does overall ride comfort come from the spring rate of the springs and not the shocks? I understand how lowering your car will take away from OEM ride quality. But does anyone know the spring rate of the OEM springs? And what would be close to that as far as an aftermarket lowering spring?

Overall ride comfort comes from both spring rates and damper system. They need to be matched for your application. Having soft spring rates does not automatically make the ride soft. You can actually have worse ride quality with softer spring rates if your dampers are valved for something stiff.

so what would be the best overall spring for ride comfort? Fsport? I will pair them up with the fsport shocks

Best for comfort?

Probably the OEM non-sport-package springs and shocks.

no i mean best comfort lowering spring. I know the lower you go the less comfort. Im only looking for a minimal drop of 1"-1"1/2.

I just installed fsport springs and shocks and from my experience so far it is very close to stock comfort. You will feel a little more bumps but nothing significantly different...I was in the same boat as you, and did a lot of research bc I did not want to lose the ride comfort... I am very satisfied with this setup, everything I was looking for

yeah i guess as far as lowering springs go with a minimal drop they are probably the best choice, thanks

You'd want to match your spring rates and dampers for comfort. You can get any aftermarket spring and pop it in with your stock shocks and it'll still ride poorly since they're mismatched. Your two best options are: F-sport springs and f-sport shocks combo OR getting a set of coilovers. Because these are matched together, they'll ride great. With the coilovers you can always not slam it and lower the damper settings.

Just be careful though. A lot of coilovers aren't really matched at all. There is a general though that when you buy coilovers, the springs and shocks are matched. This is hardly the case because I've seen many coils with crap valving for the application. Some companies use the same damn dampers front and back with different spring rates slapped on. Heck, I've seen some coils using the same exact part numbers on two different cars, but because they're adjustable and they physically fit, it gets sold under that application Not really ideal, but then again, it's enough to get by for daily driving. Those who lower their cars by a good amount are going to sacrifice ride quality, to a degree anyways.

I posted the spring rates recently:

Here's F-sport brochure (w/spring rates).

IMO, selecting springs for comfort based on published specs (when they are available) is difficult.
