Yep, the VWR dampers are quite a recent thing, and by most accounts do the job rather well with different brands of lowering springs as well as the VWR lowering springs themselves.
You'd be wise to replace the shocks if you're going lower anyway - standard shocks in good nick start out ok with lowering springs but quickly get rough. Reduced strut travel will guarantee a shorter life for your dampers.
As an example, I put mine on H&R springs (30mm drop) on my standard dampers at about 74k IIRC. No real reduction in ride quality at that point. Fast forward to today on 80k and things are definitely getting a little fidgety. I'm personally 50/50 on whether to go for some decent coilovers or just renew the dampers. If I go for option 2 it'll be the VWR dampers.
If you want to go a bit lower than the 20mm drop of VWR springs, there are two other tried and tested spring kits. One is the H&R set I'm on, the other is Eibach. Both kits drop roughly the same amount, although to my eye there are subtle differences. The Eibachs seem to give a little more forward rake - arch gap at the back is a bit more than H&R, and the fronts seem maybe 5-10mm lower. H&R give a more level looking stance. Either way, as spring kits go they both provide a nice stance.
If you want to go lower than 30mm then coilies are your best bet. Like I said, I'm currently flirting with that can of worms. We'll see what happens.
