Please can anyone tell me the impact of changing from 16" wheels and tyres to 15" wheels running Avon CR6ZZ on the standard Mk4 speedo? Thanks.

You can work it out yourself using one of these calculators( many online):

Thank you, I wasn't aware of the calculator on line but now I've checked it it confirms my own calculations, which is helpful.
