Hi Mate just looking at the thread again and on your front wings that you made a good job of putting the bubble in are you going fully widetrack this is because i see some guys have wrc wings on standard cars but they are not full wide track i have a set here off a white car that has the bubble rolled in it but are not any wider than a standard wing due to it not been cut where the sidelight sits this area is widen by 30mm giving the wing a wider track pics below one from the wrc book i have in a3 i have mark for you to see the item added in and then my wing with the added steel piece welded in
