Ah too cool!
Scott, sounds like your issue may be better aleviated with an alignment change rather than a shock setting change.
You’re talking about at 50+ seconds in the video, where you begin to go down hill and you hit a right corner? Assuming that’s it, and I know you know this, but staying on power is going to stabilize the back end. However, if the car is still being upset by the bump in the road, there are a couple things you can try:
-
Reduce rear compression. This will reduce bump stiffness in the back and keep it more planted. If this is not possible, then see #2.
-
Increase rear rebound (this assumes rebound can be adjusted with little to no cross talk/affect on compression settings). This will stop the wheel from bounding back into the road too suddenly, causing a loss of traction at the speed and vehicle loadings you are seeing on that part of the track.
Now if you’re talking about turn 6 as you are cresting the hill, and there is a bump near the exit, the recommendation for the rear remains to be the same. For the front, I would increase rebound.
Try 1 change at a time though and note the difference.
I’d like to know more about what you are feeling the car is doing on entry/mid/exit of a corner (esp a trouble corner–outside of what a surface undulation would do).
That said, I would not setup the left side of the car stiffer than the right side of the car (or vice versa). You’d only do that on a circle track. The thing with a road course is that with funky asymmetric settings like that, it affects the car under braking, over bumps etc. Load transfer happens everywhere, and in a place as technical as a road circuit, you do not want an asymmetric setup.
Personally, I do not see the bump upsetting the car too much in the video–just because it’s likely one of those things that a video cannot capture. But in a transition going from uphill to downhill, you just peg the gas and hold on for life + deal with the rotation that may occur As you know, keeping the weight transitioned rearward is what you want to do in that situation.
Regardless, those are some smooth hands. Couldn’t say the same for half of the in car videos I happen to come across!
You are dealing with front end traction well in an understeer prone car. You’re also not giving it crazy steering input when it starts to push.
Also, considering that video is from a stock car, you are going to be in for a world of a difference with the RSS. Much better shock platform. If the RS5 OE shock is anything like the S4, it’s got too much bump and not enough rebound. You will have much more rebound control on the RSS. It’s going to be wayyyyyy more stable and consistent the next time you’re out. You’re in for a treat Would be good to hear what you think after you come back!
