I went for the 22mm adj rear bar along with front/rear d/links and h/duty bracket ( Classic )..Sorted the car out no end..
I didn't feel the need to fit a front bar (mentioned above) as it was never going near a track so it seemed a bit ott for my driving style.. Aren't 24's and front bars for track anyway ??
I started off with the bar in the middle setting and never tried it on the hardest setting..Trial and error i suppose, depends on how you drive and how you like the car to handle..
I'm sure i got mine from D/tweeks and asked for a Dave Featherstone(?) ..He usually deals with the group buys from s/net and gave me quite a good wee discount..Didn't see cheaper at the time..
