I would have to agree with Psycho.
I had a TA03Pro with tons of Trinity Aluminum parts. I hit a curb while playing around and it cracked my front gear case where the my front arms attach to. The Aluminum did not give so something else had to.
Last month I had several bad hits to the left side of my current car a TA03R-TRF, but I was using the plastic arms and the only damage to my arm was a stripped ball connector for my front shock. Easy fix, just a little CA Glue and reconnect the ball connector. The Aluminum arms look really trick, I have the Cross arms as spares, but it all depends on what you want to use them for.

Cool you running tomorrow at Sheldons? It should be great place for your daughter to start racing. I would go, but I have a doctors appointment. I'll just have to wait until next week for Castle.
