lol if he wants that much tell him to p**s off and buy a tullet
as matt did i posted the vid of the caliper rebuild and emailed it to them, they sent me a free set of seals for advertising
if he wants your car for RnD and then put stickers on it for advertising you should get a large part discount on the job
seems like a bum deal to me
tell him for £450 you want a full system , manifold to back box and you decide the size of the stickers
and then if its a good job you will post the info on the net for everyone to see what a good/bad job it is
