Lemforder is good stuff. Everything I've had from them looks identical to oem
As for geo.....stick to oem for a road car unless you really push it hard. Stock is zero toe, -0.55 front camber and around -2 camber at the back iirc.
The more camber you add up front, the more unsettled and twitchy (left/right tugging on uneven surfaces) it becomes in a straight line, but the pay off is in the corners.
Best way to judge your camber requirements is to look at your front tyres' outer tread blocks. If they're rounded off from hard cornering, you need more neg camber. If the wear is even across the tyre width, the geo is fine for your needs
MK5s run a lot of positive caster (+6 - 7 deg), which by the laws of physics = a lot of dynamic camber (road wheel naturally tips over as you steer - look at my sig pic), so they don't need much static camber adding, unlike older VWs with tiny +3 deg caster.
Sounds confusing I know, but there's a reason why VW set the front neg camber so low and trust in their judgement
What I would suggest is SuperPro ball joints so you can set the camber the same on both sides. Out of the factory, they have more camber on one side due to the slop in the subframe. Ultimately that just means cornering in one direction feels a bit easier/flatter than the other direction, but not massively important. Just a steering feel thing.
Absolutely get the arse end refreshed and aligned. You'd be surprised how much that end influences the feel of the front end.
