the wheels i made for my RCM.5 use the OFNA truggy dishes with the trinnity ultra firm truck foams i then cut 1/2 in from the width so they fit a buggy width wheel.then because i run on a track and almost never bash im using 1/10th truck double dees or hole shots.this combo gives a wide offset and the stiff foams hold up the sidewall in hard corners and my truck realy likes them
