- The BMW track at Thermal (and the configuration we used) is not super high-speed like a normal road course - I doubt I broke 75-90mph at the fastest point
- I was pushing pretty hard and was able to get within 1/2 second of (again, supposedly) fastest time on the configuration used
- I ran in Sport Plus mode
- There was really only two hard braking zone - one after a straight and then another at the end
So, I guess my questions (and point of this thread) are: at what point do the stock/OEM pads start to fade and eat themselves (as everyone claims)? Do you really need to get them super hot by doing 100+mph entry into a braking zone?
I was seriously pushing since it wasn't my car and they wanted us to be hard on the cars. The timed "hot lap" actually ends with a dead stop in a box so you'd come to a complete stop after a ~25 second lap. We did this around 12 times in a row with a little bit of break in the middle (but we weren't exactly letting the brakes cool down). We were sitting in the paddock - at 0mph - waiting for our next run.
Otherwise, as it was my first time actually driving the M2 in anger (and since I really didn't care if anything happened to the car), it was a really fun experience to see how capable the stock car is. It's incredibly well posed and its very easy to rotate and feel weight transfer. We were (unfortunately) on the Contis (as they are a BMW Performance Center sponsor) but I can't really compare to the Michelin PSS since I haven't really driven on them in anger (only canyons) - soon though. I was able to get the Conti's pretty greasy if I was sliding around more than I needed to. The M3/M4s were also fun to drive and power-slide around the dry skid pad. |
From the moment that the M2 dropped back in early 2016 with a press event at Road America in Wisconsin , BMW has not shod an M2 for the press or at any of their performance center events with the STOCK pads if BMW knows the car will be going for anything more than a drive in the country.
For the first time since I am aware of, they supply all M2 that will go on track with M PERFORMANCE pads, an OEM upgrade.
This should give YOU pause about taking your own M2 on the track without upgraded pads.
I just opened my newest issue of BMW CCA
ROUNDEL magazine and there is an article about the M2 in it and the writer recommends not taking the car to the track on stock pads, something i have said since I first drove an M2 on track in early 2016.
This is very simple. If you've been to a track event and are an intermediate level or higher driver , you will wish you had spent $500 on brake pads by the end of a 2 day weekend.
That's pretty much a promise.
Don't listen to me... I have only been driving BMWs on track since 1997. Listen to other M2 owners here.
