They will fit just fine. You just need some small spacers as the rear dampers are made to fit the USDM 5th gen Civics or USDM 3rd gen Integras.
We've had a bunch of track time on a setup like this and it hasn't fallen off or messed up in any strange way.
I personally don't like Zeal that much coming from using B2s, B6s, S6s and having spent some time in superfunctions. They're pretty damn harsh even with spring rates that didn't exceed 14kg front, 12kg rear.
FWIW, they felt more at home on the track - the B2s I expected to be more docile like the Tein HA, I had before, but they too, were fairly aggressive.
