I pulled mine with only 60 k and 5k track miles with 0 symptoms and they looked like this .....
Get a blackstone oil analysis ,if you're lead is elevated at all replace them period . Honestly they WILL look bad if you have sig track time . The rod bearings on this car are a disposable wear and tear item , like rotors and are its engines only weakness . I also switched to Motul 300V competition 15/50 because of its much superior additive package and oil stability at high temps . The oil literally doesn't blacken even after multiple track days seeing 240 degree oil temps and has a TON of Moly which prevents wear if an oil does break down at a bearing surface . I'll post up my next oil change with the new oil and my treated bearings .
