Second that. Stock is perfectly fine for daily driving and occasional fast road (2017 version is a bit firmer imo). Lowering springs if you want lower.

Unless you want more aggressive wheels or go on track, I think stock car is very capable (much better than some hot hatches i test drove). I had couple track days and 3 training days on testing circuit and stock was great.

What if you need the clearance for wheel specs (17x9et45 245/40) and plan to track in the future? Flex Z or A?

Either should be fine for clearance, but if you plan to track I would suggest As as you can adjust dampening. Makes quite a difference on some corners.

Stock is quite good. For improvements of street comfort and spirited driving performance, CSG Spec Flex A covers these avenues quite well.


Inexpensive way to lower the vehicle for the nice look, but does not always translate to a good ride quality unfortunately.

Depends on the spring? I just ordered some RCE Yellows. From what I've read it's a decent ride.

RCE Yellow and Swift Sport springs are designed accordingly as lowering springs but still does a decent job at allowing the shock function.

How about trd?
Im using trd springs

Their goal is to provide a system that provides a small enhancement to the factory system. It can be for looks, it can be performance, etc. Any lowering spring will give you something in the X category, but has to take away from the Y category.
