Love your reviews....GS250 comes with 4 POT front brake caliper stock - significantly better stopping power vs F10 528. GS is for drivers who like pulling NA engines to high rpm with wide open throttle . Once it goes past 4000 rpm...it is very powerful and sounds fantastic (Peak torque 4800 rpm) . In manual mode it can even blip throttle aggressively on downshift! NO SOUND NO FUN =)
