The hangers are made by a compnay called Harris (dont know if your able to source their parts in the US) Cost me £70 for the pair. Well good quality.
And that number plate is massive, your right. I've changed it since that pic was taken so its a lil bit smaller. The cops over here love pulling you over for things like small plates so its best to not go too crazy on the smallness. Although they'd probably find it tricky to catch you on a SP1 if you didn't fancy stopping!
