2017 infiniti Q50 AWD
If you think you’d utilize the difference of a 10x price point on the street go for it. But You already paid probably $2-3,000 more for the stock RS suspension when broken down price per component, so you may as well continue to utilize it by replacing the cheapest portion of it (the springs)I may go for a full package solution and install DDS compatible coilovers to avoid the headache. But again, price point. I don’t see myself tracking the car so it begs the question of whether or not that investment in full coil overs is worth it as apposed to a slightly lower ride height provided by springs.
Still would like to know if there’s any major difference between the RS and non RS cars that would prevent a set of springs from being compatible on one, while compatible on the other.
the difference is being designed around the strut/dds system vs not. I can’t tell you the dimensions and specificas, rsr downs for s/rs vs prem/luxe have different fronts spring rates though.
DDS should have a better ride quality with springs vs non dds + springs, and many people including myself with non dds + springs didnt notice really much difference on comfort, but car is much more stable and planted at speeds providing much more confidence, that floaty boaty feeling was almost eliminated from just the spring. Should be the same for DDS + springs only retaining even more comfort.
RSR downs provide a 1.2” drop front and rear, improves performance, and has very minimal increase to harshness, really none on “normal” roads. Pot holes, road transitions with “lips” very uneven roads, gravel/dirt roads sure. Normal FWY/HWY roads most likely not.
