Brian, Ratman brings up a question, that I've been wanting to ask you. How does the tall rear spoiler not put too much down force on the rear of the car, and lighten the front end, especially at speed on the road course? It looks like you would need a bigger front spoiler or splitter to balance out the aero on your car.

Karl,

I was getting some really good rear grip on the sweepers. They are 75 - 100 mph or so. The way I have the car set up, just a little lift off the throttle would help turn the car. If you watch the video and listen to my throttle input, you can see how I did it. I was happy with the balance. It may not be ideal, but it worked okay for me. I have a larger front spoiler and I may experiment more with it next year.





Brian

How much does that rear spoiler deflect at speed? Thicker/thinner material could be used to tune aero loading at speed.....if it's legal. You could make a tattle-tale with a rod and O-ring to measure deflection similar to shock travel.

Good points. It does deflect as it is not super thick lexan. I have not seen a photo of the spoiler at high speed to see how much. The car was built primarily for under 80 mph, so I have not put a lot of thought into it.

Yeah Brian, I can see what you're saying about it starting the turn in when you lift the throttle. I can't believe how aggressive you were driving, even on the warm up lap. You sure made the most of that years worth of test and tune time.
