So I want to go bigger to match the 276mm brakes. I heard GSR has a smaller master cyl than Evo 1-3 which must make it 15/16"? But same size brake booster. Also heard reports that Evo 4-5 will also fit, with the master cyl being 1 and 1/16" on the Evo 5/6?

In summary:

GSR Master Cyl = 15/16"
Evo 1-4 Master Cyl = 1"
Evo 5-6 Master Cyl = 1 and 1/16"

Correct? And the Booster is also larger than stock lancers, yeah? And I've heard tales of all of these being bolt-on with no mods required, also correct?

Thanks.
 
yes thats all correct. all evo models with brembos came with 17/16" mc's, the ones without such as the 1-4 and the rs models came with the 1".
yeah the standard lancer booster is a single stage, the evo ones and some fto ones are the dual stage boosters. pre sure its all interchangable. i'm using an evo 3 booster with an evo 1" mc, very nice firm pedal feel with good feedback. would highly recommend this setup. the 17/16" would be too big, and the 15/16" would still be very good but more squishy than the 1"
