Track plates rear axle Volvo 850

Tomorrow together! Does any of you have experience with it? Track plates at the back of the 850s? If so, to what width is it possible to do it without a sledge or even pull the fenders? Because it looks so narrow at the back of the ass… Now I want to make 20 aluminium plates per side on it, that it is at least a bit wider in the track… And because my 854 from the back has the look of the T5-R (spoiler, lamps, groin, etc.) looks like this shit, if it is so narrow there, zumi Have you ever had any experience of yours? Would all the tools in my workshop have been used to bulge, to pull the wheelhouses… So that shouldn’t fail… Thank you! LG Joe
