The Megans are the best investment I have made for car that made a big difference right away. I will be track testing them soon when I start autocrossing. The high spring rate does not affect the ride at all in our heavy car. I dont even find it necessary to set my shocks to the softest setting. I actually have them in ~the middle. Also if you go with the K-sport, dont make that decision based on the advertisement picture with the camber adjustment. It's a generic picture, the one for the supra would not have that adjustable mount. Hope that helps
