Aftermarket speedo

[raggamuffin]

Can an aftermarket or race/rally style speedo be adjusted to suit larger wheels on a puma? I believe fitting larger wheels would mean your speed would show you were going slower than you actually were. I imagine these fancy speedos being as expensive as they are could be adjusted to compensate?

Also as a side note, how big can you go with alloys on a puma?

If you swap your wheels for different sized ones you can always check out your speedo with a passenger and a sat nav. Just find a quiet straight road and maintain a speed whilst you check the speedo and your passenger shouts out the sat nav numbers. My speedo now, with 205/45/17 tyres, reads virtually cock on what it's actually doing.
