the racer series should be 7075, the regulars are probably 6061, anyway, that thing is ugly, honestly, fiorni dosnt make that great of parts, the ano chips REALLY easily, if you get a lot of strong chemicals on them the ano will have a weird look to it, the only things that are good from fioroni are their clutches[not the greatest but....] chassis, diffs, and there clutch bells and brake pads are ok, but not worth their price,

there have been to many people at our track who buy the full fioroni uniform for their 7.5 or x5 and take most of it back off, i was infact going to buy all the fioroni stuff until 3 people told me to go with the Racers Edge parts, so i did and have been very happy
