Wheel spacers

[Crombievxr]

I have a 172 cup on trophy turini's and they seem to be lost in the arches. What would be the best size spacers for this ? Also would hub spacers be better for the rear ? Thanks

I have the same wheels, 16mm spacers at the front and 10mm stub axle spacers on the rear. I have 15mm stub axles on the rear and it is fine, others will disagree. I have bilsteins and the car is low but not slammed low.
