For maximum positive improvement in comfort at minimum complication, you could go down to 6J to 7J wide x 16in wheels and use 205/60/R16 profile tyres (Octavia Scout wheel/tyre size), they will fit without suspension changes and provide big improvement in comfort, speedo will be exact. Note you need narrower and smaller diameter rims as well as narrower tyres. If you want to do more changes, as an example below is a setup for a 2016 Mk3 vRS that I own: It rides on narrow 6J x 17" black "Crystal" winter alloys (that are actually approved even for 340mm petrol vRS brakes) with 205/55/R17 all weather tyres (Michelin CrossClimate 2). Rear springs have been uprated by 2 groups to 5Q0511115AF (currently Lesjofors 4285741), and the rear shocks to Bilstein Sport B6 B6 24-229890. Note by far the easiest way to install new springs and shocks on multilink is to take out (and replace) 3 outer bottom arm bolts each side rather than mess with spring compressors. Also note front assist radar needed to be adjusted upwards by 1/2 turn. The 205/55/R17 tyre size is a Mk3 Scout tyre size. The higher springs together with slightly higher profile tyres make for about 1in higher ride height at front, and about 2in higher ride height at rear compared to stock vRS, I guess it'd be 1/2in over stock front and 1in higher back at rear when compared to Elegance. After 70k+ miles, the setup offers comfort, durability and robustness, even on very poor quality roads, it also offers somewhat increased ground clearance. Behaviour on motorway is actually better than stock, both for stability and comfort. Cornering is still good, unless you want track driving . Additional bonus is that when the car is full of luggage, it still has a good stance on autobahn which helps with air drag and fuel consumption, as well as stability at 120mph+ speeds (autobahn). This is not the first time I made similar changes, on my previous Mk1 Superb TDI V6 I had B6s all round, sport front springs, and HD rear springs and the effect was similar, drove over 200k miles in that one, significant part of it on shockingly poor roads.
