Ive just noticed something very strange: for the second body upgrade the car gets a PR rating of 85,3 with top speed of 444 kph and 2.52 acceleration but if you apply the secong engine upgrade the car gets a PR rating of 85,5 despite the top speed being only 443 and accel 2.53. wtf?! can anyone explain this?
