That's damn funny.

For F8X guys who are planning on making the switch, interested to hear why.

Lap times and track capability tbd. But based upon what we've seen so far, it looks like much the same recipe as the F8X, with some amount of concerning added weight.

And I'm sorry, but I can't believe M is about to release another M3 with the same low level of track-readiness, that requires (apparently) the same suite of modifications for any semi-regular track use. Again. It just sounds exhausting.

Why can't they equip the M3/M4 with at least stock 1LE levels of track-readiness? Or, offer a 1LE type of package?

Happy to be proven wrong.

Exactly.

At least they put 6 piston brakes up front this time.

I'm a first time M owner with the F82 and while I love its street manners, it's a bit disappointing as a car that sees a dozen events or so a year at the track. I understand the balance between the two but it feels like the //M stands for marketing. The lack of development and the information out there (even though this subforum is great) probably has to do with the audience and the price of the car.

Hopefully, this changes as the car drops in market price.

As for the G8X, it would seem the audience is getting even further from the HPDE guys, maybe more drag strip.

And pea shooters in the back.

Know the fronts handle the bulk of the braking, there's a functional argument for the single piston floating caliper, but I gave them a good look and that pad surface area isn't much. For the love of god would they just decisively end the braking issues already

Only mods that would affect hpde for me so far are front camber plates, some track wheels and tires. New brake calipers / rotors coming for more durability.

Guess I am in the minority here, but other than brake pads and camber plates to save the tires, the F series came pretty track capable. Of course pushing the pace requires more mods, brake pads will only get you so far.

In a lot of ways I agree... it's still one of the best chassis out there.

Aside from the braking system being atrocious, the suspension is awful too.

Any tires with more grip than factory will be bottle necked by both.

For casual tracking I'm sure it will be great mainly because of the carbon seats, the base G series chassis is also excellent. But if you are seriously using it primarily as a track car, I don't see how $80k in a basically stock G8x can compete with a nice f8x with $30k of mods. Be interesting to see what the lap times are between stock cars on equal tires, I don't think the delta will be anywhere near what it was between the e9x and f8x.

I do agree with your approach on corner weighting and F80 weight. Here's mine:

Good data point. I trust actual weighing more than spec weights. Your M3cs weight is very consistent with SYT_Shadow's one.

My M4cs weighed ~100lb lighter also on corner balance scales with practically full fuel. A good difference. I would reconcile the difference as follows:
  • 44lb F82 vs F80 chassis
  • 16lb MPE
  • 11lb sun shades (5 of them)
  • 15lb lightweight door cards (guessing)
  • 15lb lower end sound system with less speakers (guessing)

Good to know, all those make sense. Which is why I think SYT is more hopeful than true in his G80 assumptions. Options add significant weight to a car so a stripped G80 versus an optioned F80 is not apples to apples. F80 itself is a heavy track car, I can't imagine a 4000lb G80 to be much fun to toss around. As a street cruiser, sure, you can hide the weight, but on track, weight is weight and weight eats consumables and dulls the senses.

Incidentally, my car came equipped with CCBs and when I swapped out to girodiscs, I added a good 50lbs. My specific CS should be right around 3600 wet out of the factory. It is fully loaded so I assume its the heaviest flavor of an F80 CS.

You guys have some light cars. My 18 ZCP 6spd, CCB, BBS FI-Rs and 1/2 tank of fuel came in at 3747.

Of course it has every option other then the rear sunshade.

Edit: that includes the 175 weight for the driver.

If that 3,747lb includes a 175lb driver, than you are not that heavy at 3,572lb... Which seems in the right ballpark for a well optioned 6MT CP M3.

That are hopefully swappable without caliper removal? How about the rear?

Nope. It seems like calipers need to be removed for a pad swap on the G8X. And you need a laptop to swap the rears

The G80 will be undoubtedly be quicker around the track, because that is a benchmark BMW set for the evolution of the M series.

Also, it will surprise people in some ways I think. Every new series always has. People always look at the power figures and weight. However, a lot of the evolution is often in chassis design, suspension, geometry, electronics (hardware and software) etc.

Will it be more fun? Probably not. IMHO, probably just getting too big and heavy, more like an M5

I'll get one, and take it to the track for some fun. Can't see it ever being my main track weapon. Mind you, that was the story with the F82 as well

Well, the view around here is BMW has to make light, powerful cars and they have to be really really cheap. Really cheap.

If they make a CS that is more powerful and lighter than the G8X it will inevitable cost more, and for many in this forum that is unacceptable.

Whenever the CS is announced and before anyone has driven one, you will find pages of comments of people saying they would never buy a BMW for 'x' price. Then some of those same geniuses would talk about buying other cars that are 2x the cost of the M3, but it all makes perfect sense in their heads.

People move on to cars with a base price of 2 or 3 times the M3, yet are amazed those cars are better at some things and will spend years sticking around the M forum despite not owning any M cars, filling their posts with criticism and hatred for the M3.
Fortunately, you can distinguish the ones that were fast drivers from the posers who buy cars for their brands, as people who were fast and moved onto a different platform like @NYG continue to appreciate the M platform regardless of what they're driving now.

BMW could make a car that cures world hunger and you'd still have people saying for that price they'd prefer a 4 banger engine in a 2 seater.
