Regulation changes needs to be looked over

The new regulations changes are impossible to adapt!

for the third consecutive season the regulation changes comes just before the final race weekend and affects one entire department. Every part takes a minimum of 10 days to adapt and with only 4 available slots this is impossible to adapt all parts! I can only redevelop 4 parts, which means I need to redevelop the entire department every single season! 
this really needs to change now!
