Good article... Lang Racing is on my way home from work... Maybe I'll pick their brains a bit regarding this... I know however they havent worked on very many E90 M3's... But I am sure that will change soon enough.
I called them before about coilovers, corner balancing, and a track alignment and they where a wealth of knowledge
The question I have for myself is.... 1) do i want to just change bearings as preventative maintenance? 2) have the engine re engineered as Lang racing suggests while using a modified factory rod? 3) enjoy whatever life my car has left and trade it in for something else in a few years
I dont like the last choice cause the soundtrack of that S65 V8 is so full of awesome
