I paid £50 for the work, cash. Took them half hour as it is the setup that takes the time. Tyres must be off though.

did they re machine the lead in?
Still things take longer and cost more dan sarf
You can do some wheels with the tyres on, if your machine is big enough, i have done S1  RS turbo wheels with rubber on but never D90s  so ill shut it

where do you live mate? i could do them for you for a few quid cash in hand. i wouldnt suggest doing them by hand tho, no chance of getting them true.
