Sport suspension vs. "standard" setup?

You can get the sport suspension (if you're talking Sportline) in the 5 door here in Canada. There was one in Ottawa I was going to get but opted for the 3 door instead to suit my circumstances. With kids, you will not regret the 5 door!

Hey All,
I have the TDI Highline 5 door and although it comes with Sport Suspention, I personally think that an even tighter suspention would be better. The GTI is tuned in perfectly for feedback (many would suggest that it 'looks' to high, but rides great). Im putting in the H&R's this week in hopes of getting the GTI feel for the road. Ive never understood the anti roll bars. What are they limiting? To see the GTI being larger confused me even more. Thanks if someone can clarify.
