Keep in mind that you already have 11"+ OD discs and four-piston calipers (in front) as stock, so adding slightly bigger OD rotors of the same thickness gains nothing except weight, unless you remount new (or old ) calipers outboard to take advantage of the new rotor's extra area. Stock mount pad positions will not touch the added OD of big rotors so no leverage gain. DYI redrilling and tapping a new caliper mount pattern is not as simple as it sounds either, as the stock metric caliper mounting bolts thread into the stock forged steel steering arms. So, many kits use some sort of adapter bracket, which usually need shimming to center the opposing pistons. Shims should be included with the kit. If your area of the country has yearly road- worthiness inspections, there's the parking brake situation to consider...
That said, some Wilwood front calipers fit if you tap a third hole in the steering arms, but if you use an existing hole to make the adaption simpler, the spacing Wilwood uses pushes your new 2nd hole VERY close to the end of the steering arm. Being steel, you can do this, then gas-or-arc-weld a blob of new steel on the steering arm end where the new hole nearly falls through the forging, for safety. Smooth the weld off with a file and paint to look stock, then tap metric as req'd. Using (stock) gr-5 metric bolts means drilling your new Wilwood mount lugs oversize. SAE Gr-8 bolts fit the calipers but not the stock holes. I did all this to a pair of Wilwood Superlite 2 frt calipers some decades ago, for autocrossing with 11.5" OD adapted Porsche vented rotors, and no further problems. They are manually valve-balanced & will lock 245-50 front tires at any speed in a max-effort stop.
Note these are the widest tires that will fit uncut front narrow-body fenders, regardless if they're 15", 16", 17" or 18" OD tires. If you need more brake than this, you must be currently racing in a pro class & don't need this advice. If you simply want bigger brakes, that's a whole 'nother subject. Go for it!
