G8X M3/M4 (2021-Present) 

The G8X chassis of the BMW M3 and M4 caused quite the controversy with its unveiling in late 2020. While the interior, performance, suspension, and just about everything about the generation received a massive improvement, the front grille became a massive talking point for enthusiasts everywhere. 

One of the main changes to the G8X’s drivetrain was the introduction of X-Drive, BMWs 4 wheel drive platform, to the M3 and M4. With all prior generations of M3 being strictly RWD, this was definitely viewed as controversial as well. Luckily RWD is still an option for the M3 and M4, with X-Drive models being able to switch into RWD on the fly. 

The G8X also introduced the new S58 motor. Just like the S55 it replaced, it is a 3.0L inline six with two turbochargers. With a considerable power bump over the S55, the S58 also proved to be much more responsive to modifications. 

Popular modifications for the S58 are similar to that of the S55, a high flow exhaust, intake, tune, and ethanol tuning can yield over 600whp on the stock turbos. Pair this with some carbon fiber upgrades and you can build the G8X to your exact liking.

F80 M3/M4 (2015-2020)

The long-lasting BMW E-Chassis finally has come to an end; and to replace it, the F-Chassis is born. The F80 M3 came with a slew of changes from the E9X, including the introduction of the M4; BMW’s new moniker for the 2-door M3 equivalent. 

Powered by a 3.0L Twin Turbo Inline-6, BMW went back to its roots of an inline 6 engine in the M3, yet modernized it with the introduction of forced inductions. This solved the low-end torque issues of the E9X, and introduced a whole new world of aftermarket possibilities.

Rated at 425hp and 406lb/ft of torque, the S55 powered F8X is no slouch in stock form. Despite most manufacturers straying away from manual transmissions, the F8X comes standard with a 6 speed manual transmission, with its 7-speed DCT counterpart being optional. 

With the addition of an aftermarket set of downpipes, intakes, and intercooler and heat exchanger, power levels of 500whp+ are easily achievable. Add E85 and methanol injection into the mix and you can reach 600whp on the stock turbos. If that is not enough for you, upgraded turbos are an option as well, allowing for 700whp+. 

As with most BMW M-Motors, the S55 has its achilles heel as well, the dreaded crank hub issue. Similar to the rod bearing in the S65, this issue is constantly debated upon in the forums and groups. The general consensus is that the issue is more common in DCT cars that have been modified, yet some instances of the crank hub (spinning) have been reported in bone-stock cars. We believe that if you are looking for piece of mind and want to be able to drive your F8X without worry, then you should consider upgrading your crank hub.

The BMW M3

The BMW M3 is the high-performance version of the ever-so-popular BMW 3-Series. Since 1986, BMW’s M division has taken the normal 3-series and outfitted it with a new engine, suspension, interior, drivetrain, and much much more to create the ultimate sports car.

BMW E90/E92/E93 M3 (2008-2013)

With its introduction in the 2008 model year, the E9X M3 was a revolutionary change over the previous generation. This M3 is the first and only M3 to be powered by a V8. The E9X generation was offered as a coupe, sedan, and convertible. 

The most iconic part of the E9X M3 is the drivetrain with its S65 4.0L V8 making 414hp and 295 ft-lb of torque. Offered with a 6-speed manual or 7-speed Dual-Clutch automatic transmission, there is no correct answer on which to choose. Singing all the way up to 8400 RPM, the E9X M3 is known for having one of the most unique V8 engine notes. Its high redline and individual throttle bodies create an amazing combination of induction noise and exhaust symphony. 

The first modification we recommend for the M3 is an aftermarket exhaust system. It is criminal to keep that exhaust note muffled by the factory system. The addition of an X-Pipe or full cat-back system allows the S65 to properly breathe. But don’t stop there, an intake and tune will go a long way for this motor as well, picking up some much-needed low-end torque. 

One of the more common issues on these cars is rod-bearings. While some people have 200k+ miles on their factory bearings, and others have had motor failure below 50k, it’s truly hard to tell if this issue is overblown or not. We recommend getting them changed every 60-80k miles in your M3. This will provide the most reliability and more importantly peace of mind while you enjoy your M3!

Looking to really spice things up on your M3? The S65 happens to LOVE boost, with multiple supercharger kit options available for the platform. 500whp+ is easily achievable and creates an extremely unique driving experience.
