Hi not sure about the red ones but Powerflex do a range of stops http://www.powerflex.co.uk/road-series/products/Bumpstops-2666/1.html the ones that are marked K are expanded foam but the others are polyurethane which isn't great as a bumpstop material as it is much too stiff. If you come into contact with a poly bumpstop whilst cornering there will be a much greater transfer of weight than with expanded foam which are progressive in force/deflection. cheers Julian
