Well balls i've knacked my car!!
Before:

After:

Was just coming back from a camping holiday in the lakes and going over the buttertubs near to my house, sharp bend, 100ft drop and my wheel falls off!!! Feel the crunch of the brake disc biting the tarmac and see my wheel rolling past me in a comedy manner before hurling itself off the side! Frickin' lucky was my first thought!
I'm putting it down to the ebay purchased wheel bolts i used to put these wheels on a few months ago. Couldn't find any to check though! I think i might have weakened them or something when i went over Hardknott pass the day before. (Does anyone know Hardknott? That is one SERIOUS road!)
Just about to pop it on axle stands and have a look at the damage.
If anyone has a Silver wing and/or door they would like to sell me that would be spot on! I have my old wheels and bolts to go on till i find the missing wheel

Going to check the brake disc but other than that there doesn't seem to be anything mechanically thats obviously damaged.
So yes if anyone has an ideas of things i should be checking, has a spare wing or door to sell me or just wants to offer condolences please reply!
