Dynotorque in the UK is responsible for this swap. The E92 M3 6 speed is used which is basically the same as the E60 M5 6 speed however remember that was not available in the UK. The front crossmember was scalloped in order for the V10 to fit which it does pretty well along with the transmission. The stock E60 M5 headers are used and surprisingly fit although strong motor mounts were necessary as 5 mm of movement and they would rub. We would like to see what it puts down to the tire with tuning on the Pectel but can't complain, this is a very nice swap.
