After driving a high strung, feisty Zed 3 M Coupe for five years the transition to the Zed 4 M Coupe borders on boring. The car does everything you ask it to do in a very uneventful manner. I've done four driving school events with the car and it performed flawlessly. Install high temperature competition brake pads, mount R-compound tires, turn off the DSC and you have a thoroughbred stallion ready to go fast and take any turn you can throw at it. This one is definitely a keeper. BMW has raised the bar very high with the S54 powered Zed 4 M Coupe.
Great brakes taken off the E46 M3 CSL, limited slip 3.63 differential and very responsive steering. The S54 engine is smooth and produces linear from 2000 through 7900 RPM.
Better tires; the OE Contis are marginal at best. At least they're not run flats. The exhaust system is rust prone.
