Car drives great. Does seem to still bog down some halfway through the race like it has been doing since i flipped the diff to down. Cars pace still picked up .10 entire run with todays changes, but i feel it is still giving up some speed toward the end of the run. Next week tests : Flip rear diff back to up and work on car from there. Will probably need to lower rear inner upper arm down to calm car after flipping the diff. possibly go to 2 screws in motor mount and 2 screws in the T brace instead of 3 in each.
