I've got BC's on my Hawk and so far so good. Ok, so you there are more expensive options that may well be better, but I've not found the BC's to be lacking at all.
I used
http://www.steeralign.co.uk/ for the setup. Matt is mobile or you can go to him if you want. He was British hill climb champion a few years back now and seems to really know his stuff. He has setup a number of cars in my local motor club and everyone I have spoken to says the results are positive.
