i just tried mt new center smart diff in my 8ight-e and i must say im not impressed at all ive been using the smart diff for the last three times i went to the track and to be honest i cant get the car to turn as well as it did with the stock diff with stock oil (5000 i think) , first i ran the smart diff stock and it seemed to turn just a little less and accelerated about the same ,then i tried the next stiffer springs thinking it would free up the steering and it was a little better turn in but the front tires ballooned like crazy so then i tried the 2 .15 springs with 2 coils cut off and the car didn't want to turn at all and accelerated about the same as the stock diff and the smart diff would get noticeably hot when i ran it this way so i went back to the way it came out of the box .........to be honest i feel like it was a big waist of money i think im putting the stock setup back in
im running on a blue grove track on the tighter side so i thought it would help me turn tighter.......not
