M2 vs M140i battle (with banter) Bedford Autodrome Trackday 

It isn't the car, it's the driver that counts! My mate Sam is very handy behind the wheel and despite the 'lesser' car, he really did keep me honest! M2 clearly faster on the straights but Sam's 'driver mod(!)' is reeling me in most of the corners!
M2 - full tank of fuel and passenger, 400ish bhp
M140i - driver mod, LSD, camber, Hankook tyres
