Great suggestion. Coming from an S197 I didn't realize how far the chassis on the S550 had progressed. To be fair, going from a 3 link leaf spring/mcpherson strut setup to MagneRide is quite the change in chassis technology though.Gotcha, this generation is just a different pony. Unless you've had an 04 Cobra, the IRS is a new element to account for. You're right that the PP/mag should be good to go for decent power. Might still want to look at something like Steeda's Stop the Hop kit. I'm personally going that route for my eventual FI build.
