i'm soory for your DC2. The crash wasn't weard and the tires aren't the cause.
at the first corner your car have done a litle jump and in the second you haven't controled the force and the grip at rear of the first corner. so the car have the right line but when the force have works on the car, my mad happen this. LSD helps you in the bad think.
next time in the same case, turn more your momo and if you can't do more than this use a hand break.
