There is a write up on here
It’s the worst one on the car so prepare yourself
Look in the how to section- removing rear wing
If I remember right, you need to remove some or most of the bolts holding the hood in place (the horseshoe) then drop the hood half way
Then push the rubber weather strip away from the bodywork to reveal the last t30 bolt with very limited clearance
Round it off and it’s going to need an angle grinder…
