Glanza v 1.3 gearbox breakage problem

[MineriX]

Hello guys, I'm new to the form. and i need help i have a glanzam and the gearbox broke this is not the first time this is the second time i am bored of this situation i can't put a locked gearbox too because i want to join time attacks with my car i want to join time attacks if i put a locked gearbox i can't enter the corners hard but the normal gearbox also breaks easily my car has a copper clutch and semi-flat tires What would you recommend, this situation has started to become very costly. Are there any suggestions to help? Thanks everyone

What is actually breaking on the gearbox?
Are you using a clutch with a sprung centre? This is a bit less direct, but absorbs some of the force before it hits the gearbox.
