The only concern I would have is based on your pad choice, not caliper choice (as some others have said, I agree and I think your seals will be fine). If you fit racing pads on your calipers, for street use, there might be some issues.
I run some extremely agressive Carbotech pads on my Z race car. On my out laps before race start I concentrate on getting the pads hot because they stop VERY poorly when the pad is cold. So poorly that if they were used in street driving you would definitely need to adjust your braking to not hit things, as I've learned the hard way with those pads. If you used a pad like that you'd never get them up to temperature in normal street driving, unless your normal street driving involves repeated stops from 100 mph in rapid succession.
So, I'd think you wouldn't have any problems with the "competition" brakes, or any brakes for that matter, as long as you use some discretion in pad choice and are honest on intended use.
