I've emailed alfa motorsports some time back.
They offer 2 types of wheel arch flares - medium/mild ones, and the full on sports sedans ones (featured in picture)
To the best of my knowledge (they also do front guards and bonnet) they only do one front spoiler. Good for racing, and ideal for putting ducts to route air to the brakes (and still allow adequate cooling) - Whether or not they 'look' as good is of course a matter of personal taste, it seems that their front spoiler has much less ground clearance (which is good for downforce/ground effect) and might end up in some strife with relentless suburban speed humps!
The two pics shown here are from alfa motorsports (amongst a few others they sent in response to a query a few months ago) - if they object to them being posted here, I'll delete them immediately (though I suspect if anything it might actually result in an order or two now that people can see some of their range)
