I just got a set of the above. Anyone know how or where I can send the speedo to get it calibrated. 1300 Xflow RS2000 wheels. Or will it be OK - no idea what size tyres the dolomite had.

Cheers

I'd try speedy cables. They can recalibrate speedos and make up custom cables. I've never used them but hear good things about them all the time.

From memory my old dolly sprint had 13" wheels with 175/70 tyres.
