Was just testing the Boxer and one minor, short lock up immediately produced heavy cockpit shaking/trembling due to flat spotting (i presume). It lasted for the whole lap. The effect is quite annoying and i suspect the effect may be exaggerated here. Does flat spotting really occur this fast on a car like the Boxer (notice the same pronounced and immediate effect on the SuperV8) and would you really notice it this much ? Cheers
