Subject car is an '07 CS with a few mods: previous owner installed Billstein PSS 9 coilovers and rear toe links which allows the car to be lowered and have a nice bit of negative camber, at least in the rear. I'm running Nitto NT-01's, typically either white or black group at PCA events, advanced group at others, 8-10 DE days per year. I'm looking for an improvement that will help me maintain more momentum through corners and greater exit speed, so am wondering whether an upgrade to something like Tarrett Engineering front and rear anti-sway bars and drop links would be the next recommended mod? Or would I be better off going a different direction, with adjustable front lower control arms to get some more negative camber up front? Suggestions welcome.
