Hello, I bought the Gap tool to recalibrate my suspension on 2008 rrs, according to the information I have found it should measure 461mm or 18.1 inches at the front and 465mm or 18.3 inches at the rear. When I connect the Gap tool the picture shows numbers around 220, can anyone explain is 220 mm or inches as it doesn't make sense to me, I managed to calibrate to 181 at the front and 183 at the rear but the warning light came on again (amber) see photo attached. I need someone who knows how to use the Gap tool to give me step by step instructions to recalibrate, please can anyone help!!!

Not sure if this is any help but might be worth a look, seems to be page 102 onwards for suspension calibration.
