Strokereduction 0 Posted January 21, 2018 Hi guys 1st post but i have noticed that on race day the gear box wear will go up by a certain percentage as you start the race. I put a new gearbox in after qualifying and when i started the race it was already on 10%Also sometimes when you fit other parts they can have a random wear rate like i had a new mgu-k and energy store and were already on 52% they hadn't been used before i hope they fix this.
