S3 rear is no use to him Gazz, kind offer though.
S3 front bar is the same as TT front bar, don't worry about that. Size MIGHT be slightly different, but shape and fit are identical.
As Jay's pic shows, you can use the standard droplinks to mount it all up, but it puts the links at a crazy angle, and the bushes won't last long AT ALL.
Best thing to do would be to space the top of the link inwards so it sits a bit better I think. If you spaced it inwards it wouldn't matter if you used std links or your adjustable ones. You'd want them pretty short though or you'd be moving the ARB up closer to the driveshaft.
If course, if you want to do it really properly, and never have issues again, an S3 front strut/coilover is the answer, using S3 droplinks, but I'm guessing from the nature of this post that you've recently lowered the car, so that's probably out of the question, unless your new shocks have the tab on the strut body
