It’s been six months since I got my Man Green 2021 BMW M3 G80 generation. And of course, I had to get a six-speed manual paired with the bold new M3. Fast forward to today and the G80 M3 has hit 10,000 miles on the odometer. Or should I say “smiles”? First, just a brief history about myself. I am 32 years old and have been an avid BMW fan for the past 20 years.
I remember my first Roundel magazine when I was a kid which now had the legendary E46 m 3 on the cover. This is still my favorite M3 so far. Ironically, this year’s June edition (the same month I picked up the car) had the IOMG/KO G80 M3 on the cover, just like mine. Was it supposed to be right? This is my first BMW M car, but I’ve driven several previous M models. I am also around them a lot since I run the Philly Bimmer Club and host many meetups during the motoring seasons.
A large number of mods
The point of this review is to focus primarily on my modifications and the daily driving experience of this beast for the past six months. A lot of modifications have been made to the car, so fair warning ahead. Some of the current modifications are as follows:
- Mobile flash ceramic coating
- PPF mobile flash and light color
- H&R . Sports Springs
- SSR Catless Downpipe
- Motorsports Burger JB4
- Motorsports burger sockets
- R44 Performance Carbon splitter
- R44 Performance Carbon Ducting
- R44 Performance Carbon ducktail wing
- R44 Performance carbon side skirts
- BlackVue dashboard camera
My G80 M3 now makes 660 watt-hours and 652 lb-ft tq on E35 fuel using a JB4 OTS Map 5. Recent drag test showed 0-60 mph in 3.88 seconds on stock tires. The distance came between 60 and 130 miles in 7.12 seconds. MPG is 18.1 on average (60-40 highway/city).
As everyone knows, this new M3/M4 was screaming for a cut with how much wheel gap it had stock. The H&R Sport Springs was technically my first modification and I did it right after service the following month. At first, I wasn’t happy with this drop. The front still had a pretty big gap but after a few thousand miles it happily settled down. I wanted a conservative drop because I knew I was going to have an R44 lip soon and didn’t want to break it like I did three times in the last 340i. Philly/Jersey roads are horrible. The ride and handling are very good and the comfort is like stock. I will probably switch to something a little lower once I install new wheels because setup is everything.
Another thing the G80 M3 lacks is the exhaust sound volume. It actually had a decent tone stock but was very quiet. After thinking a bit between the twin tubes (PSI) and single tubes (Valvetronic), I went with the latter. The single center tube gives a deeper tone to the inline six. I completely changed the car’s sound. All of the aftermarket dual setups have a lot of rasp in my opinion. Make the exhaust 30 percent higher with additional rifles. I also made a dyno and added the middle tube 10-15 whp. So normal.
tons of new energy
After that, I went even more aggressively. Now, that doesn’t mean the car isn’t a solid stock. It is none other than the Burger Motorsports JB4 that has put me on a level playing field with the M3/M4 competition since the only difference between the Comp and Manual is the level of boost in the turbines. This was a game changer. power and torque s 58 Delivering on ethanol is absolutely amazing. The car does not sweat and challenges you to push it hard. I know a lot of people are now going to start setting flash but the process is a lot of trouble at the moment. JB4 has been great and I will be sticking with it for a while longer. As always, using a tuning solution on your vehicle may void your warranty, so don’t follow my steps if you’re uncomfortable tuning your vehicle.
More audio upgrades
SSR Catless Downpipe – This was my first time going without cats. I have only used downpipes. Oh boy, did this make a difference not only in sound but in performance. The car looks like a freight train. It is intoxicating. Throttle response, exhaust screeching improved, and I got a 40+ whp/tq on top of the JB4 OTS map. Factory valve control does a tremendous job of keeping things calm when you want it to.
In active mode, the car is just like the stock under 5000 rpm. I use this when commuting to work. Sports + is what I use the other half of the time and this is full of obnoxiously loud noises with the loudest noises. Sports is kind of in between both modes but I rarely use them. All or nothing to me. However, this down tube is not a flexible tube and it took some custom welding to fit the middle tube perfectly. There are now some flexible tubing options that are easy to install.
Since I put the exhaust in, I had to give the engine bay some love until the “whoosh” sounds came in. I love Motorsports burger sockets. The butt dyno immediately felt more throttle response and increased torque. The dinos made to these intakes also prove to increase the power/tq. The spooling and “blowing” sound is great and will never get old.
To improve the styling of the BMW M3 G80, I chose the R44 Performance Carbon package. Carbon ducts, splitter, side skirts and wing enhance and complete the vehicle’s appearance. Especially the front end that was calling for the break. I added my personal touch with matching paint tape on the divider and side skirts. The quality of the pre-carbon is top notch and same as OEM. People who didn’t like the front end have come to love it now! You can never have too much carbon and there will be more to come.
The BMW M3 2021 is amazing. I love driving it more and more every day. Maybe I should back off a bit because I put in 10,000 in the first six months. It’s just good and fun. Modifications have transformed her from an awesome car into an absolutely brutal machine. It’s a quiet, comfortable four-door family car, grocery keeper, and commuter with proper gas miles. But with the push of a button and the gas pedal, it turns into a brutal, loud racing car. It truly is a jack of all trades. The clutch didn’t slip once even when pushing a lot of power/tq through the 8000 miles or so I had a JB4.
Some people think the Manual was made as an afterthought, but no, it was enhanced to handle more than any M car before it. It’s a special feeling to beat the automatic cars on the street and be tracked by switching the stick! The handling is great and is planted through nooks and crannies. The brakes are great, despite the brake dust nightmare. The car gives you complete confidence that it can handle whatever you throw at it (responsibly). Some of the other minor annoyances are that the Harmon Kardon’s are a cutback compared to the last generation, but I listen mainly to exhaust noises anyway.
In the $80,000 – $100,000 range, no other car can give you what the G80 M3 has to offer especially after some upgrades. It looks great and gets compliments left and right. It looks amazing and breaks necks. Driving like a dream. Built like a tank. It’s the ultimate driving machine and BMW just bumped it out of the park!
