front end spares is a must. the rocket shaped graphite part for steering, is (U3446). I also recomend the gear idler upgrade, ive only been racing for 6 months (SX2) and had to replace the standard idler twice, this is because the bearings have broke and all little bearings get stuck in the gears and chews them up.Havent raced yet with upgrade as only just fitted it. Also a spare diff and belts,not cheep, but if you are at the races and one gets a pebble or a screw in the housing you are bound to chew it up. What i did when i got the cat was looked out on ebay or oople for people selling second hand or new parts at a good price.hope this helps you and good luck.
