tm rims are the stiffest and strongest i have seen.. i raced all last year with no breaks, or chunks i the foam.. never before have i seen this.. to me that is worth it...
the tm rims are slightly heavier then the others.. but if u want less flex, u need some ore matirial... weight wise i notice no difference in performance...
at last years region 5 race for oval, tm tq'd every class.. and this was against a feild of some of the top guys...
