Since the early days M3 has been designed to be track ready this is how it was born. I owned E46 M3 which in my opinion is a perfect balance between street / track capabilities. It is a simple car w/o fancy stuff but can be abused at the track w/o any changes (unless you want to go faster). Specially the brakes which even on my dedicated E46 M3 track was stock and remember E46 is not a light car ... it weights 3400lbs. My biggest disappointment with F82 which I owned are the brakes besides been a really fast car no comparison with E46 platform the brakes are not up to the task. Good news is that a solution exists but will cost you $$$$.
Now I am hearing about the Gxx potential brake issue. Maybe she should wait and see when there is more data but if that confirms could be an indication that BMW definitely moved his focus on M3/M4 to be a super street car with some track capabilities and accept that M2 is the "official" BMW track car.

It is very, very difficult to find street cars that are powerful and have brakes that really take track use.

I'm sure the G8X will be able to take normal track use. Extreme trackers will have to upgrade, this should not be surprising, walk around the top run group of any HPDE and you'll see most cars, independently of brand or price, have aftermarket BBKs.

The E46M may not have cooked its brakes, but is in a different universe speed-wise than a F8X. I tracked mine heavily and had PFC DD rotors front and rear to deal with the track use.

This is a good about other cars. To be honest I never paid attention but will look at it on my next events.

Came across these few interesting videos with G8x vs F8x on track at Bedford Autodrome (UK).

According to the Youtube channel owner Micka LP who was driving the F82:
- F82 Comp was on Cup 2, with chassis setup by Suspension Secrets and stock engine
- grey G80 Comp was on Pirelli with a passenger
- red G80 Comp was driven by Joe Achilles (he has a Youtube Channel) on Cup 2 with a passenger

In the 3rd video, it is the in-car video of the same red G80 Comp driven by Joe Achilles, probably during a different session, posted by another Youtube channel owner nurburgringuk.

What I DIDNT witness is when all things equal (straight) the g80 didn’t leave the f80 by more than maybe a car length, maybe a couple at the long straight. Can’t compare drivers so that’s out, but haters will say the g8x wasn’t past break in so they weren’t fully accelerating and inspector gadget style next time it’ll be different…..

SYT_Shadow , here you go, they put a new M4 Competition on the scale and it tipped over 4012 lbs. And thats 412 lbs heavier than my F80 CS. 412 lbs is a LOT on track.

https://www.bmwblog.com/2021/07/12/v...yno-and-scale/

Hate to say I told you so, but you already know you were indulging in very wishful thinking when it came to the new G80 weights….

That's hefty... and 300+ lbs. more than a light spec base model https://g80.bimmerpost.com/forums/sh....php?t=1826970

With that sort of weight differential, you'd opt for the base for track purposes.

The whole selling point of an M3 is its an everyday car you can take to the track and embarrass more purpose built expensive cars. Its not a fair argument to make to say "you can get a stripped out under-equipped track only G80" to keep the weight down. That's a slippery slope that erodes the very essence of a trackable daily.

Personally, I have zero interest in a manual M3 even if its lighter than the auto/DCT. BMW's 6 speed box has never been that great. Rubbery and never considered among the best manual boxes for good reason.

I hear you, but even a no or low option base G8X is pretty well appointed, no? They don't really make strippers anymore.

I always enjoyed a BMW manual during hard driving and on track. They smooth out and respond well to heat. Difference between shifting on track and feel on a sub-freezing morning was night and day. Unsure how the G8X shifter has been updated, if at all.

BMW M said in one of their videos they made zero changes to 6MT vs. that of F80 because it was already well balanced, except it now comes without a lighted shift knob.
So much for all the excuses of dropping DCT to offer MT.

I can't get over a 4000 lb M3. That's an M5 not M3 and will burn through consumables with even remotely regular track use.

I have a Lotus Emira on order to replace the F80 next summer. 3100 lbs.

I would not trust that weighing, seems like an outlier. As an example, they did not weigh the car on a level ground, weighing the front with the rear on higher ground and then rear with the front higher ground.

Would you venture a guess it’s off by hundreds of pounds, then?

Off by ~100lb sound about right for a loaded M4c with iron brakes.

when my F80 lease expires I plan to replace it with a G80. I am a Manhattan family man so it's one car, road and track.

Not too many other sedans out there with a manual. And most (all) are even heavier than the G80.

sure, I wish it were lighter and smaller but I can still have fun apexing a tank.

I already own an Evora 400 with the Toyota V6 and 6 speed (which I am keeping) so the new car will be the AMG 4 pot with DCT.

Best way to deal with Lotus's amateurish after sales support and parts unavailability? Buy two!

I hear you. If its a street car, weight is almost irrelevant. The G80 I am sure is a very refined (and probably more refined than F80) street car. As a dedicated track car (which my F80 is), weight is exponentially bad and has a very high opportunity cost.
