Thank you so much for the comments. I understand the car much better now, I wish I had known all this from the beginning. I hope this post helps others buying their first Team Corally. I already have everything I need to fix the minor issues on the way, and the EXB shocks have arrived me. I'm going to make the car even more amazing than it already is!.
Regarding the wing, from what I've seen, the Asuga wing is too big - 24.5cm, while the Kagama is 21cm. I think the Spark wing would fit much better, although I don't know if it will be stronger than the Kagama LE. I think the Spark wing size is 21.5cm, and it might not get stuck against the body. Can anyone confirm that the Spark wing (I think it's the same as the Kronos) measures 21.5cm?
If you know any other issues and fixes, please, write them in the comments. I will keep updating the first post.
Thanks!
