The F80 M3 CS<\/a> doesn\u2019t usually fly under the radar\u2014but this one somehow did. Painted in Lime Rock Grey Metallic and finished with motorsport-grade hardware, it looks like it just rolled out of a secret M division test facility. But it didn\u2019t. It came out of European Auto Source in Southern California. And what makes it special isn\u2019t just the color or the carbon bits\u2014it\u2019s the fact that it runs the Nitron\u2019s all-new elec-TRON R3 coilover system.<\/p>\n

Nitron has been quietly developing this electronically adjustable suspension setup to integrate directly with BMW\u2019s factory Electronic Damper Control (EDC). Translation? You can control the new coilovers through your iDrive screen like stock\u2014except they\u2019re race-grade, fully adjustable dampers. And this M3 CS is the testbed.<\/p>\n

The owner didn\u2019t stop at the coilovers, either. The car\u2019s suspension is fully dialed in with SPL\u2019s complete catalog underneath. We\u2019re talking arms, links, bushings\u2014all precision components that sharpen the chassis. And to make sure the back end stays planted under throttle, a Turner Motorsports diff brace was thrown in for good measure.<\/p>\n

This thing is meant to be driven\u2014hard. So it\u2019s not a surprise to see a full CSF cooling package under the hood, including upgraded radiators and heat exchangers. There\u2019s also an Eventuri intake system feeding cooler air into the S55<\/a>, and more importantly, a VTT crank hub kit making sure everything stays in one piece when things get spicy. Anyone familiar with S55s knows that mod isn\u2019t for show. It\u2019s insurance.<\/p>\n

Inside, the car trades the factory comfort for a serious upgrade in feedback. Sparco QRT-C Performance Carbon Fiber seats now hold the driver and passenger tight, mounted to Macht Schnell Clubsport mounts. Right now, they\u2019re bare carbon, but EAS says they\u2019ll be getting custom upholstery soon to bring a bit of civility back. Not that this car cares. A Madtrace\/JQWerks race steering wheel adds even more motorsport flavor\u2014complete with programmable controls and just the right amount of drama.<\/p>\n

It rides on a set of Titan 7 T-M20 forged wheels, chosen for strength and weight savings, and hides a set of Brembo Pista FF front brakes behind them. Rear calipers are on the way. For now, the car already stops like a doorstop hitting concrete\u2014EAS says brake fade isn\u2019t even a discussion point anymore.<\/p>\n

The project is still evolving. The seats will get finished, the rear brakes are on their way, and we suspect there are a few more things coming down the pipeline. But even as it sits, this F80 M3 CS is a seriously well-executed build with real vision behind it\u2014not just a shopping list of parts.<\/p>\n","protected":false},"excerpt":{"rendered":"
