The differences are:
front camber increased -0.75 degrees
rear camber increased -0.50 degrees
front and rear ride height dropped 0.75"
These differences are relatively minor, and there are many street cars running more camber than the track specs. Only you know where (and how) you drive and whether the reduced ground clearance is going to be an issue, but I'd go with it.
Having said that, how many vulnerable bits (e.g.
oil pan, bellhousing, etc.) does your car have that may be at increased risk if you drop it 3/4"?
