Yes it will.

And by the way, these 6 piston calipers are in another league compared to the GS F-sport calipers. We use Wilwood Aero 6-piston calipers, they are forged, *much* lighter, larger, 6 piston, truly a competition worthy top-of-the-line caliper.

We are testing the rear 4 piston 13.6" kit on the GS350 Fsport AWD next week, then we will be able to formally announce fitment.

One thing that we need to figure out is if the GS350 rear knuckle is the same as the 3IS rear knuckle in terms of mounting the rear calipers.... we would need to get a 3IS into the shop to verify, but my hunch is the GS350 rear knuckle is the same dimensionally.
