Thinking of going for a Buddyclub GTwing, but i want the legs raised, as Scoobyclinic's featured car on Total Impreza couple of month ago. I understand it will add alot more drag, thus pushing/holding the back end down!!?? Will it hold the car back at top end speeds? Also what is the best angle to set the wing adjustment angle at? Could do with a bit more of a sceintific approach on the issue?

I love the look of them, but what is the all round best set up on GT wings, ie, height,angle,length ect?

Many thanks in advance guys
