I took the zforce to the dealer to have a Stage ² clutch kit from Iron Baltic, spacers and 30 inch tires fitted. They found that the pulley on the primary drive had a crack. Today I went on a test drive and I have to say it drives much better. It was worth it!

Thank you for the information. But unfortunately that doesn't work. I think you need the Bosch ECU unit. But another solution would be cheaper!

Hi Folks,

How can i calibrate my speedometer?
Because i have spend bigger tires for my zforce.

Thanks for your Help!
