I never ran any rebound, ever.

Check chassis is brace properly and screws tight. When i drove an Academy SB-sport (shite), it was so flexible, when I went around the corner the chassis twist kind-of unloaded and flipped it in dramatic style - much like driving over a landmine.

Having more roll yes - can increase grip and cause more grip roll. Its the happy medium you need. As too stiff can make it fail to lean and just griproll instead.

if you can find a setup from Belgium GP, this track is insanely grippy and all astro, may help. I know I haven't ever driven the Bury new track but I have seen it (heck I work within 1/2mile of it as the crow flies).
