The following question was raised but not answered in another thread about Prodrive USA having updated the wheel section of their website. So let me raise it again:
Why are the offsets on their (Prodrives) new wheel fitments for the STi so different from the stock +53? It's one thing to have a wheel that will clear the front calipers (I'm confident these do), but it's another thing to clear the calipers AND preserve optimum suspension geometry. A 9mm offset difference seems extreme to me and I am concerned about scrub radius and wheel bearing isssues.
I know Prodrive enjoys a great reputation in the Subaru community and they know infinitely more about suspension tuning than I do. Can someone explain why a 9mm offset difference is something I shouldn't be worried about? Thanks.
