Make sure the car is on a 100% flat surface or it will look a miss.
I have this and its generic if you google it its mentioned as the classic lean.
The car was built higher on nearside for u.s market to allow for the drivers weight you can remove it as i have with spring pads.
You may find its approx 10mm different i have a 5mm pad nearside and a 15mm offside and the car sits level.
Its not spring related as i swapped them and its the same.
I thought it to be rear subframe but reading up on it not sure its the case.
