I've had the chassis stiffening plate for a while now, and it did improve the handling of the car, especially with cross winds and driving over those nasty grooves we have in the concrete roads here, but improvement was still not where I wanted it. So yesterday put on a TRD Rear Sway bar and just drove it for the first time. WOW, quantum improvement, there's absolutely no body lean anymore and the wheels really feel planted no matter what I do. Now the car begs to be thrown around the corners and you just can't help youself stomping the gas at the apex for a good exit. Wow, just wow, I recommend you don't do this mod, mpg is really gonna suffer...........
