i discussed this rod bearing issue with 2 friends of mine who are bmw techs.they don't believe the earlier e90 m3's have a rod bearing problem.they just said the newer ones are tighter,and better suited for supercharger application.
if ess offers a kit capable of 775 hp on an 08 or an 09 with the original rod bearings,the motor must be pretty sound
Ha Ha, I don't think I would trust your friends, tighter is not what you would want for a higher horsepower application. You would want more oil clearance if anything.
