I saw an article on the Kelderman suspension upgrades for the F53 chassis and thought it might improve the ride. I'ts a bit pricey, but wonder if it's worth the $$? Can not find too many reviews or any recent ones.
Kelderman suggested doing front first as that makes the biggest improvement. Rear tends to be a bit more involved depending on placement of water, electric etc lines.
As I research this, it looks like Koni FSD shocks migth be an interum step. Also found that when I replaced the Goodyear tires with Hankook's that made a difference - they were not as hard(?). Due for tires soon.
Thanks to all who share their knowledge.
