I had the 3 point snap-in, 2 inch harness in my 6th gen. I believe they are actually made by Schroth Racing. There was a plastic adjustment piece that broke on my driver lap belt, which would not hold the lap belt firmly. I had to get rid of it and buy another 3 point harness.
I went with a used set of bolt in Schroth Racing 3 point rallye, 2 inch harness that Lippstuh(i think) was selling. They felt MUCH better and more sturdy. Although, they are about twice as much as the rebranded "Sparco" set brand new.
** personally, I dont care for Sparco stuff. I think most, if not all of it, is rebranded. Thier harness guide bars are actually made by Speedware. Speedware sells them for $349. Sparco sells the same bar for $439. Apply a Sparco badge and viola -- you can charge $100 more.
