Swapped out my OEM clutch line yesterday on DSOL with a braided stainless line from USP Motorsports. So far, it feels good, though the o-rings are at different positions on the line - one in the grove nearest the top, and another on the grove below it. The line that came off the car only has one position. The part of the line that goes to the clutch master is snug, but not as much as I'd like, but doesn't appear to be leaking. The slave side is pretty solid in its connection. Did a test drive and it feels good. Didn't increase my pedal travel as I'd hoped, but it still feels pretty good. Having been stranded before because of a leaky line, hopefully this works good. One of our TDI trusted vendors has the OEM line for $200 (NLA otherwise for VW), but I opted for the cheaper line, because, well, it's braided stainless, and I'm doing two cars ($67 each with shipping).
The car seems to shift just fine, so hopefully that fixes my issue I had in the past. Still waiting for one to arrive for DSEL.
