I spoke to the parts guy today when I was at the dealer getting my free detail and he said that the coilovers listed on the site are for the MS6. The shocks have adjustable damping and if the springrates are not what you want, you can change them out with a stiffer spring at the dealer. How the spring swap works exactly, he did not say. But he said being it's a coilover solution springs are swappable.
As to the sways, he's looking into the sway kit as someone else was also asking about them here in Austin for an MS6 (anyone on this forum???) He will email me back as soon as the hears from the regional parts manager with an answer. He knows that they are thicker than stock, but he says it may only be a couple of millimeters thicker so handling performance may not increase or be only minimally better. I'll post his feedback once I hear from him.
