I first reversed into the garage, positioning it so that I had clear space and easy access around the car.
1. I raised the car onto two axial stands at the rear. If you opt to do this, you will need to ensure that the car is not too high to allow you to lean over into the engine bay, whilst it needs to be high enough to allow you good access under the car.
2. I then removed both rear wheels and wheelarch liners.
3. I left the jacks ( I have two) in place to act as a secondary support points - just in case
4. I then removed the diffuser and the middle section of the under-tray.
Note: If you choose to raise the car in this way, ie just the rear, please ensure that you have a pair of chocks under the front wheels. The car can move during the installation and this could result in the car coming off the stands.
Anyway, at this point, the car is pretty much ready for the work to commence.
