Your going to see more rota's because they are cheaper to buy new than a proper competition wheel. Real aftermarket competition wheels are pushed through major testing facility's through 100's of youtube video's a forged wheel aka not a rota wheel already has more tensile strength than cast iron, fact, therefore they will crack before a genuine one will, the proof is in the metal it's pretty valid. The stock cast OEM wheels comparison is pretty invalid as rota advertise them as a aftermarket product they will stand up to general road test but I bet there not competition tested I'm off to bed rota's are gash end of story!
