I was told from the dealer that my 04 MC had it but, they've lied to me before.... I do have the DCS toggle switch. Magic Mini told me that the rear sway bars are the same size as those on the MCS but, I have no stock MCS to check it out... Is there another way to tell? Thanks

 

Call 866-ASK-MINI and give them your vin. They should be able to tell you every option your car shipped with.

 

Sport Suspension is standard on a 04 MC.
Sport Suspension Plus is an option, and has the same

springs as the MCS.
