yep....they have a firm outer&inner ring and a softer center ring....you glue those together and trim th ecorners at a 45* angle and put em in....they rock w/ stock size Bowties....I never smash Rims on my MT cause I don't use those offset barrels (40s) everyone likes so much.....IMO they catch more stuff and just don't have all that much of an advantage on an MT.......I like my MT to drive like a truck...I have a buggy for real racing...
