SuperPro are great. +1 degree caster. Or Whiteline for +0.5 deg caster. Both work well but the Superpros probably last longer as the 'bearing' part of it is stainless steel. Whiteline's is poly on poly, which isn't brilliant for lifespan but works OK. Caster for those unfamiliar gives better turn-in and increases dynamic camber. Also improves straight line stability and reduces wheel hop. The more the better - but at the expense of steering feel and weight. Stock caster is ~7.5 degrees for reference.
Top mounts - I'd go with TTRS, or if you're feeling flush, Ground control. The less squidge you have up top, the better the components down below work
The Ground controls like a lot of other uber money MK5 tuning kit is a leap of faith thing. Hard to justify on paper but when all's said and done, brutally effective. What was it Rolls Royce used to say, "Quality is remembered long after the price is forgotten".
The VWR kit works great. Done about 1500 miles on it now and little to complain about, perhaps a little soft for me past 7/10ths as already mentioned. I am a bit of a hooligan in the corners though. The damping feels spot on matched to the springs, but progressive springs can be a little unpredictable in the corners at times, but fantastic for ride quality. OEM springs are linear, and with the aggressive OEM damper valving, it all feels a bit wooden and lumpy. With the VWR complaints, I am talking really pushing the car hard, way harder than you would on 90% of your regular journeys
The most important thing is it instills confidence. Many a time I've driven in cars with expensive, super hard suspension and not felt confident to explore the limits because it's so frickin crashy, hard and bouncy. Yes Bilstein PSS, I'm talking about you!!
