Lowering Springs for Precision Package CT5-V Blackwing

[Paletero]

I recently picked up a 2025 CT5-V Blackwing with the Precision Package, and I’m currently looking into lowering spring options.

From what I’ve found so far, these are the three main options currently available:

However, from what I understand, all of these springs were developed for non-Precision Package Blackwings, but the Swift Spec-R springs are likely the closest match to the stiffer spring rates found in the Precision Package.

My main concern is I don’t want to downgrade the car’s handling by installing lowering springs that are softer or less capable than what comes with the Precision Package.

Do any of the current spring options have comparable spring rates to the Precision Package?

Is anyone currently working on lowering springs specifically for Precision Package Blackwings?

Appreciate any input especially from those who’ve tested or installed springs on a Precision Package car. Thanks!

Tuned coilovers is probably the only option to improving OEM IMO. I don't know of any manufacturers making them yet for the BW5 however.

I would go for coilovers over springs. Springs are mostly cosmetic in my opinion and I don't recommend but that's just me. I wouldn't recommend spacers either since that's cosmetic as well.

OP - I know you aren't asking for our opinions about whether you should or should not put lowering springs on your car but the mag ride is so awesome I just can't imagine messing with the springs. I've used springs in the past and always regretted it (and always ended up with proper high quality KW coilovers that were great). Keep in mind that a lowering spring shortens the amount of up travel in the suspension since, at static height, the shock shaft sits higher up in the damper tube.
