So I have had a DSS 1 piece aluminum DS and a GForce 1 piece aluminum DS in my 2018 mustang 10r80 gt......both i had to pull out of my car because both vibrated....anyone have one in a 2018/19 10r80 Mustang GT that is smooth as butter? let me know, im thinking of trying the carbon fiber QA1 DS next but all this is costing me a small fortune....so far ive paid for 2 driveshafts, paid to have it installed and removed and stock reinstalled twice....I need one as i track my car and dont feel a stock one is going to hold up in an 800rwhp car with a PD blower in it....
