Bottoming and bouncing?

This is what I have so far on these subjects but one of them I’m not sure about…

  1. Down the straights I might hear a scraping noise especially if I brake at the end(dive) or accelerate(squat)

My ride height is too low, springs too soft either in rear or front or maybe even aero can help - less of

  1. Lets say I’ve made those changes and I’m happy with the straight, now I turn a corner and go over the curb and hey this feels good and smooth, another corner feels good also but then I hit another curb and bam my car is sprung up into the air.

Is this a combination of springs, dampers?

Is my ride height too low and my rebound too fast? I.e is the wheel bouncing up into the well and lifting my car or is my rebound too fast and my arb’s too stiff so the wheels are lifted, in turn-in, anyway and the rebound just finishes me off?

I can soften front but I dont wanna go too soft and sometimes when I do that he problem still exists…

What’s going on here and how can I fix it?

oh and lets assume my front toe is set to 0

I tried to address this issue since FM3 and it seems that there is no practical way to “tune” it out. This happens at places where you don’t think it would happen, eg. 1R at Silverstone GP, so it catches you by surprise.

I think the problem is lack of “fast” bump/rebound settings specifically for these types of bumps. I tried using soft springs/damper settings to no enduring success. And it seems to happen more frequently to the rear wheels. Softer springs and damper combo may reduce the bump shock to an extent but softer set-up affects handling therefore the suspension should be set-up for general handling, not for 1 specific corner. Smaller rims and lower pressure would also help but will NOT eliminate this condition.

I know of NO proven combination that would address this concern. Drove quite aggressively over the curbs at Long Beach last night and was surprised that the car just drove right over them with some air but completely to my expectations. And the LB curbs are pretty high compared to Silverstone 1R curbs.
