Any comments on which kit to get between the 12R5.2 and the CRC Xi? I'll be running at TQ (thanks for all the information you post, RedBull) and it seems both cars are popular. I'm leaning toward the 12R5.2 for parts availability, and I've always liked blue, lol, but is one preferred over the other? I know CRC has a new car coming out too, is it worth waiting for or should I just jump into one of these?
