Is there a good reason to pay so much extra for an M3 for track use? It seems like you all are doing just fine with the M340i. I've been to the track exactly once in my life with my old 335i and I would like to start going more. But obviously I'm a newbie and I'm not going to track more than once or twice a year at a maximum. Btw, my '07 335i did overheat and go into limp mode. That wasn't the greatest. For me it was a blast and way more than I could handle. So I'm kind of thinking the M340i would be a better street car and plenty of track/autocross car for me.

Regarding the M340i, it will certainly do fine on the track if you go once and awhile. But if you go twice a month like me, a M car offers a package that you can't get in an M Performance car. Now, if you want to strip down your M340i and build a track car then by all means, it will perform better than a stock M3/4, but overall you are starting with a better package with an M car.

Thanks for the reply. I'm definitely not going to go to the track more than a couple of times per year. I'm thinking with the extra cooling package on the M340i I should be OK to go have fun and not break down.
Is there any benefit to the M3/4 on the street? The only advantage I can come up with is if I go with the manual transmission on the G80. Other than that, the M340i will be plenty fast to send me to jail. I should add that I test drove the M2C and I can see an advantage on the street. It's really nimble and stupid fun. It's just tough with a family. I'm not sure an M3 would be fun in the same way. Last edited by bmwdrive; 11-23-2020 at 07:18 PM.. |

I have two track experiences with the car. First was at the performance center when I took delivery. What an incredible experience that was. Second is I took my car on track for one session at the ///MPact event at Pocono (I'm an instructor with NASA, the M340i is my daily not my track car, and I spent most of the time in student's cars). The all-season run flats were a bit of a disaster not only in corners but the brakes could easily overpower them. However, pulling onto the straight I could 100% keep up with a new Camaro SS. Give this thing some sticky (and wider) tires and it would be a hoot on track.

Counterspace Garage sells brake pads for the new Supra. I'm pretty sure the calipers and pad shapes are the same as our cars, might give them a call.

I'm taking mine next week for the first time. I'm excited to see what it can do over my F30 340i.
I'm expecting it to handle much better with the LSD, and just better overall dynamics the G20 has. I tracked my old F30 more than a half dozen times with no limp mode or heat soak stock. I did also have the Track Handling Package.

I was tracking the car in auto because Pitt Race is tricky, and I was trying to improve my lines. I did not want to think about what gear I needed to be in. The brakes held up amazingly, and bit harder than my F30. I did have to get a fluid flush the next day, as post track the brakes felt spongy. I probably boiled some fluid as this fixed the issue. Not sure if I will track her again this year. Maybe 1 more time? I tracked my F30 2-3 times a year with no wear, but I fear I push the car too hard sometimes at the track as it is my daily also. Fun stuff: In the advanced class a guy had a stock car, and it blew it up on the first lap. Also watched a 2000 Honda Civic Si Hatchback blow up in front of me and spew oil all over my windsheild.

I’ll be taking mine this Sunday, and if all goes well an additional track day the following month. Just had the fluid swapped out for Motul 660, kept the stock pads on. I’ve also got a set of the Michelin PS4S on so should have enough grip to be fun.
Weather’s not looking great at the moment though, 50-60s and rain forecast but I’m in the Midwest, so you really can’t judge it until day of. If anything, I’ve never done a track day in the rain so it’ll be good slide/traction practice at the limits if it does. |

So track day went well. With stock pads/rotors and Motul 660 swapped in for the track day, it held together all day, no issues. Ran laps off and on, 10-15min at a time from 8AM to 4PM all yesterday. It was a cooler day (started in 40s, got up to 55-60 - wet until midday), so managed to not have to deal with any heatsoak. Grip was a challenge but improved later in the day.
Topped it out at 131mph (speed limited unfortunately), but it ended up being OK because it was at my absolute braking point with the stock pads I had on. The stock pads just don't have enough bite to truly be "competitive", but as is for track days they are more than adequate. Car needs wider tires - I'm on stock width (8") front/rear with xDrive and 225 tires. Really needs 245 - not sure if going even wider with a staggered setup will make much of a difference - likely. The front with 225 had plenty of grip, never pushed - but the REAR just couldn't hold on. Maybe with a warmer day it'll have the grip. Power was consistent, smooth - fastest lap times I've been able to set - car charges on every straight and hard. I'm happy overall. |

Yes. Too heavy for the track. Powerful engine, excellent gearbox but too much kilos and not adequate brakes for track use.

Curious to know from those tracking if they're ZTK with larger brakes + cooling or not too.

My car has the bigger brakes and cooling package and I had no issues at all with 25 minute sessions all day but Jefferson at Summit Point is a small technical track, 1.9 miles and 14 turns, so not a high speed track where brakes may be challenged...only hit 115-120 on main straight where I would usually get to 140 mph on back straight at Watkins Glen...

Took my loaded G20 330i x drive with perf tires to Road America and went up against my friends G20 M340 x drive perf tires. I blew him away on all levels of track performance and lap times On the straights i beat him as well. He is a semi pro driver and i am as well. BMW sure covers up the Torque and HP on certain models. Glad i went with the loaded 330i. Sport mode in adaptive mode a must have!! Now were headed to Portimao!
