Thanks for the tips. I will try those diff oils in the future. Can you post a pic of your GTP2E with the body on to display the aerodynamics?
I have tried the XO1 wing before instead of the stock wing and my car kept losing control or was hard to keep straight when accelerating hard. My guess is that it was caused by the decreased downforce in the rear from the XO1 wing. But I think top speed would have been higher with it.
