While stock E30 suspension was touted at the time, combining front Macpherson struts with rear semi-trailing arms, modern suspension advancements have significantly outclassed 80s technology. A standard shock/strut combination is common for competitive E30 applications but leaves a level of customizability to be desired. That’s where E30 coilover suspension comes into play. Coilover suspension is…
Most owners of M54-powered BMWs will attest that the factory exhaust system is overly restrictive. The factory M54 exhaust headers are severely bottlenecked near the mounting flange, making it more difficult for exhaust gasses to escape through the exhaust system. Reduced power, torque, and throttle response are the results. Aftermarket, high-flow headers are the easiest…
Anyone that owns a BMW E30 325i knows that the factory M20B25 2.5L engine leaves a lot to be desired in the horsepower department. While the factory 6-cylinder is certainly enough to get a 2600 lb 325i going under its own weight, you won’t be winning any drag races. Other than adding forced induction to…
Generally speaking, there is a golden trifecta of modifications that can change the characteristics of your car dramatically: power mods, brake mods, and suspension mods. Of the three, suspension modifications are perhaps the most bang for your buck in terms of transforming money into enjoyment. This is true for most performance-oriented vehicles, F30 BMWs included….
E36’s relatively small and lightweight nature can make them fun street or daily drivers. However, with these cars pushing 25+ years old, a few upgrades will go a long way in improving the handling and performance of them. One of the best performance upgrades is replacing the worn stock suspension with a set of coilovers….
BMW S65 V8 engines are in the 2008-2013 E90/E92 M3. This incredible 4.0L engine is able to rev well beyond 8,000 RPM’s and delivers 414 horsepower. Solid numbers for a NA V8 engine of the era. However, some may consider it a little lackluster by modern standards. Not a problem, though. Those looking to push…
The S58 3.0 inline-6 has already proven to be the most capable production turbo engine from BMW. It’s still a relatively new engine in the G80 M3 and G82 M4. Flash tunes aren’t even available yet, so this post may be a bit premature. However, we’re too excited about the future of the BMW S58…
Prior to this article we wrote a guide about N54 fueling limits and upgrades. However, we didn’t dive fully into port injection (PI) since there’s a lot that goes into these setups. Those familiar with the N54 platform likely have some idea about port injection. It’s the ultimate fueling solution for those looking to make…

BMW N54 engines have long been known to deliver great performance with a few basic bolt-on mods. Simple bolt-ons for the N54 can push the engine to 400-450+whp with relative ease. Downpipe (DP) upgrades are among the best mods to take the 3.0L twin turbo engine to the next level. In this guide, we compare…

They also offer a handful of off-the-shelf (OTS) flash maps with tons of awesome features. Those looking to tune their S55 should…
Finally, we’re getting around to writing about water methanol injection for the S55 M2, M3, and M4. WMI acts as additional fueling for the BMW S55, and also offers cooler intake temps. There are several other benefits to WMI that we’ll jump into in this guide. However, there are also a few risks when running…
