I'm also not using any personally....
I looked into this quite a bit as they came reccomended by quite a few people when I looked into it with my TTT control arms aswell. When I went to Wheels in Motion I chatted in length with Charlie who setup the business and travels the country teaching people how to undertake wheel alignments (he really knows his stuff when it comes to alignment). Based on the angle of my control arms he saw no benefit and suggested that it would be overkill for me, what sort of angle are your control arms?
I'd say that my car is fairly low while still being practical, it also depends on what size wheels you're using as I do know quite a few people with clearance issues using 15 inch wheels and below....
With 16's I'm fine however they just don't seem necessary, my arch gap allows me to get my hand in between the tyre and arch. My car is certainly a pleasure to drive and very responsive, if not a little agressive and playful at times. But that's why I love it
I may also have a photo of the rear if you want me to dig it out.
