File this under “lessons learned” - if you rip a bunch of crap out of a race car that is still on stock suspension, you’re gonna find that it sits higher than it used to. Depending on the suspension geometry of the particular car, it might be very upset about that and it might behave in a way that you find surprising and/or unpredictable. If that’s the case, it’s best to address it before really trying to push the car. Noted for future reference. You are all totes welcome.
