Been told to get suspension then wheels but what suspension? Had/got coils fk street on mk4 all wound down. I need comfort or a little softer than what I got on mk4 now as its everyday use with 18s
Who told you that?
They are an idiot.
The Mk6 is in a different league to the Mk4...the Mk4 is an ill handling, understeering barge with wallowy, under-damped suspension and ARBs made of string.
The Mk6 handles properly...so you don't need to change the suspension in order to make it corner.
I'm not surprised you had hard suspension on your Mk4 if you have cheap-ass FK coilovers wound all the way down.
On a Mk6, you need to do nothing for road use.
Lower it 20mm or so on quality springs if you want it to look better...but anything other than that, for road use, will ruin it.
Seriously, anyone that told you a road going GTI/GTD Mk6 (with properly designed and damped suspension with a multi-link back end) 'needs' suspension is a fool who hasn't got a clue what they are speaking about.
