cool the rear differential

[Anonymous]

I have a thousand question this weekend I did a demonstration of drift and at the end of the day the final gear 4 / 77 with less than a year began to make noise like a whistle, then I wonder if this is not because of the oil temperature was too high???




Another issue with a cooling system at the rear, we must make changes al inside the differential?


thank you very much for your response is really nice
