Yeah indeed, as I was rushing them to get it done within a couple of hours (wanna get it ready for morning drive) that pcs was definitely overlooked. I will have it adjusted next week cos it's CNY holiday here and no one there to help.

When I was running the 19s and even when I drive the loaner with 21s the car struggle to get grip, the traction control light is always on whenever I accelerate.
The aerokit is meant for better handling/grip and yes, it did the job well but yes, I think I did sacrifice some range but it's worth it to me.
The 22" wheels however makes the acceleration a tiny bit slower, that makes sense but it looks good!
I'll probably go with 21" on my D next time.
