From what I could read Marc and Wilck ran the stock 511 except for the gray ballcups. Dont think all of those options are that necessary accually.
I have seen your 511 Fredrik and you ran the same setup on both gravel and turf without any change, and the car was ACE on both tracks! Think that speaks for it self
. Your car looks like it so very light because it rides the bumps like they are not there and it so smooth all over the track. A 50/50 weight distribution without adding any additional weight any where is also impressive. With LIPOS!
Please correct me if I am wrong on any account.
