    Did my first track day in the M4. Only took 2 M4s and 5 years, so that was about time. Some impressions and 4K video below. First track day in 7 years and first time on Snetterton, so I didn't break any records I'm sure. The car is completely stock 2017 CP.

    Noise check - 104db static, the guy was surprised, said it's on the limit, which I think is actually 105.

    Card did great, except steel brakes. They would squeal under trail braking after few hot laps. I didn't push it too hard. It was fine for a 20min stint. I would back off when tyres got to 60C, they look a bit cooked afterwards anyway.

    Fastest lap starts at 48:10
    720S going off track 42:10
    and vanishing on the straight 42:55

    All good fun, but I must admit I went straight to see the McLaren. That thing can shift - shame the driver can't keep it on the road!

    Stupid question but how do you get your lap time and all the other parameters measured? Did you use some kind of device?

    I couldn't believe my eyes when he later took off on the main straight. It's like I was standing still.

    I'm using an action cam, Garmin virb ultra 30, which unlike GoPro can connect to a bluetooth obd adapter (like the one for bimmercode). You can then use their free software to overlay camera and car sensors on the screen. It's a bit expensive, but you can record over 4h of high quality 4K video with it, and it's super easy to use.

    I went straight to see the McLaren outbrake him/herself too. Funny stuff.

    Regarding your best lap, you'll be shocked at how much more speed you could carry through Riches and Coram without much effort.

    You'd also be amazed at how one simple trick could save you £££'s on your heating bills.

    Unless you explain HOW more speed could be carried, I don't really see the point of your post.

    I wouldn't be shocked, I've practised a bit in a racing sim in virtual reality to learn the track, and got down it down to sub 2:04 driving a 1M (M4 not in game, so this was closest). I had the theory covered, but it's not the same when you put your car and limb on the line for the first time :)

    I'm already thinking of coming back in the Spring to put in some more respectable times.

    Have you done one of the BMW M-Performance days? You get to spend a lot of time in an M4 with an instructor and they also record all the telemetry data to work out where you're going wrong, before heading back out to see what improvements you can make. It's expensive, but as you've hinted above you'll definitely go a lot faster when it's not YOUR car :)

    No, I did a BMW experience day, which isn't anywhere as good, and M4 masters at Brands Hatch. But that was few and far between. I might have around 5h total real track time over a decade, but few hundred in various sims. I think with time, I can build up confidence and get quick even in my own car. It's just the initial reaction of everything being a lot more scary and overwhelming. I was also being easy on the car, knowing not to expect much from steel brakes and road tyres.

    Okay
    I thought your lines were excellent, smooth and the car was fast. I've done snetterton about ten times in reality and using the Xbox game Project Cars (also in the 1M), I finally worked out how to be faster through those two corners. The advice (PM'D YouTube video) is only friendly so you don't have to wait as long as me to crack those fast corners.

    I lap snetterton in 2:15 in a stock F80 there are a lot of bends where you can carry a lot more speed. Coram for I'm turning in at around 90mph and maintaining high 70's through the bend. Down the back straight most people stay out wide before turning left into the chicane but you can actually cut the corner braking in a straight line and shave a sec or so off at least. Practice, working up to it slowly and a bit of tuition will do wonders for the lap times

    Guys who are taking part in track days, whats the requirement for insurance? Obviously regular insurance won't cover track use.

    Insure with Manning and they cover UK track days. Track days need to be run by a recognised provider.

    Otherwise there are single use track day insurers. Moris for example.

    You are insuring your asset also you don’t claim of someone else if they hit you.

    Thanks for that.

    I was curious as when I was reading the requirements at Knockhill it didn't state track specific insurance was compulsory. Not what you want when blasting round a track with others!

    It’s not a requirement by the track day organisers but I for sure wouldn’t want to be driving my car around without it, well unless it was a £500 focus...

    Its a track day - why the focus on lap times? If you are having fun and pushing it in the corners you feel comfortable on, then all good, no? On some corners where there is little/no room for error then having a margin for error is a good thing.

    IMHO, chasing lap times on track days is a recipe for mistakes. Especially if you are not doing lots of regular seat time on track. It may just be that I am not sufficiently "driving god" of course.

    I know people do it, but timing laps breaches your insurance and the TDO's insurance. Its just not cool IMHO. Have fun and go racing if you want to get all competitive.

    I agree with you, and it wasn't the focus. I didn't time laps while driving, only extracted the data afterwards. Still, I'm not going to the track to drive slow, I can do that on public roads. It's nice to put a decent lap in and get closer to the limit.
