Shyguy 782 years ago000If I don't like the original supplied seat I can take any one and change it with two holes on the side..e.g. Sparco etcShow in original language (German)Anonymous2 years ago • purchased this product000purchased this product Helpful answerYes, they are standard rails and have 4 holes for fixing to the side. On the other hand, the seat is made of very good quality fibreglass. The price of the gt3 seat is much cheaper than a sparco fibreglass seat.Show in original language (French)CommentLostimPark2 years ago • purchased this product000purchased this productIf the holes fit then yes.Show in original language (German)Comment
