Shock absorbers Bilstein or KYB

On my 2019 GSW 4 Motion, I’m running Golf R springs F & R, Golf R RSB, and B4. With Continental Extreme DWS on 18” wheels, the ride, turn-in, and overall handling are very reminiscent of my Gen VI GTI.

After a few hundred miles, these Bilstein 5100s feel night and day better than the old Dobinsons. I know it's not apples to apples, since the Ds were bottom of the line and 5100s are presumably mid, but they control the body roll and bounce much better. The old ones were pretty stiff unless fully loaded, but these Bilstein are pleasant when empty and supportive when loaded, can't wait to upgrade the fronts!

Definitely go B6. B4 is basically stock. B6 is performance improvement but like, balanced. OEM+ performance improvement while retaining comfort.

Get bilstein B4 OE shocks. Decent price and will ride like stock.

I like my Bilstien B8's, made for lowered cars.

I put Bilstein b6 on mine but you’d have to probably do the front too if not going with OEM stuff. I also put 034 mounts which are fine on the front but I’m about to go back to stock on the back due to noise.

my e91 has bilstein B6 with stock springs and it rides great.

I installed stock(unmodified) Bilstein B4 shocks/struts on my 2017 REX with 19” wheels and the improvement was noticeable. Overall the ride was less unsettled and bouncy.

Note 5100s are not soak up the bumps kind of shocks. Depending on what you think is atrocious about your current ride, it might not be an improvement. My 08 V8 feels stiffer/sharper on bumps compared to OEM shocks, though it handles them with better composure, less resonance/vibration on hard hits, and handles washboard and bumps better. Also less body roll.

I had a 2018 Z71 and went with the Rancho RS 9000XL Quicklift. Was a great setup. I now have a 2020 AT4 and put on a set of the Bilstein 5100’s. Don’t like them at all. Ride quality is not much better than the factory and I still have the rear end hop going over bumps at speed.
