1:52.97, sdcamp0000, 2017 M2, DCT in manual mode, stock everything

Limerock Park

1:00.59, dvas, M2, 6MT (Nitto NT01, Bilstein B16 PSS10, PFC08)

Still looking to get a sub-minute time. Getting pretty close but still need to find some tenths. Predictive lap time was a 1:00.18 coming into the last corner but was then held up.

Looked great, if you run Pirelli PZero slicks you'll be a solid 2-3 seconds faster minimum! I noticed that my M4 really handled like a proper track car once I went with slicks.

Nice lap. M2 looks hooked up and sounds properly pissed off with that mic placement. Think you were sub-minute with no traffic. Appeared to be balked a bit even prior to the last corner.

Thanks all for the encouraging words. Was fun developing this micro-build over the last two years and at this point she is really an easy to drive Track day car. Will have to wait until next year to see if I can complete a sub-min time on DOT tires.

The sound comes from a cheap, $20 amazon lavelier microphone taped on the plate over the exhaust. Huge sound improvement over the GoPro mic.

Circuit of the Americas

2:43.74 TulaneAg M4 DCT (MPSS, PowerStop)

Lots of traffic this weekend so I ended up concentrating on putting together clean sectors vs. trying to get a clean full lap. The Optimal Lap on the session where I posted the above time was a 2:41.46 which I thought was pretty good stock except for brake pads.

I also set the above lap time with MDM (american) turned on but I started getting frustrated at its activity level and turned it off mid-session. I started posting some really good sector times right up until I overcooked it on the 8th lap of the session coming out of turn 6 and put it in the wall. Ended up with a dent in the left real quarter panel and I'm going to need a new bumper cover. Overall, not nearly as bad as it could've been...Needless to say, I ran the rest of the weekend with MDM on and only came close to that time once again (2:45.94 was my best time after the accident).

This was my first time tracking my M4 and I felt it was really hard to get a good time out of it. I already have a 981 Boxster S that I've set up for the track and I can toss that thing around brilliantly without a worry in the world. Spending the amount of money on camber plates, track wheels & tires, euro MDM coding, etc it would take to make the M4 dance when I already have a solid track car isn't adding up for me right now so I think her track days are over.

Sorry to hear about the incident. I know a lot of people on here preach running with everything off, but don't feel pressured by the community; run the car with whatever setup makes you feel the most comfortable or use another vehicle to satisfy your track addiction. These F-series BMW's just don't handle like Porsche's or modern GM's.

That sucks man, sorry.

Euro MDM won't cut it either. You'll still be frustrated by intervention. Euro MDM was a bonus for me on the E90 platform because it at least permitted a more liberal tire warm up. Only way to "unlock" an M car on track is (still) everything off. That's not pressure to run DSC off, it's just the way it is. You can have fun and learn under the DSC limit, but if you're looking for lap times, then M division's traction control modes aren't conducive. Porsche, GM have much better developed performance traction control systems

And yeah, if you have a Boxster already set up for the track and enjoy it, then the mod route on the F80 might not appeal. At the same time, it's not a slippery slope to bring an M car into proper street + track spec for intermediate or advanced running -- plates, track wheels + tires (which will fit in the car...), fluid & pads. Once that performance duality is achieved on an M car, it's still pretty sweet. Miss my E90 in street + track spec, and the wide range of opportunities to enjoy the car.

Mind sharing your thoughts on your M4 GTS vs the E90 in track form on the track? Curious how they compare.

Thanks!

Very different cars, somewhat difficult to compare I think. My perception is that BMW changed course post-E9X across the entire model range, so not really a natural comparison E39 to F10, E46 or E9X to F8X, etc. It's way easier to appreciate both generations than declare a winner.

Both cars are hugely enjoyable on track. I don’t know that there’s a clear winner on the enjoyment factor.

GTS definitely requires more from the driver to get the most out of it, so maybe there’s an edge there. The limit is higher, and less accessible. More of a learning curve with the GTS than any other car I’ve tracked. Get the impression I’ll be entertained for years with it, so I like that. And even if I’ve approached the limit with a given setup, chances are that I can make setup adjustments and find more. There’s a lot there to work with and perfect.

With my E90 I was at the limit, or within spitting distance. It was either make it less street-friendly and gain pace, or move on. I didn’t want to compromise the practicality (or long-term ownership) of the E90, so I moved on.

Even with pretty extensive mods, the E90 felt like a street car adapted for track use. Still daily use & highway friendly. Despite some flaws and design oversights (e.g., front camber), the GTS feels much closer to an uncompromising track car.

In terms of objective track pace, not close. GTS is a clear next level of performance. Put them even at corner exit and the GTS has checked out by the next brake zone.

The strength of a well modded E90 has to do with its versatility as I suggested above. It’s also capable of matching the pace of much more dedicated sports cars, and entertaining on an average drive around town. Just a kick ass all-purpose sedan.

GTS is a high-strung track machine. It will do street & highway, but comes to life only when you’re really on it. Can’t be actually understood or appreciated unless it’s really pushed, imo. That’s both an advantage and disadvantage.

Thanks formulammm - cool to hear the experiences of someone who has extensive seat time in both. Figured they were complete different animals - no doubt the F8x platform has a higher ceiling than the E9x. Can only imagine the level the GTS takes it to. Good to hear you are enjoying it!

Ran a 1:01:12 at lime rock today. Mdm on, nt01, gc camber plates, m performance HAS, ferodo dsuno.

Ran that first session and then low to mid 1:02s rest of day with traffic. not sure what it was but the car did not feel as stable in latter sessions.

Was planning on some dsc off practice final session but rain hit.

Awesome time - great job. Would be interested to see the video if you have it.
