Kristine Rodas filed the lawsuit today ... claiming the Porsche Carrera GT Paul and Roger were driving had a faulty part in the suspension which caused the car to careen out of control. In the papers, she claims Roger tried to keep the car on the road, but could not regain control before hitting a light pole.
In the docs, filed today in L.A. County Superior Court ... Kristine also blames Porsche for the car exploding on impact -- claiming the vehicle lacked a proper "crash cage" and a "racing fuel cell."
Here"s the problem ... Kristine never acknowledges Roger was speeding in the car -- in fact, she claims he was only doing 55 mph. Back in March the CHP released its investigation results ... which put the car at somewhere between 80 and 93 MPH.
