The M4 GTS belongs on the track
Featured on BIMMERPOST.com A few observations:
On the street the GTS feels kind of like a muscle car, because you can't safely exercise its capabilities in the corners. On the track it is still a bit like a missile trying to straighten out corners to bury the throttle, but it is definitely capable of holding its own with momentum lines through corners. Related, there was a guy flogging an E39 M5, it was awesome watching him sling that boat through the corners and try to put his power down. My car is now in storage until January due to my home track being closed for winter break. I'll update my post about camber settings once I get out to the track again with a correct alignment + pyrometer + have more than 1 tank of gas. Obligatory track-day photo. This was after the first session, pulled the front splitter out for sessions 2 and 3. https://f80.bimmerpost.com/forums/at...1&d=1574108927 |

Awesome, glad you got it out before winter.
All of your feedback is spot on. Sport+ throttle, MDM, water + gas consumption (about 1:1 on track), need for plates, seat & harness. You got the brakes plenty hot? Only unpredictability I’ve experienced is before they’re in temperature range volcanic. I only got 1 day in with my seat + 6 pt before end of season. Ups the enjoyment factor leaps and bounds. Car is way too fast for a standard seat. Everything about this car that annoys casuals and doesn’t seem to make sense during street use (e.g., sport plus throttle) makes for a killer track experience.

I know a bucket + harness was a huge improvement in control in my STI, most importantly when the car wanted to get away from me. Going to see if I can get some brackets to transplant the seats before my next lapping day. I think the checklist is now 1: correct alignment 2: transplant seats 3: M2C rotors or AP Racing 4: toe links. We'll see how much I can knock out before ~January. |

Also, I wasn't running an OBDII adapter, but the car never got above the 215F range or so per the oil temp gauge. Temps were in the lower 50s, so that helps, but really nice having a factory car that doesn't overheat after a few spirited laps

Temp doesn't budge after 20+ mins in 80-90 degree ambient. Like I've said before, pop the hood post-session and it's cool as a cucumber in there. It's weird.
Tires are the weak point from a thermal standpoint. (Probably need slicks...) Run the CCB through ~1/2 the front pads, then swap. Won't hurt. I have an ongoing exchange with Rebrake.de on CCB refurbishment btw. No red flags so far. Will update other thread with full info once I have. VAC motorsports for maybe easiest route to race seat install https://store.vacmotorsports.com/rac...f8x-p3809.aspx Yes on the improved control. Mostly though I enjoyed not bruising my left knee on the door and death gripping the wheel to stay put.

Believe the VAC side mounts have notably more adjustability than Recaro -- up, down & left, right.

Tires are definitely the limiting factor. I'm on the original set that shipped with this car, once I burn them down I'm either trying out RE71Rs or NT01s. Will be curious to see how tire temps go as I get more comfortable carrying momentum. I was overbraking heavily to keep corners safe, which was probably murder on the fronts. We'll see how the seat mounting goes, I need to inventory what I've got that could work for the F82. I need to swap another engine into my STI(story of this car's life), so the GTS is in storage for the next 6-8 weeks to coincide with the track being closed. |

What I learned is that any race seat install other than factory is likely to involve some compromises, plenty of trial and error. BK stuff? I'm all ears on plug and play solutions for the future. thanks

Not sure how tall you are, but having the seat as low as you are comfortable with is a good thing. Gives you a lower center of gravity and moves you head away from the roof. Seems awkward at first, but lower is better!

This, for sure.
I've been down the road of Recaro sliders and Macht Schnell hardware. What a bunch of shit. I still have that crap in the basement as I haven't had the courage to sell it to a fellow M owner BK is the way to go. They allow you to reuse OEM sliders which are on a different planet than any other sliders as well as maintain the 3 point and 6 point functionality. I have had their goodies on my E92 and E90. When I got the CS I didn't even look elsewhere, I just directly bought their stuff and couldn't be happier. Gomeler I remember your thread asking for advice. Glad to see you went for the GTS, it is insanely cheap for what it is. Make sure to get the camber plates, etc. You may also benefit from a 10.5 et40 square setup in 19" that clears your CCB and allows you to run massive tires like the 295 hoosiers. Or a wide set of RE71s while you get up to speed. The cooling capabilities of the F8X M are truly exceptional |

I installed a weird seat too, so I can't use the Bk stuff. Different bolt patterns. |

That seat belt buckle location is not safe. It’s supposed to be inside of the bolster. Could result in submarining |
