Wheel fitment question

[LL - NY]

I'd agree. I've swapped between 45 and 38 mm (negative) offset on both
Audi's and VW's without any noticable effects. Some of the offset change
will be necessary in order to deal with the change in rim width's, (it's
moving the wheel out about 1/4" and at minimum, the new wheel is going to be
1" wider, so it's still a bit touch and go), but as Grant says, a large
change in offsets may make the negative scrub radius of VW/Audis become
neutral (leads to tramelinnig) or worse yet in these applications, positive.
And yes, positive scrub radii do successfully exist, think 901 chassis
Porsches (right, Paul? ;-).
