Jonny, I feel your pain.
Even with the advantage of being able to stop down over my lunch hour and bullyrag them - they're just down the road from where I work - and despite having literally hundreds of rims in stock waiting for centers, I was told 1 month at the beginning of March and they weren't finished until late July.
His priority is roundy-pounder wheels, and once stock car season starts, everything else seems to go on the back burner.
I eventually got mine - well built, balanced up okay - but the frustration of the empty promise regarding delivery has convinced me that if I ever need another set of wheels, I'll explore other options.
