OK, once again: 1. flatspot and flatspot-behaviour is quasi a necessary result of the tyre-physics in rF2. As a tyre is made of tenthousands of independent nodes that are all calculated independently, the tyre behave all different on any part of the tyre. 2. If you are able to brake properly but rattling is just annoying you when it happens, then turn up damping in rF2 controller/FFB settings. 3. If you feel it is much too sensitive when braking: a) turn down sensitivity of brakes ------> controls b) turn down brake pressure of given car----->garage 4. If you don´t get how tyres, braking and thermodynamics as a whole works, then c) use ABS P.s.: send hardware-config and settings if you have still problems.
