The Fleetwood suspension set-up
I installed Impala SS springs, 'stiff' Bilstein shocks, BMR lower control arm and HO swaybars today.
I was pleasantly surprised out how comfortable the ride is. I would describe the ride as 'European' touring (the Euro's might differ and call it an softer American version.). Certainly comfortable enough for any grey haired old fart living in Florida to be envious of.
All I lost was the Cadillac 'float'. Which may make the passenger feel comforatable while he's sleeping, but as the driver of the car, it scared the heck out of me. The suspension floating around while I'm trying to drive the darn thing doesn't make me comfortable. Only proper car control makes me feel comfortable.
Next is 18" wheels and tires. This may make it slightly more jarring. But since this upgrade didn't increase the jar effect one iota, I'm much less worried about the wheel size now.
Anyone who says this set-up is rough or stiff, either lives in Iraq where the roads have some new large potholes, or they desire their road handling characteristics to mimic that of the Queen Mary. For everyone else seeking handling and comfort from an easy to assemble parts list, this is the set-up.
