In all the years I tracked my car I never had it corner balanced. To be honest, as a weekend enthusiast I dont really see it being a necessity. If I were truly racing in competition then it would definitely be something you would want to do but I never was that hardcore. There are some weekend trackers who set their car up for all out race and that's fine. They want to maximize their track performance but I was just really out there to have fun. Oh, the Tein NAs you wouldnt have the capability to do that with since it doesn't have height adjustment.
