That is impressive weekly mileage to put up on a GTT.
I actually bought the speedlines years ago, there were up on adverts.ie, full set of 5 rims freshly powdercoated, no tyres or centrecaps. I got rainsports for them, a set of universal caps and got some speedline gel coated decals made up. I had them on my MK2 Jetta then for a few years (I'm also big into VWs)
Once I got the starlet I knew the speedlines had to go back where they were meant to be!
