Yes, Sport Suspension is standard on all 135 models. Check the default features: http://www.bmwusa.com/Standard/Content/Vehicles/2013/1/135iCoupe/Features_and_Specs/default.aspx?from=/Standard/Content/Vehicles/2013/1/135iCoupe/Features_and_Specs.aspx&return=/Standard/Content/Vehicles/2013/1/135iCoupe/Features_and_Specs.aspx
Also, note that the M Sport package does not include Sport Suspension on 135 models because it's already standard. Others can confirm and please check with your dealer, of course, but I'm 99.9% positive of this info. So ZED may end up working very well for you if you can live with the fineline wood trim (which I think looks amazing with the brown leather).
Just buy it and join the club, dammit!!!
