He merlin!
Nice list!
Can't believe you have to get balast!
Are you using waterless coolant? is it an option for you to switch to waterless coolant? You will need to flush the system but I think it will be worth it! As I have no fluids in the car I will use it from the start.
What camera and performance meter are you going to use? Im planning to fit 3 way fused 12V sigaret plugs behind my seat.
So it will make it easy to get a power supply for a camera etc.
Also I'm really starting to think about the rear upperarms.Got the standard ones at the moment but as you and Richy botch think the origional are insufficient I might be better of changing them. My suspention is way to hard so they will take a beating!
Good luck with getting the list done! And supporting your wife!
