Is it for a mk1 or mk2 Uno?
If it's a mk1, I think the turbo bumper bottom edge is about 1 or 2 inches lower than the standard bumper, hence it makes the car appear to look lower. You also get fog lights, or at least two spaces to put them!
It does look nice, and in my opinion a lot less over the top compared with some of the aftermarket (Novadose style) bumpers. Depends what you like I suppose!
I'm not familiar with the mk2 Uno's, so if it's for one of these you'll need input from someone who knows about them!
