Ok, so I've gotta ask if that narrowing of the A arms will change the suspension geometry?

On one hand it seems like it would HAVE to. And that could be a bad thing.

On the other, I'm thinking the attachment points are unchanged, the arc the A arms swing through as the springs compress/extend is unchanged...well, except for the distance from the pivot points...hmmmm?

If the fabricator is extra careful to make the modifications EXACTLY alike - and I'm sure you did - very nice looking mod by the way.

Anyone extra knowledgeable about suspension geometry able to provide some insight?
