Hate to butt in here with a old, dying topic but I wanted to post this.
Earlier in this thread there was a talk about spring rates and what determines that. One of the last things I said was I wish HPI would list the spring rates for the springs they sell for the R40.
Well guess what...
Toward the back of the R40 manual there are some specs for the car. And wouldn't you know it, right there in black and white, are the spring rates I was saying HPI needed to list. DUHHHHH
Ok HPI, I apologize...
So anyhow,,, back to what was being discussed here.
What's the physics behind aerodynamic??
