They were reps. I clocked the weight difference as soon as I lifted one to put them in the back of the van. I just wished I had weighed them out of curiosity but I reckon it would have been in the region of 10's of kilos per wheel which is a lot extra to need turning and my remap is up to 213 bhp/440 torques. It just numbed the handling a lot and I only carry three mountain bikes or less most of the time.
The ride was fine, only rubbed on extreme rh lock (as do the OEM Sportline wheels). Fitting wise as well, the kit that came with the wheels had the RR to VW stud/nut conversion. When the RR wheels came off it was obvious that they were in the hub no more than two turns per stud!
If you do the same, fit the stud into the hub
then mount the wheels and nuts. My error was to fit the nut and stud together. When I tightened it up, all that happened was the stud went into the nut, not the hub, if you follow my thinking.
The recommendation from VW is 5 turns into the hub which makes a lot of sense.
It did look very good though, but I wanted to enjoy the drive and had been spoilt on the previously lighter rim/tyre combo, which was:
Hope this helps and makes sense!
