Well Nubaru2 would certainly be correct on pre-2001. The GT had the larger calipers and roters. But according to my Legacy 2001 brochure it says...Brakes Front 10.7" vented disk, twin piston Rear 11.3". (to me this seems backward) It does not mention any difference between any of the Legacy models ie. GT dimentions vs. "L". So I take this to mean they streamlined production and put the same brakes on all Legacys. If this is incorrect could someone please fill me in. Thanks.
