I'm with you Seattle! That guy who used ARK supplied lowering springs says just the opposite but if you read the ARK website the manufacturer reports that the springs are firmer...yes firmer! I find my 2012 3.8 just right (may have a lot to do with the "passenger grade" Michelins). My Genie is in the shop for that intermittent DEAD audio bug and they loaned me a Sonata to drive (2012 2.0 turbo) and while the ride is certainly less firm than my Genesis the Sonata still handles bumps/road interruptions the same way as my/our Genesis with a big thud (rode in a KIA van and yes also very similar)...I think Hyundai suspensions across the board are similary designed to handle (or not handle) the big changes in a similar manner....now if ARK designs a progressive spring without lowering (I have NO DESIRE FOR THAT) then I would try it...just for shits and giggles.
I really would like to take a ride in someone's Genesis that considers it to be a "soft" ride. Any one in the pacific northwest area? Heck, I'd drive half way across the country for this.
I stand by my statement of it depends on your definition as I think the Genesis sedan has a very soft comfy ride from the factory, but I didn't come from a Big body Lexus or anything like that. Im used to being slammed on coilovers and air ride. Everyone has a different definiton of a "stiff ride"For reference my other car:
Really need to see photos of the hole set up as far as the bag over coil and what rear bag set up your running. reason being is I have someone interested in building an air set up for our cars but because he cant get his hands on a loner car for mock up and by looking at photos he feels that they would rub. So any and all specs and pics would really help.
