Hello together, I am driving the Mirzam 18 inch rims on my C70 at the moment. I would like to do a track widening on the HInteraxe now. I spoke with a tuner and if I only widen 20 or 30 mm, then the existing standing bolts have to be replaced, which costs again unnecessary workshop-hours. Now a tuner recommended the 40mm widening. with this the Volvo bolts are fixed within the widening with retractable nuts and out of the widening new standing bolts are available for the wheel assembly. My question to you… Can anyone tell me if the 40mm still fit into the rear wheel box? I (and the TÜV) have no interest that the wheels will be grinding or additional work required. I have Mirzam mounted with 235 maturation. many thanks for your help. frank P.S. Can someone tell me what the load in Germany at TÜV cost about ?
