Application intended for: E90 M3, E91 M3, E92 M3 from 2007 2008 2009 2010 2011 2012 2013, 2007-2009MY cars require update of rod bearings to new BMW specification before installation of this kit.
If it's under warranty & you decide to keep it, have BMW fix it under the warranty. If your car is truly stock & their was a significant mechanical component that caused premature engine failure, that should be covered under the BMW NA warranty.

If the car is no longer under warranty & you've got the funds, I'd say crack the motor open & lower the compression. Since you mentioned supercharging it as a "winter project", go all out & make BIG power
