Finally, after nearly a year, I fitted the Juran seat rails to my Recaros. Fairly straightforward job.
The Juran rails are high quality, run smoothly and give a nice, low seating position. Much, much better than the home brew rails which I inherited in my car. In fact, they sit lower I think.
Only down side is that the rails don't leave room for the rear floor mats to sit flush, like OEM seats would.
Have pics if anyone wants to see for reference.
