I went from 15x6.5" ET42 -> 15x7" ET35. What a difference! Couldn't push it as the arches needed rolled proper however you could feel how much more planted the car felt, looking forward to driving it again now the arches are sorted
They would fit in there easy
Brembos require massive clearance, calipers are very wide as you can see here
tell a safe clearance between caliper and wheel.
a little stone can become dust i think on a rotating wheel imo.
Can you still have the whole of your inner wheel arch covers fitted or do they catch? Or rub on full lock.
Just thought when rolling the arches you might not be able to still use your inner covers.?
