Frozen White M3 Sedan gets the Works
Most of our customers modify their cars in multiple stages, having us install one or two parts during each visit. Others, like the owner of this Frozen White wrapped E90 M3, want everything done in one fell swoop. So many components of this 2008 M3 have been replaced or upgraded that it's essentially a brand new car. It really did get the works.
The first order of business was strapping this sedan to our Dynojet to see what kind of power it was making. In its stock form this 2008 M3 recorded 332whp and 256wtq, which from what we've seen from dynoing hundreds of M3s, is on the lower end of the spectrum. We would soon fix that by installing an ESS Tuning VT2-625 intercooled supercharger system. To help the supercharger make even more power, we swapped out the restrictive OEM exhaust system with an Eisenmann Race muffler mated to a Macht Schnell Race catless x-pipe. After the installation and some 95 octane fuel, this M3 recorded 566whp and 364wtq, which is a very substantial gain of 234whp and 108wtq. It's actually making more toque at the wheels now than it was making horsepower at the wheels when stock!
Pushing this kind of power, the car was now in need of better brakes and suspension. A set of Ohlins Road & Track DFV coilovers paired with Ground Control adjustable camber plates was the perfect suspension upgrade for this high-performance sedan. To further improve power delivery and stiffen up the ride, we installed a full set of Macht Schnell solid aluminum bushing in the subframe as well as the differential. Yellow StopTech brakes, consisting of 6-Piston calipers with 380mm rotors in front and 4-Piston calipers with 355mm rotors in the rear, will effortlessly stop this M3 from any speed while looking great behind the HRE P40 wheels.
Inside, we removed the old iDrive system and upgraded to the newer CIC version. An AWRON Kompressor 1 digital gauge display was installed in the dash to monitor the supercharger's boost level as well as engine temps, oil pressure, g-forces and more. Because this M3 is equipped with a 6-speed manual transmission, we installed a Rogue Engineering OCTANE short shift kit in combination with a billet aluminum Ultimate Clutch Pedal, which both allow for quicker and more controlled shifts.
When this M3 showed up to our facility, it was a mostly stock sedan. By the time we were finished, it was an absolute beast. We took a ton of photos during every step of this build, so take a few minutes to look around. Enjoy!
