I am happy with my gear diff.
I am putting the exotek knuckles on today.
It should help with keeping consistent/even ground clearance front to back and side to side. My old knuckles weren't set correctly because of a stripped grub screw hole on the collar.
And my front spoiler was dragging and one corner caught tape on the carpet and the car launched into the air and did a 5 yard long jump. After the race I used a heat gun to get rid of the downward curvature of the spoiler so it stays flat/horizontal.
