G6GT - being a person who regularly visits Treffen (if your so OMFG VW then you know what that is - I've owned a Corado, 1.8t Passat and a R32) I understand where you are coming from and understand the 'look appeal' to the situation and agree that yes - you can have improper offsets for FWD regardless of functionality.
The point we are trying to make, unless you decide to NEVER put down that hardtop (if thats the case, why have it) then your chill - but as soon as you displace the center of gravity and shift the weight backwards the offset is going to put more pressure on the spacers which (as your VW friends will tell you) are not the best idea due to their already large failure rate.
As far as your boyfriend VR swapping his Cabriolet, if it was the 1.8 4cyl it weights just under 500 lbs, the VR6 2.3 (1997 ish) is about 500 to 600 and the 2001+ has the 3.2 (Was in my R32) and it weighs just over 625 lbs - so that was a VERY bad analogy - sure he had to do some mechanic work but as far as weight distribution it was no worse then the weight of the back seat.
Long story short - from a fellow Vdubber - putting those wheels on your car will do more than just 'form over function'. As long as it sits still, you never move that roof down your fine but as all of us here will say over and over again
- Your boyfriend messed up - it's not going to work the way you envision. Period.
