I had a shimmed diff and the driveshaft came out and spat oil everywhere as my mate is a numpty
Having the Nismo 1.5 is one of the best upgrades to the car, it is so predictable so far.... I havent pushed the car hard yet as i am a skirt but when i get the chance i reckon the diff will hold up great! It can be a bit clunky at low speeds but with solid arms and subframe collars etc that is to be expected...
