Looking at larger rims that stock and wondering how to correct the speedometer.

 

Look in the ETACS customization thread. if you want to do it yourself, you'll need to get the adapters and software...Vadimus is the guru in there. I do remember reading you can change tire size through it to correct speedometer.

 

Sorry but what is etacs?

 

ETACS is the computer that controls many functions of the car and allows the user/dealer to program specific options.
