Recalibrating Speedo

[SilverShadow]

I have managed to get hold of 2 very rare original Hartge160mph and 180kph speedo dials.

Is there a way to re calibrate speedo’s so that it can work with these dials? E.g. Original 140mph clocks to suit the 280kph etc

Any information would be great.

Thanks

Or Have they just had the face changed for cheap ebay shit

Anyone?

My Speedo was reading 10 mph fast on my m3 160 mph Speedo due to a diff change. I swapped the face on to a 325 150 mph Speedo and it now reads correct. I suggest you research diff ratios or send it to a specialist.

I have aquired a Hartge speedo but mine is 180mph max speed, i did not realise a 160mph version was also made.

Diff ratio shouldn't effect what the speedo reads

Diff ratio wont affect indicated speed, its more than likely the wheels/tyres.

You can recalibrate, but need some very specialist tools which I dont know where to get.

Not sure ive seen any 160mph Hartge facias either.

Sorry to confuse the issue I checked the Speedo before and after with a GPS and it is close now. Perhaps. The 17 inch rims have thrown it out.

Do you have pics of Hartge 160mph speedo? I seen the Hartge 180mph on this site. I been searching for Hartge 300kmh. I found one in Hartge H35-24 e30 m3 diamond black. Here is a link.

I have 1 Hartge 260kmh and 3 Hartge 280kmh. The 260kmh is laser etched.

I had my E39 dials swapped over last year by Damone at http://www.sidmaster.co.uk/ and was very pleased with his work. Give him a call or email him, if he can't do it himself, he'll probably know who can.
