I have two installed in both Crossfires - The washers were the same thickness
150 miles last week in Tomahawk WI - Upshift is so smooth its incredible
I had my white spring adjuster backed up to the helix cover - At the same time i installed the shift assists i was playing with clutching on my C7
My wifes C6 clutching is stock other then the
[email protected] shift assist
So i left the white spring adjusters backed out initially
Well after a little ride i pulled out my spring tool and turned in the factory green springs about .25 from the helix cover
Backshift was amazing and everything was working like i had hoped - Even turning in the white spring adjuster is effortless - No more spring bind like you had with the black washer
And were you adjust it IT STAYS - No more white adjuster backing out on its own to the helix cover - Adjust it , play with it and it flat out kicks ass - That secondary spring will never bind anymore
Upshift/Backshift are incredible
