im lovin the idea of the drag set up... but i personally wouldnt put the stock bumper on... they add quite a bit of weight!
specially since your turboing, i think you'd do great with a set up like im doing for the front and rear, nice and clean, and saves on weight. check out the updates in my build if you havnt seen it yet.
either way, cant wait to run ya on the track this year!! see you in woodburn!
