times one after another. Maybe the media over-hyped it a bit and the marketing guys at BMW misrepresented a bit.

M2 lose power overheating in a single lap on some of the demanding tracks, well every car does more or less.

Track ready cooling is more about its engine cooling (oil and coolant), which m2 is indeed very impressive with. As for IAT, the factory IC is an under-engineered part from m235i that is incapable of dealing heat from small turbo running high boost inefficiently. You will just want to use an aftermarket IC that balance cooling and flow well. It’s that simple and effective, without even losing stock power delivery in any way. Then you will be truly track ready, cooling wise.

Next, look at brake (pad, line)

Which aftermarket IC on the current market do you think is the best to achieve that? Obviously you don't want to lose any response and power delivery when driven normally.

Don't go for size if u don't want to lose response. Go for one with a more efficient core than the OEM (which is not easy as the stock one is quite efficient for its size). The problem really is the smallish turbo being pushed too hard even in stock trim. No matter how good ur cooling system if the turbo keeps on overheating there is not much u can do. The IC doesn't cool the turbo. Running less boost would be better so I would refrain from any ECU tuning for more power if u want more consistent power lap after lap
