I do have coilovers which are narrower than normal springs.
You should be fine then, clearance wise. If you decide to bolt through the strut tops, you'll be able to get to the nuts fairly easily.
You can also mount with Rivnuts, that's how I did mine.
3 x M8 Rivnuts on each strut, bolted from the top - makes taking it off easier. (That's how it is now...it was different in the pic below)
Most should clear the TB OK, but you may find it hard to get in to the brake fluid reservoir without taking the strut brace off.
On Air Con cars you need to do a bit of trimming usually, and a bit of re-locating/bending of the air Con pipework...but it'l go.
You will have to make some form of bracket to hold the Air Con pipework though, or it'll virbate, fatigue and crack...a couple of little brackets are ideal, but you could probably Ty-Rap it to do the job.
The standard brackets will need to be removed if the brace runs hard against the bulkhead - as mine does.
See here for some idea:
