Lots of seat of the pants info but the only drag info was Middly and he had terrible times but that was with his cutouts and 21" wheels. Anyone...
I did have a 12.4 at 110mph with stage 2 and 20s....I haven't seen another F10 do any better than 12.4-12.7. like lacster said to me, you wont get any better than a .1 - .2s difference even with an added stage and he was exactly right.

My feeling is the car would do a 12.2-12.5 even with Stage 4. thats of course with xdrive.
