Official F8X Road Course Laptimes

[FlyingLow78]

Track: Circuit de Catalunya, Montmelo, Spain.
Time: 2:09.79, measured using raw Go Pro video timing
Car: 2018 M3
Suspension: Nitron R1 coilovers with 450/750 springs and front camber plates.
Brakes: Essex AP Racing 9660 with Hawk DTC-70 front pads, titanium shims, and 3D printed cooling scoops. Ferodo D2500 pads and titanium shims in rear on stock calipers. Porsche front scoops on rear suspension arm and 2" CEET hose to rear rotor.
Wheels/tires: 18" BMW 513M with Yokohama A052 in stock sizes.

Catalunya is a hell of a lot of fun and the grip is immense. Traffic sucked, though, and it was hard to get a clear lap. And yeah, I didn't properly secure my helmet in the video.

I tried using Harry's Lap Timer on my old iPhone 7, but it had issues maintaining a lock on the GPS signal, so it didn't always stop counting when I crossed the line. For my fastest lap I had to revert to the Go Pro frame counts.

I accidentally snapped off one of my front brake scoops, so I ran without it on the left front all day. What I learned:

- It's too hot directly downstream of the radiator to mount a camera. I had one very close to the sway bar in the left wheel arch and it overheated before I had even left the pits.

- The brake rotor is a huge heat sink and it stays hot for a long time, even after a cool-down lap. Ducting is essential to get that heat out!

- The left front brake pads were consumed at a noticeably faster rate than the right front. I recall a video of a team running the M4 GT4 and complaining that it went through brake pads too quickly. I'm going to 3D print another set of ducts, and I will bring a spare set to the track from now on, but I'm in no hurry since the car is now officially in hibernation.

- The calipers never hit 370 degrees or hotter, even on the un-ducted corner. This is a fantastic design!

For the record, when I did this time, BMW's Donnie Isley then jumped into another car and did it in 0:19:894. I was suitably humbled by that vulgar display of pace.

This is a transponder time. RaceChrono app says 1:33.28.

First time on this track. Loved it. T9 is an adrenalin rush.

Here's my 1:33.5 run. My GoPro ran out of juice for my faster 1:33.187 run. Official transponder time was also 1:33.5 so RaceChrono was pretty close. My OBDII adapter didn't connect for some reason so I don't have throttle or rpm data. Critique welcome!

Still far from a perfect. There are some mistakes such as early braking and carrying less speed than the car can handle at couple corners. 1:38 is definitely doable with me driving or even a better time with a more experienced driver.

The video says "Video unavailable". Are you willing to share it again?

My 3rd time in Laguna Seca, with 1:46.63.

Pagid RS29, Castrol SRF, GC -2.3

Putting DSC on all the way, definitely wasn't a a good way to learn how to handle and enjoy the car. The nannies also restricted hard on tracking out and over crest. With increasing familiarity with the track, next time I'd try to get rid of them, by re-learning the limits of both me and the car.

You should be about 1.5 or 2.0 seconds faster with DSC turned off, more if you mean you had DSC on all the way and not in the middle/MDM

First time at streets, tried really hard to destroy an old set of Toyo tires. Was hot, overdrove the tires and they’re still good. Overall a pretty fun but short track.
