V50 Lowering + Track plates

Hello, I am driving a V50 with 17″ “Spartacus” rims and 205″ tyres. I have now ordered for front and rear 35mm H&R lowering springs. For my taste, the wheels are a little too far in the rear wheel box and I would like to build up a harmonious optics distance disks. I thought about 20mm per wheel (40mm per axle) the whole only back. White jmd if there could be experience with the wheel boxes in this combination? n Change wheel boxes and do without harder shock absorbers as well. Would be happy if you could help me.
