Selling my CG-Lock seatbelt pre-tensioner since I haven't been to a trackday in years. Have used this half a dozen times over the years for trackdays in my old MkIV GTI and they are definitely a great bang-for-the-buck upgrade when you don't have harnesses to hold you in. Comes with the allen wrench you need to mount it and three different lengths of screws. Note that these do not fit the most recent fat seatbelt latches on Mk7 VWs, but fit most other seatbelts from the last several decades. Available locally or shipped, asking $50.
