willwood 4pot on jdm itr 1997
We have been running Wilwood Dynapro 4 piston calipers of years and I have nothing but great things to say about them...well worth it me (and note, we have run these on basic street cars and dedicated race cars, same happy end result)
Piston area and flex. Almost all of the Wilwood stuff for Honda's has a smaller piston area than the stock ITR calipers. This creates higher line pressure, and the Wilwood calipers being rather weak results in flex.
Stock ITR calipers on the front have 2550mm^2
Standard stuff for Integra's
Spoon Twinblock 4 piston are 2586mm^2
Wilwood Dynapro 6 piston are 1987mm^2
Wilwood Dynalite 4 piston are 1935mm^2
Wilwood Superlite aren't listed for an Integra to fit. They can be had cheaper than the others and come in a 2658mm^2 piston size. You can get the other calipers in that piston size, but I'm guessing custom brackets will need to be made. Also take a look at pad size. It is honestly harder to actually upgrade from the stock brakes as far as force. I wouldn't even consider the caliper weight as a negative and pad size is just fine. Rotor size with heavy track use is the only place I can see a flaw.

You can sit there an analyze those #'s all you want..I choose to use real world testing and experience so everyone can take this for what it is worth and I will specifically reference my Wilwood race car experience...not sure how many different brake caliper setups you have personally used but I can base this stuff on my own personal knowledge and feel.
I have never met anyone that has told me they like the OEM Brake Caliper feel more than a Wilwood brake caliper feel....sure, the piston/pad area may be smaller but I will gladly exchange that for the much more confidence inspiring brake pedal feel. Every car I have driven with the Wilwood 4 piston calipers has had better stopping ability than any of the OEM brake caliper cars.
I run the Dynapro's on our 2700lb EP3 that is quite quick in a straight line....we have never had to run any brake ducting or do anything special to the brake setup other than race pads and motul and they never fade and this includes hauling the car down from 140mph at Daytona for 1.5 hour enduro's.
I have never seen an OEM caliper setup that didn't need a lot of finagling to get it to last and work correctly and even still in a race atmosphere they leave some on the table for performance.
I would find it far fetched for the vast majority of enthusiast level motorsports participants to notice any brake caliper "flex" to begin with.
Finally, another reason that I will always run something like a Wilwood on my race cars in classes that allow them is brake pad cost.
Race Pads for OEM Calipers = $185+
Race Pads for Wilwood Dynapro's = $100+

Not all 15" wheels will clear....a lot of them fit very different so in addition to of course getting the brake setup designed to fit behind a 15" wheel you will have to make sure the wheel offers the clearance you need as well.
Here are 2 for your reference:
This is a Wilwood on a 4 lug setup behind a 15x7 Enkei PF01

This is a Wilwood 4piston on a 5 lug setup (actually on an EP3 currently) behind a 15x7 wheels
