Topdeck front: C127S full cut until B hole
Topdeck rear: C127S no cuts
I liked to use only 1-2 Motormount screws. But i recommend to try also 1-2-3 screws. Depending on the drivingstyle it can be better/faster.

The car feelt even more sharp and allowed to push harder with even less risks. Avg laptimes and fastest laptime improved noticeably after this change.
