mk1 wheel change

[mouthyman]

i have just changed my mk1 RSI (14") alloys for some OZ F1 (15") alloys, will this be ok for the gearing and speedo reading or will it need recalibrating, does anyone know the aspect ratio? or done the same thing on their car

the difference will be negligable, not worth bothering recalibrating really, speedos aint that accurate anyways.
