As previously mentioned, the left side arm lengths are the same. It is the right side that changed with the S7.
Warning: if you run your power steering pump up front, you will run into clearance issues with the new a-frame support and you may need to do some creative plumbing.
They'll send you the pieces if you want to do it yourself but we had them put it on the jig to be safe when we did ours.
With regards to the S7 in general, I'll say this: I found the car to be much more consistent and "drivable" in the center of the corner with the S7. It just felt like it reacted better to steering input and allowed me to be smoother from the center off. I've heard others tell me they noticed no difference whatsoever but I liked it.
For what it's worth, we bent a spindle one night last year and had to borrow an old style spindle at the track. We reset the ride height on that side to the old setting knowing that the spindle made a difference and just hoped for the best. The car was junk the rest of the night. There's a lot more to front end geometry than most people realize.
