When it comes to the BMW G80 M3/G82 M4, opinions are divided, particularly regarding the front-end design compared to its predecessor, the F80. However, I have to admit that the new look is starting to grow on me. The distinctive, aggressive styling that BMW’s M models are known for, combined with the powerhouse S58 engine, creates an impressive blend of visual and aural performance that certainly demands attention.
However, stepping inside the G80/G82/G84 reveals that there is significant room for improvement. With that in mind, let’s explore the top eight performance upgrades designed for the BMW G8X M3/M4.
1. CFS Radiators High-Performance Engine Oil Cooler
With many motorsports teams and racing enthusiasts now pushing over 800 horsepower, the S58 engine in the BMW G8X series often experiences oil temperatures well above normal. When these temperatures exceed safe limits, the G8X goes into limp mode, which can ruin a race, track session, or your overall driving enjoyment. CSF has developed a solution to keep your S58 running at peak performance.
By maintaining the factory mounting location and relative dimensions, CSF's upgrade allows the reuse of factory ducting and shrouds without any modifications. The S58 is known for its oil cooler sitting very low, right above the front splitter, making it vulnerable to damage from minor accidents. To address this, CSF has added a rock guard to protect the cooler. This enhancement helps prevent the oil cooler from being punctured by road debris, offering you greater safety and confidence that your oil system is protected.
2. CTS Turbo Downpipe
The factory exhaust unit was not built with optimal performance in mind. Manufactures have various factors they take into consideration when designing an OEM exhaust system that come before performance, such as cost reduction, sound deadening, etc. All of these compromises come with a price, they typically reduce performance. This Meisterschaft Downpipes replace the restrictive factory units and increases exhaust flow by minimizing bends in the system. With a better flowing exhaust you have faster throttle response and more power. Utilizing the highest quality 100% Stainless Steel. Along with better performance, the increase in exhaust flow also provides a louder, more aggressive tone over stock. Meisterschaft’s design team builds their exhaust systems to compliment the power plant of your G80/G82 and increase horsepower and torque.
3. Burger Motorsports Performance Front Mount Cold Air Intake
Finally, an intake system worthy of your S58 G80 M3 and G82 G83 M4! The Front Mount BMS Elite G8x S58 Performance Intake completely removes the restrictive OEM intake and replaces it with 3.5″ high flow ducting and BMS inverted cone performance air filters. The filters are placed behind the front grilles for maximum cold air induction, amazing sound, and intriguing looks. In addition to freeing up power, turbo spool speed is greatly improved and there’s an incredible sound improvement. You’ll finally be able to hear your turbos spooling!
4. KW Suspension V3 Coilover Kit
Exquisitely crafted in Germany by KW automotive, the KW V3 Coilover suspension kit is more than just a set of parts—it’s a true fusion of race-track technology and everyday driving thrill! Adjustable compression and rebound dampening paving the way for an exhilarating ride. This isn’t just any suspension upgrade; it’s a gateway to a whole new level of street performance. Increase tire grip for sharper corners by adjusting compression, all without sacrificing that optimal rebound damping. It is safe to say the KW V3 Kit is the Holy Grail for performance enthusiasts. So, buckle up and get ready to transform your driving experience—because with the KW V3, every ride becomes an exhilarating journey where performance and control meet in perfect harmony!
5. CSF Radiators High-Performance Front Mount Heat Exchanger
Like many BMWs, the S58 motor has some heat issues under heavy driving conditions. While in stock form, the G8X’s factory cooling system does a decent job keeping up with the cooling demands. While this was true of the car in factory spec, those results changed when the cars were modified and started pushing more power. CSF’s industry-leading reputation and deep knowledge of high-performance BMW cooling systems allowed its engineers to immediately identify the cooling weak spots on the S58 engine. The engine is very similar to the B58 in the A90 Supra and G-Series BMW 40i models. Both feature a liquid-to-air charge cooler manifold paired with a front mount heat exchanger (water radiator). The Heat Exchanger cools the fluid cycling through the charge cooler, dissipating heat from the system.
6. EBC Brakes High Performance Brake Pads
Are you planning to switch gears from commuting in your G80/G82 during the week to hitting the track over the weekend? If so, upgrading your brake pads might just be the key to elevating your driving experience! The M3 and M4 models are revered for their thrill-seeking drivers who crave optimal performance both on the road and the track. Recognizing this demand, EBC Brakes has unveiled a brand-new line of high-performance brake pads tailored for all versions of the G8X BMW M3/M4 lineup.
One of the common issues among the M car owners are brake squeals, which can hinder the overall driving experience. With EBC Brake pads, there’s no need to compromise by braking later and pressing the pedal harder. These high-performance brake pads are engineered to minimize noise while significantly enhancing brake performance. If you’re seeking a balance between reduced noise and superior braking capability, EBC High Performance Brake Pads could be the ideal solution for your M3/M4
7. Meisterschaft Titanium Full Catback Exhaust System
Take your G8X M3/M4 to the next level by adding the Meisterschaft Titanium Full Catback Exhaust System. This system is a triple threat; it will increase your vehicle’s power, reduce weight, and improve the overall sound to transform your driving experience. This precision-made performance system delivers more power, especially in the low- and mid-rev range. The effect on the sound is also significant, adding a deep resonant sporty sound, but at the same time neutralizing the vexing frequencies in the most critical rpm range. Complete the look with the choice of four different exhaust tip options: Stainless Steel tips, Glossy Black tips, Matte Black tips, or Heat Baked Dry Carbon tips.
8. VR Tuned Tuning Box
The 3.0L Twin-Turbo inline-6 S58 that lives in the engine bay of the M3 and M4 G80 was just as stout, if not more so than the B58 it replaced. While the highest numbers we were able to draw out of the stock turbos and this extremely reliable engine will remain top secret, we can proudly say our VR Tuned Tuning Box was able to achieve a peak of 640hp and 559ftlbs of torque while maintaining safe ignition timing and without increasing knock to a dangerous point. Additionally, due to the plug and play nature of the VR Tuned Tuning box, you can gain up to 137hp and 80ftlbs of torque and may even be able to maintain your factory warranty, depending on your vehicle’s point of failure and the dealership which services it.
While the new BMW Engine Computers do have the ability to datalog to identify issues or anomalies in a vehicles performance that would surely reveal ECU tampering, since the VR Tuned Tuning Box is plug and play and can be uninstalled without a trace, it’s safe to say uninstalling the Tuning Box and unplugging the battery for about 10 minutes should be enough to lose any datalogs and allow you to drive to your service center as stock as the day it left the plant. This of course, is just theory and not instruction.
So if you’re interested in gaining horsepower, throttle response, and increasing those much sought-after burbles from your exhaust without completely forfeiting your warranty by opening the ECU, look no further than VR Tuned.
